Description

[001] This application was filed on November 4, 2014 as an international PCT patent application and claims priority for the provisional patent application US 61/900,308, filed on November 5, 2013, and for the utility patent application US 14/531,395, filed November 3, 2014, both incorporated herein by reference in their entirety.

FIELD

[002] The present invention relates to a method and system for treating and building floating lakes, which are constructed within large bodies of water, where the quality and/or aesthetic characteristics of the water within the floating lakes are in accordance with different or more stringent recreational standards.

BACKGROUND

[003] Throughout the world, there are a large number of water bodies in which the microbiological, physico-chemical and/or aesthetic conditions of the body of water are not acceptable for recreational purposes, such as bathing and water sports. direct contact with water. The quality of the water in these water bodies is such that it poses potential health and safety risks for people who come into direct contact with the water. Furthermore, the aesthetic conditions of these bodies of water may not be attractive, pleasant and/or ideal which may still discourage recreational use. Golf course ponds, retention ponds, public park ponds, weirs, rivers, lakes, the ocean, ocean bays, river bays and more are examples of bodies of water that may have microbiological, physicochemical and /or aesthetics that make the water body unsuitable for recreational uses. These bodies of water can be found in the center of crowded cities, in rural areas or in low-population locations.

[004] As the world's population continues to increase, land is becoming a scarce resource with many areas of land becoming occupied at a high rate. Coastal areas attract many people because of their proximity to the sea or rivers. However, the rapid development of these areas often results in available land being used for housing or industry, which limits the opportunity to use the areas for recreational purposes. In non-coastal areas, many people do not have access to or do not live near bodies of water having water quality and/or aesthetic conditions suitable for recreational use. Within populous cities that have natural or artificial bodies of water, available land is typically used for housing or industry, leaving no available land spaces to generate bodies of water that can improve the quality of life for people in these cities by providing opportunity for the practice of water sports and other recreational uses associated with a body of water. Furthermore, bodies of water located within densely populated areas may not be suitable for recreational use because of debris, pollution, and/or unsafe conditions of the body of water (such as sloping bottoms, inferior clarity, and unknown submerged topography).

[005] Many people around the world aspire to access locations that have bodies of water similar to tropical seas, where the water quality has low turbidity, high transparency and clarity that generates a crystal clear water effect, and sandy bottoms. white that create an aesthetic appeal that is both attractive and desirable. The clarity of water within tropical seas attracts tourists from all over the world. For example, in 2012, areas in and around the Caribbean welcomed nearly 25 million tourists, 5.4% more than in 2011 and it is expected that this number will continue to grow annually. Given the large number of water bodies all over the world, there is a need to transform non-aesthetic and inferior water quality flowing water bodies in order to make them capable of effective use for recreational purposes in a safe way. For this reason it would be desirable to transform a body of water or a part thereof to provide a body of water having the water quality and aesthetic qualities provided by a tropical sea. The ability to transform such bodies of water would allow for the economic development of local communities as well as improving the lifestyle of a large proportion of people around the world by bringing an attractive tropical sea environment to an existing body of water not suitable for recreational purposes.

[006] Several studies have been performed on lakes, reservoirs and ponds in the United States. For example, of the more than 17 million acres of lakes, reservoirs and ponds assessed, more than 44% were found to be impaired for one or more uses. These water bodies were found to be affected by nutrients, metals, silting, total dissolved solids and excess algae growth among other effects. It has been determined that more than 41% of lakes within the United States present a high or moderate risk for potential exposure to algal toxins, which can potentially have a wide range of human health impacts. These studies also found that there are over 140,000 bodies of water that could potentially be used for recreational purposes, such as bathing or practicing water sports in direct contact with the water, if the water quality and/or aesthetic conditions were better. suitable. Generally speaking, these bodies of water are not suitable for recreational purposes because of poor water quality and/or aesthetic conditions that do not meet recreational or aesthetic water quality standards.

[007] Furthermore, many existing bodies of water, both natural and man-made, are unsuitable for recreational purposes and for water sports because of safety reasons associated with physical hazards such as strong currents, dangerous coastlines and/or natural resources. of uncertain or dangerous bottoms, and virtually none of them have the aesthetic characteristics of tropical seas. In these bodies of water, bathers or people participating in water sports may be exposed to one or more hazards. For example, drowning can occur if swimmers or water sport participants are caught in tidal currents or other types of currents or become caught in underwater obstacles. Bathers or water sport participants may also be injured by slipping or falling over rocks or general types of debris and/or by beach areas or other coastal areas having slopes that could be wrongly judged and pose safety hazards.

[008] In order to allow for recreational purposes, a body of water generally must comply with specific stringent regulations to avoid microbial and/or physiochemical contamination that can cause adverse health effects to recreational users. This is especially important in specific population groups that are at increased risk of disease, such as children and the elderly. Also, the effects of algae must be taken into account, as several human diseases have been reported to be associated with toxic species of algae that can be found in bodies of water. Such regulations aim to control the microbacteriological and/or physiochemical quality of the water to provide water that is safe for recreational use involving direct contact with water.

[009] There are also many bodies of water that have adequate water quality for recreational purposes, but they are not aesthetically attractive because of bottoms that are covered with sediment, debris, and/or mud that provide an unpleasant dark coloration to the body. of water. Water quality requirements for recreational purposes, therefore, often include requirements directed at the aesthetic condition of the water. These requirements generally state that the body of water must be free of floating debris, floating algae, oil, scum and other matter that may settle to form deposits, free of substances that can produce objectionable color, odor, taste or turbidity. , and free of substances that produce undesirable aquatic life. Regulations require water in recreational areas to be clear enough to allow users to estimate depth, be able to see underwater hazards easily, and to detect underwater debris or physical hazards such as rocks and sloping bottoms. Generally speaking, the amount of light that can reach the bottom of the body of water determines the clarity of the water. However, the depth of light penetration into natural or artificial bodies of water can be affected by suspended microscopic plants and animals, suspended mineral particles, stains that impart color, oils and foams, and floating and suspended debris such as leaves, litter and others.

[010] There are many locations around the world that can benefit from large bodies of water having water quality and/or aesthetic conditions suitable for recreational purposes and for the practice of water sports. However, such large bodies of water cannot be treated with current technologies or conventional pool filtration technology for obvious reasons based on their large sizes, which would require new structures, and considerably high amounts of chemicals and energy. In many instances, structural modifications of natural or man-made bodies of water must also be performed to address aesthetic conditions, such as changing a bottom that is covered with sediment, debris, and/or mud, and hazardous conditions, such as providing safe slopes to areas beach, among other requirements. Currently, there are no economically viable technologies that can completely change the entire water quality of large lakes or other large natural or artificial water bodies and/or provide an attractive color to bodies of water that already have good water quality but do not have aesthetic features that encourage recreational use. Therefore, there is a need for a system and methods capable of transforming a natural or artificial body of water to provide an area within the body of water having water quality and/or aesthetic qualities suitable for recreational use and for the practice of water sports.

PREVIOUS TECHNIQUE

[011] US patent 4,087,870 discloses a floating swimming pool assembly that includes walls made of a flexible blade, a floating edge part and a filtration assembly. The floating swimming pool is designed for conventional swimming pool treatment and provides operational characteristics similar to a permanent swimming pool installation, such as a conventional centralized filtration system that filters the total volume of water in the floating pool by 1 to 6 times. per day and a permanent chemical concentration. A system like this would not be suitable for use with a large floating pond, as it uses conventional swimming pool water treatment and filtration technology that is technically and economically not feasible for application to a large floating pond.

[012] US 2005/0198730 discloses a floating swimming pool apparatus. The main structural components of the device are constructed of a waterproof glass fiber reinforced plastic that is rigid, which results in considerably high material costs and does not provide the flexibility to handle water movement and structural loads associated with a large floating lake. Also, such an apparatus is very difficult to climb to large floating lakes because of its structural limitations.

SUMMARY

[013] The present invention relates to floating lakes and the treatment of water in such lakes. The present invention further relates to large floating lakes installed within a natural or artificial body of water.

[014] The dimensions of the floating lake, including the depth and surface area of the floating lake, may vary based on required and existing features, as well as the surface area and other physical features of the body of water. The floating lake can be provided with a chemical application system; a filtration system including a mobile suction device and filters; a skimmer system and may also comprise a coordination system. The system and method of the present invention can be configured to provide significant cost savings because of lower capital cost, energy consumption and chemical usage than conventional systems. This is because of the activation of the methods of the present application based on the actual requirements of the body of water, through evaluation of specific variables, also because of the lower ORP standards required when compared to conventional swimming pool treatment, and because of the use of an efficient filtration system based on the color of the floating lake bottoms.

[015] The present invention relates to a method for treating water in a floating lake installed in a body of water, the floating lake having walls and a bottom, wherein the bottom of the floating lake is constructed of a flexible material having a Young's modulus up to 20 GPa. The method generally comprises applying an oxidant to the water in the floating lake to maintain an ORP level of at least 550 mV for a minimum of about 10 to about 20 hours within a 52 hour cycle; applying a flocculant to the water in the floating lake before the turbidity of the body of water exceeds 5 NTU; vacuuming with a mobile suction device when the black color component of the floating lake bottom exceeds 30% on a CMYK scale, wherein the mobile suction device sucks up a portion of water from the floating lake floor containing settled solids; filter the water sucked in by the mobile suction device and return the filtered water to the floating pond; and providing water to the floating lake to maintain a positive pressure of at least 20 Newtons per square meter of the surface area of the floating lake, wherein the positive pressure is maintained for at least 50% of the time within 7 day intervals and in which water is supplied to the floating lake at a replacement rate according to the following equation: Replacement Rate > Evaporation Rate + Cleaning Rate + Leakage Rate.

[016] The present invention also concerns the structure of a floating lake. A floating lake of the invention generally comprises a flexible bottom having a Young's modulus of less than about 20 GPa; walls having an edge, the edge comprising a buoyancy system; a pumping system to maintain a positive pressure of at least 20 Newtons per square meter of floating lake surface area, wherein the positive pressure is maintained for at least 50% of the time within 7 day intervals; a chemical application system for applying chemicals such as an oxidant or flocculant to the water in the floating lake; a mobile suction device capable of moving along the flexible bottom of the floating lake and sucking up a part of water from the bottom containing settled solids; a filter system in fluid communication with the mobile suction system, wherein the filter system receives the part of water sucked in by the mobile suction system; a return line to return the water filtered by the filtration system to the floating lake. The system may also comprise a coordination system, wherein the coordination system activates the operation of the chemical application system.

DETAILED DESCRIPTION

[030] The following detailed description refers to the attached drawings. While embodiments of the invention may be described, modifications, adaptations and other implementations are possible. For example, substitutions, additions, or modifications may be made to elements illustrated in the drawings, and the methods described in this document may be modified by replacing, reordering, or adding stages to the disclosed methods. Therefore, the following detailed description does not limit the scope of the invention. While systems and methods are described in terms of “comprising” multiple apparatus or steps, systems and methods may also “consist essentially of” or “consist of” multiple apparatus or steps, unless otherwise stated. Systems and Methods of the Present Invention

[031] The present invention relates to floating lake systems and methods for treating and maintaining water quality in floating lakes.

[032] The present invention relates to large floating lakes with crystal clear water similar to that of tropical seas, where large floating lakes are generally installed within a natural or artificial body of water, such as an ocean, river, lake, reservoir, ponds, weirs, channels, inlets, estuaries, streams, ocean bays, river bays or other bodies of water. While the invention features embodiments such as "within" multiple bodies of water, it will be appreciated by those skilled in the art that the embodiment may include an edge that is adjacent to a coastline or beach.

[033] The present application also relates to a method for treating large floating lakes in order to take advantage of bodies of water throughout the world that suffer from poor water quality and/or inferior aesthetic characteristics, and to help improve the quality of life for people around the world. The floating lakes of the present application allow recreational uses, together with water sports in safe conditions, and can generate an unprecedented geographic impact on the amenities of cities around the world. The floating lakes of the present application generate an aesthetic resource that cannot be economically generated with current technologies, causing a greater impact on the use of natural or artificial bodies of water that were not previously considered useful.

[034] The dimensions of the floating lake, including the depth and surface area of the floating lake, may vary based on needed and existing features, as well as surface area and other physical features of the body of water, such as underwater obstacles, depth and more, on which the floating lake is built. For example, in some embodiments, the floating lake may have a surface area of at least 5,000 m2, or at least 10,000 m2, or at least 20,000 m2.

[035] One embodiment of the method for treatment concerns providing treatment of large floating lakes that are installed within natural or man-made bodies of water. Such natural or man-made bodies of water may have water quality that does not meet hygienic and/or aesthetic requirements for recreational purposes, or more stringent requirements. Specially designed floating pond systems are provided which enable the method of the present invention to be applied.

[036] According to the modalities, the floating lake can be installed in natural or artificial waters. Figures 1 and 2 show an exemplary embodiment of a floating lake installed in a natural channel. The floating lake, for example, may provide a recreational water resource in a city or other municipality in an area that otherwise does not provide water quality and/or aesthetic conditions suitable for recreational uses. The floating lake can be installed to improve water conditions that are not suitable for recreational uses because of chemical or biological pollution, safety issues or aesthetic reasons.

[037] The floating lake may be constructed to provide buoyancy and to accommodate changes in the water level of the surrounding body of water. For example, the floating lake system can be designed to be able to float with changes in the water level of the surrounding body of water. In such a case, when the water level of the surrounding body of water drops (eg at low tide), the complete floating lake system can be lowered with the surface of the natural body of water. On the other hand, when the water level of the surrounding body of water rises, the floating lake may rise with it. This is because floating lake systems' buoyancy systems provide buoyancy to the floating lake and are capable of keeping the surface of the floating lake at or near the surface level of surrounding bodies of water. In alternative embodiments, at least a portion of the floating lake bottom may be in contact with the bottom of the surrounding body of water at low water levels, or may be in contact with the bottom at all times.

[038] Changes in water levels and water movement in the floating lake and the surrounding body of water because of tides, currents and natural waves caused by wind and other phenomena can cause changes in pressure against or a load on the lake floor. floating. The structural stability of the floating lake can be considered when designing the structure, for example to deal with loads generated when the structure is vertically fixed in a position relative to the bottom of the surrounding body of water. The structure can be designed to handle such loads by providing a flexible but stable bottom that can oscillate or shift with the movement of the surrounding body of water. Also, the structure may comprise an anchoring system that provides vertical and/or horizontal support for the floating pond system to deal with submerged forces.

[039] According to an embodiment shown in figure 3, the floating pond 1 can comprise a flexible bottom 2 and walls 3. The bottom 2 and walls 3 can comprise a coating 200 constructed of impermeable materials that are capable of maintaining a body of water within the floating lake and essentially separating the water on the inside of the floating lake from the water in the surrounding artificial or natural body of water. Examples of suitable materials include, but are not limited to, rubbers, plastics, Teflon, low density polyethylene, high density polyethylene, polypropylene, nylon, polystyrene, polycarbonate, polyethylene terephthalate, fibers, fiberboard, wood, polyamides , PVC membranes, fabrics, composite fabrics, geomembranes, acrylics, among others and combinations thereof. The cladding 202 of the bottom 2 may be continuous with the cladding 203 of the walls 3. In an alternative embodiment, the cladding 202 of the bottom 2 is constructed of different materials than the cladding 203 of the walls 3.

[040] According to one embodiment, the bottom 2 and/or the walls 3 comprise a plurality of layers, where such layers can be of the same or different materials, and that can vary in their permeability. Additional layers can be provided to help prevent water leakage from the floating lake into the surrounding body of water. In order to reduce water loss from the floating lake to the surrounding body of water, a collection or drainage system can be provided between different layers of the bottom. Also, various structures can be used to provide a certain level of rigidity to the bottom and/or walls of the floating lake. A bottom 2 with a certain amount of flexibility may be able to better withstand punctures, ruptures and other damage to floating lake 1.

[041] The Young's modulus or modulus of elasticity of a material is a measure of the material's elasticity. Larger numbers indicate a stiffer material and smaller numbers a more elastic material. In order to provide a flexible bottom, the Young's modulus of the materials or components used in the bottom 2 is typically no greater than about 100 GPa, about 50 GPa, about 20 GPa, or about 15 GPa or 10 GPa. , allowing the bottom component to have flexibility and return to its natural state instead of deforming or breaking considerably because of loads applied to the material by the surrounding water, water in the floating lake or pressures resulting, for example, from the action of a suction device mobile.

[042] According to embodiments, the coating 200 is made of flexible components with a Young's modulus of up to about 20 GPa. In one embodiment, the coating 200 is made of flexible components with a Young's modulus of up to about 10 GPa. In another embodiment, the coating 200 is made of flexible components having a Young's modulus of from about 0.01 to about 20 GPa. In another embodiment, the coating 200 is made of flexible components having a Young's modulus of from about 0.01 to about 15 GPa. Also in another embodiment, the coating 200 is made of flexible components having a Young's modulus of from about 0.01 to about 10 GPa. Different parts of the cladding 200 (e.g., the underlayment 202 or the wall cladding 203) may be constructed of different components.

[043] Flexible bottom 2 provides many benefits for floating pond 1. For example, flexible bottom 2 offers a low cost option for floating pond structures, it can withstand pressure without being punctured or damaged, it is easy to install, and can accommodate water movement in and out of the floating lake. On the other hand, a completely rigid bottom would be very expensive, difficult to install, and would be easily damaged because of the large loads generated by the surrounding body of water. When using completely rigid bottoms, the loads generated by the surrounding water can cause materials to be loosened, the structure to be broken, and the water contained within the floating pond to be contaminated and mixed with the surrounding water, thus not achieving the quality. of water and/or aesthetic conditions required for recreational purposes.

[044] Bottom 2 of floating lake 1 may comprise one or more materials and configurations. In embodiments, the floating lake 1 may have a bottom 2 configured with one or more layers. As shown in figures 4A-4C, the bottom 2 may have a layered structure. In an embodiment shown in Figure 4A, the layer structure of the background 2 may comprise a single layer. In another embodiment shown in figure 4B, the layer structure of the bottom 2 may comprise two layers. Also in another embodiment shown in figure 4C, the layer structure of the background 2 may comprise multiple layers.

[045] The different layers can be combined to provide the bottom 2 with different characteristics, such as durability, impermeability, stability and rigidity and/or flexibility. In one embodiment, the bottom 2 and walls 3 are constructed of the same or similar materials. Alternatively, the bottom 2 can be constructed of different materials than the walls 3, or it can have a different layered structure. The Young's modulus of background material is used to refer to the background as a whole, which may comprise one or more different materials in different configurations.

[046] According to embodiments, the bottom 2 comprises components or materials such as rubbers, plastics, Teflon, low density polyethylene, high density polyethylene, polypropylene, nylon, polystyrene, polycarbonate, polyethylene terephthalate, fibers, fiber board , wood, polyamides, PVC membranes, fabrics, acrylics, among others, and combinations thereof that are capable of providing a flexible bottom with a total Young's modulus of up to 20 GPa. In many embodiments, each of the bottom 2 layers independently has a Young's modulus of at most 20 GPa.

[047] In an exemplary embodiment, the bottom 2 and walls 3 comprise a layer of fabric, for example a composite fabric, such as the Hipora® waterproof fabric consisting of a polyurethane-injected nylon fabric with waterproof features. The fabric can be sewn and sealed to generate the bottom 2 and walls 3 of the floating lake 1, creating a structure that can hold the water within the floating lake 1 substantially separate from the surrounding water, and protect the water of the floating lake against infiltration of water. surrounding water.

[048] In another exemplary embodiment, the bottom 2 and walls 3 comprise a layer of linear low density polyethylene ("LLDPE"). For example, the bottom 2 and walls 3 may comprise an LLDPE geomembrane which may be thermofused, welded or glued together with a sealer suitable for prolonged contact with water. In another exemplary embodiment, the bottom 2 and the walls 3 comprise a layer of a high-strength PVC material. Other suitable materials include geotextiles, PVC materials, sprays of elastomeric or polymer materials or as multi-layer bitumen geocomposites. The coating thickness can be any thickness suitable for the purpose and can be adjusted to meet the requirements of the floating pond 1 such as, for example, durability, puncture resistance, stability and rigidity/flexibility. The thickness of the coating can be, for example, about 0.4mm, 0.5mm, 0.75mm, 1mm or thicker. The coating can be included as a layer in a layer structure, such as the multilayer structure in Figure 4C. Sealers suitable for joining sections of the bottom 2 together or to the walls 2 are butyl tapes, being waterproof, and self-adhesive flexible adhesive sealing tape capable of adhering to plastics. Waterproof materials and sealing techniques, such as thermofusion, welding or gluing, also make it possible to generate a structure that can substantially separate the water in the floating lake 1 from the surrounding water.

[049] The bottom may also include one or more structural frameworks. Structural frames can be constructed to accommodate a modular floating pond system configuration. As can be seen in Figure 10A, the floating lake 1 may comprise one or more structural frames 15 located on the bottom of the floating lake 1. The structural frames may be constructed to be positioned under or on top of the layered structure of the bottom 2, or between layers. However, structural frameworks are preferably positioned under the bottom in order to provide the structure, but without affecting the impermeability of the floating pond. Structural frame 15 can be joined together in a configuration based on the shape of the floating lake bottom 1 to provide additional stability to the bottom. In figure 10B, an embodiment of the floating pond 1 is shown, comprising a bottom 2 with structural frames 15, walls 3 and buoyancy systems 5. In at least some embodiments, structural frames 15 can also be provided on walls 3 of floating pond 1, to provide more stability and to maintain the shape of floating pond 1. Structural frame 15 can be connected to rim 4 and/or flotation system 5.

[050] Structural framework 15 can be constructed of rigid or flexible materials. Materials can be selected to be suitable for submerged conditions, as the structural framework will generally be submerged. Rigid frames, tubes or profiles to generate a rigid structural frame can be constructed of any suitable materials. Examples of rigid materials include metals such as steel or aluminum, plastics, wood and concrete, among other materials. Flexible frames, tubes, hoses or profiles to generate a flexible structural frame can be constructed of any materials suitable for building a flexible structure. Examples of flexible materials include plastics, rubbers, fabrics and nylon, among other materials.

[051] Structural frame 15 can be constructed from frame components 150 that can be connected together using connectors 151. Connectors 151 and connector materials can be selected based on design configuration and materials of frame components 150 The frame connectors 151 may include flexible or rigid materials. Suitable frame connectors 151 include rings, mechanical joining systems such as soldering, plates, screws, cables and so on. Connectors 151 can still be used to connect frame components 150 to the rest of the floating pond structure 1.

[052] According to embodiments, the walls 3 may further include an edge 4, as shown in figures 3 and 5-7. Edge 4 may comprise structural frame components 150 and may be covered at least partially by cladding 200. Edge 4 of floating lake 1 may comprise a buoyancy system 5 (shown in Figures 3 and 5-7). The buoyancy system 5 provides buoyancy and allows to maintain a water level in the floating lake 1 which generates a positive pressure in the floating lake 1. The buoyancy system 5 can also provide stability for the perimeter of the floating lake 1 and can help the floating lake 1 to maintain its surface shape. The buoyancy system 5 can comprise a plurality of buoyancy elements distributed along the perimeter of the floating lake 1, or a continuous buoyancy element surrounding the perimeter of the floating lake 1. The buoyancy system 5 can be attached to the liner 200, and /or may be at least partially covered by coating 200, as shown in Figures 5-7. The buoyancy system 5 can still be fixed to the structural frame 15.

[053] The flotation system 5 along the edge 4 or the walls 3 of the floating lake 1 may comprise different materials and flotation equipment, such as polyurethane systems; polystyrene systems, such as extruded polystyrene and expanded bead polystyrene; polyethylene systems; air-filled systems, such as air chambers, rubber air bags, or vinyl air bags; and systems constructed of other suitable materials such as plastics, foams, rubbers, vinyl, resins, concrete, aluminum and different types of wood, among others. Examples of commercially available buoyancy materials are Royalex® (a composite material comprising an outer layer of vinyl and hard acrylonitrile butadiene styrene (ABS) plastic and an inner layer of ABS foam, Styrofoam, and high-quality extruded closed cell polyethylene foams). performance, such as Ethafoam™).

[054] The size and type of the buoyancy elements can be determined based on the volume of the floating lake 1, the amount of water disposed in the floating lake 1 and the desired buoyancy to be provided by the buoyancy elements. For example, the buoyancy system 5 can be sized to provide sufficient buoyancy for the floating lake 1 such that the floating lake 1 remains afloat (i.e. not making contact with the bottom of the surrounding body of water) even at pressures high internals. Alternatively, the flotation system 5 and the depth of the floating lake 1 can be designed in such a way that at least a part of the bottom of the floating lake 1 comes into contact with the bottom of the surrounding body of water.

[055] In one embodiment, additional features can be added to floating lake 1. For example, edge 4 of floating lake 1 can be constructed to comprise beaches, walkways, pedestrian walkways, jetties, handrails, sloping entry systems and/or or various other amenities. Additional features can also be optionally attached to the outer perimeter or inner perimeter of the floating lake 1, such as floating docks, which can be modular or fixed arrangements, floating platforms, pontoons and others.

[056] Floating lake 1 can be anchored or fixed in place within the surrounding body of water. For example, the floating lake 1 may be anchored to the bottom of the surrounding body of water and/or may be fixed or attached to the shore of the surrounding body of water. The floating pond 1 may comprise multiple anchor points 210 by which the floating pond can be tied by cables 220 to anchor points or corresponding anchors at the bottom or along the edge of the surrounding water, shown in Figure 3. The number and location of the Anchor points 210 can be configured based on the size of the floating lake 1, and the size and conditions (e.g., typical weather, tides and currents) of the surrounding water. Anchor points 210 may be reinforced and may comprise any suitable materials such as, for example, plastic, metal, concrete and combinations thereof. According to one embodiment, the cables 220 connecting the floating lake 1 to the anchors may be adjustable and/or extendable. This will allow for increased flexibility as needed. For example, if increased currents or waves are observed in the surrounding body of water, the length of the cable can be increased (or decreased), manually or automatically, to prevent the resulting forces from putting pressure on the floating lake material.

[057] In one embodiment, floating lake 1 is designed and configured to be anchored to land along a section of edge 4 of floating lake 1. As can be seen in Figure 9A, floating lake 1 can be moored land directly or through a 10-deck system that provides adequate and safe entry of people from land to the floating lake system. In another embodiment, as shown in Figure 9B, the floating lake 1 is separated from the mainland and is located outside the shore of the surrounding body of water. Floating pond 1 can be connected to mainland via a deck/bridge system 11 that allows safe and proper entry of people from mainland to the floating pond system. In another embodiment, the floating lake system is not connected to land and can be accessed through the surrounding natural or artificial body of water.

[058] According to one embodiment, a positive pressure is provided in the floating lake 1. Positive pressure within the floating lake can be used to ensure that the water contained in the floating lake 1 will not be contaminated by the surrounding water in the event of a drilling or damage to the bottom 2 or walls 3, and to help maintain the shape of the floating lake 1. Positive pressure within the lake will allow the water inside the floating lake 1 to flow into the surrounding body of water, and for this reason the water inside floating lake 1 would not be contaminated. In order to maintain positive pressure in the event of damage to the bottom 2 or walls 3 of floating lake 1, water can be added to floating lake 1 at a rate that maintains a positive pressure within floating lake 1.

[059] According to one embodiment, positive pressure can be maintained within the floating lake 1 by keeping the surface 6 of the water in the floating lake 1 above the water level 100 of the surrounding body of water, i.e., by slightly overfilling the floating lake 1. Without such additional filling, floating lake 1 will assume its normal shape and volume. However, as the walls 3 and bottom 2 of floating pond 1 are constructed of flexible materials, the materials will bend under the weight of the water when floating pond 1 is overfilled. Bending of materials will cause the actual water level in floating lake 1 to become similar or equal to the surrounding water level, while still maintaining the desired positive pressure.

[060] Although in practice the water level approximately equals the level of the surrounding water, the theoretical increase in water level can be used to calculate the additional volume of water needed to create the desired positive pressure. For example, if the water level within the floating lake is desired to be 2 mm above the water level of the surrounding water, the volume of water above the level can be calculated by multiplying the water surface by the height of the level above the water. . In practice, however, because of the flexibility of the walls 3 of the floating lake 1, that is, the structure separating the volume of the floating lake from the surrounding water, when the above-level volume is added, the walls 3 of the floating lake 1 expand, and the actual water level in the floating lake becomes similar or equal to the surrounding water level.

[061] In a preferred embodiment, the positive pressure should be at least about 20 Newtons per square meter (N/m2) on the inner surface of the floating lake to prevent water from the surrounding water from entering the floating lake 1 in the event of puncture or other damage. In other embodiments, the positive pressure is at least about 10 N/m2, about 15 N/m2, about 18 N/m2, about 25 N/m2, or about 30 N/m2. A positive pressure of at least 20 N/m2 is equivalent to keeping the surface 6 of the water in the floating lake 1 at least about 2 mm above the surface 100 of the surrounding water, generating a volume of water that is above the surrounding water level . As discussed, the rise in water level is theoretical and in reality the walls 3 and bottom 2 of floating lake 1 flex to accommodate the extra volume of water, and the water level of floating lake 1 and the surrounding body of water. are approximately equal. Therefore, such a positive pressure can also be based on the extra volume of water that exceeds the initial volume of water in floating lake 1 in its natural (unflexed) state.

[062] Positive pressure can be maintained in floating lake 1 by pumping water into the lake through a pumping system as required to maintain the desired pressure. For example, positive pressure can be maintained by pumping water for a period of time that is not less than 50% of the time within a 7 day period. Preferably, positive pressure is continuously maintained in the floating lake. The higher internal pressure in the floating lake 1 is balanced by the buoyancy provided by the buoyancy system 5. In one embodiment, the size of the buoyancy system 5 and the buoyancy provided by the buoyancy materials are configured to match the load exerted by the pressure. positive caused by the extra volume of water and by users and equipment that are in or around the floating lake 1. The size and shape of the buoyancy system 5 can be adjusted (by adding or removing buoyant material) in order to change its buoyancy to account for the resulting loads.

[063] According to one embodiment, the floating lake 1 may comprise a coordination system, where the coordination system can receive information regarding water quality and physicochemical parameters, process the information and activate processes to maintain the quality parameters. of water and other physicochemical parameters within pre-established limits. The floating lake may comprise a coordination system to maintain the water quality and other physicochemical parameters in the floating lake within predetermined ranges. The coordination system allows activating the operation of different processes, which can be done automatically with an assembly of coordination and control units receiving information, or manually by entering and/or processing the information manually.

[064] In optional embodiments, the coordination system includes several sensors arranged in and around the floating lake. Information from sensors can be input, manually or automatically, into a computer that processes the information. The coordination device may simply provide instructions to be carried out by a person, or it may direct the correct action automatically.

[065] According to an exemplary embodiment shown in figure 5, the coordination system comprises a coordination assembly 20 capable of obtaining and/or receiving information (for example, from sensors arranged in and around the floating lake 1 and in the water surroundings), process the information and activate processes (by providing instructions or activating such processes automatically) based on the information received. Coordinating assembly 20 may include a control unit 22, such as a computer, and at least one monitoring device 24, such as a sensor. The sensor may be an oxidation-reduction potential ("ORP") meter, turbidity meter, or other apparatus for measuring a water quality parameter. In accordance with other embodiments, the coordination assembly 20 may include two or more monitoring devices 24. The coordination assembly 20 may also comprise additional monitoring devices 24 for other water quality parameters, such as pH, alkalinity, hardness ( Calcium), chlorine and microbial growth, among others.

[066] According to alternative modalities, the coordination system can be replaced by one or more people to obtain and/or enter and/or process information manually, or to activate and/or execute processes to maintain water quality parameters and /or other physicochemical parameters. The processes may comprise adding water treatment chemicals and/or operating a mobile suction device, among others.

[067] According to one embodiment, the coordination system may comprise an automated system. The automated system can be programmed to monitor water quality parameters and/or physicochemical parameters continuously or at pre-set time intervals, and activate one or more systems. For example, the automated system can activate the addition of chemicals to treat the water when it detects a passage of a predetermined value. According to an alternative embodiment, the coordination system comprises manually controlling the addition of treatment chemicals based on an empirical or visual determination of water quality parameters.

[068] The floating lake 1 may comprise a system for adding treatment chemicals to the water. According to the embodiment shown in Figure 5, the system for adding treatment chemicals comprises a chemical application system 30. The chemical application system 30 can be automated and can be controlled by the control unit 22 of the assembly. of coordination 20.

[069] According to an alternative embodiment shown in Figure 6, the chemical application system 30 can be manually operated or activated based on water quality parameters. For example, water quality parameters can be obtained manually, through empirical or analytical methods, such as algorithms, based on experience, visual inspection or when using a sensor, and information about the water quality parameters. it can be processed manually or be fed into a processing device (eg a computer). Based on information regarding the water quality parameters, operation of the chemical application system 30 can be activated manually, for example by activating a switch.

[070] The chemical application system 30 can be operated on-site or via a remote connection (e.g. via the Internet), where the information is sent to a central processing unit and can be accessed via the connection. remote, allowing you to activate the operation of the chemical application system 30.

[071] The chemical application system 30 may comprise at least a chemical reservoir, a chemical metering pump and a dispensing apparatus. Chemical delivery system 30 may comprise multiple chemical reservoirs to house separate treatment chemicals such as oxidants, flocculants and the like. The pump can be triggered by a signal from the control unit 22 or manually by activating a switch locally or remotely. The dispensing apparatus may comprise any suitable dispensing mechanism, such as an injector, a sprinkler, a dispenser, tubing, or combinations thereof.

[072] Figure 7 shows an alternative embodiment where chemicals can be dosed manually into the water or when using a separate chemical delivery mechanism. For example, water quality parameters can be obtained manually, visually or using a sensor, and information about the water quality parameters can be processed manually or entered into a processing device (e.g. a computer) . Based on information regarding water quality parameters, chemicals can be added to the water manually.

[073] Bottom 2 of floating lake 1 can be cleaned using a mobile suction device 42 which is capable of moving along bottom 2 of floating lake 1 to remove sedimented particles on bottom 2. Bottom 2 of floating lake 1 can be cleaned intermittently to provide an attractive coloration to the body of water and prevent accumulation of sedimented material and debris found on the bottom 2. Typically, the mobile suction device 42 is capable of cleaning a flexible bottom 2 with a Young's module of up to 20 GPa.

[074] The floating lake 1 typically also includes a filtration system 40. According to one embodiment, filtering only a portion of the water in the floating lake is sufficient to maintain the water quality within the desired water quality and physicochemical parameters. . As seen in figures 5-7, the filter system 40 includes at least one mobile suction device 42 and an associated filter system 44. The mobile suction device 42 is configured to suck up a part of water from the bottom 2 of the lake. float 1 that contains fragments, particulates, solids, flocs, flocculated materials and/or other impurities that have settled to the bottom 2. Vacuuming and filtering this part of the volume of water in the floating pond provides the desired water quality without a filtration system that filters the total volume of water from the floating lake, which is in contrast to conventional swimming pool filtration technologies that require filtering the total volume of water 1 to 6 times a day.

[075] According to one embodiment, the mobile suction device 42 is capable of moving along the bottom 2 of the floating lake 1. However, to maximize the efficiency of removing fragments, particulates, solids, flocculates, flocculated materials and/or or other impurities that have settled on the bottom 2, the mobile suction device 42 can be configured in such a way that its movement creates minimal dispersion of the settled materials. In embodiments, the mobile suction device 42 is configured not to include parts, such as rotating brushes, which can function to re-disperse a substantial part of the sedimented materials on the bottom 2 of the floating lake 1 during operation of the suction device.

[076] The activation of the operation of the mobile suction device 42 can be controlled by a coordination system including a control unit 22 or manually by an operator. According to an embodiment shown in figure 5, activation of the operation of the mobile suction device 42 is controlled by the control unit 22. Figures 6 and 7 show alternative embodiments where the mobile suction device 42 is manually activated such as, for example , when activating a switch or sending an activation message.

[077] The mobile suction device 42 may comprise a pump, or a separate pump or pump station may be provided to suck the water into the pump and the suction water into the filtration system 44. The separate pump or pump station may be located within the floating lake 1, along the perimeter of the floating lake 1, or outside the floating lake 1, for example, on the shore of the surrounding body of water.

[078] The mobile suction device 42 is in fluid communication with the filtration system 44. The filtration system 44 generally includes one or more filters, such as a cartridge filter, sand filter, microfilter, ultrafilter , nanofilter or a combination thereof. The mobile suction device 42 is typically connected to the filtration system 44 by a collection line 43 comprising a flexible hose, rigid hose, a tube, among others. The filtration system 44 may be located along the perimeter of the floating lake 1, in a floating facility, or along the shoreline of the surrounding body of water. The capacity of the filter system 44 is generally scaled to the capacity of the mobile suction device 42. The filter system 44 filters the flow of water from the mobile suction device, corresponding to a small part of the volume of water in the floating lake. Filtered water from the filtration system 44 is returned to the floating pond by a return line 60 comprising a flexible hose, rigid hose, a tube, an open channel, among others. The location of returning water can be optimized to minimize the cost of pumping the water.

[079] Compared to a conventional filtration system capable of filtering the entire body of water in the pool 1 to 6 times a day, the filtration system 44 of the present application can be configured to have a filtration capacity that is approximately 1/2 10 of that of the conventional system, or approximately 1/30 of that of the conventional system, or approximately 1/60 of that of the conventional system, or approximately 1/100 of that of the conventional system, or approximately 1/300 of that of the conventional system. This translates to a daily filtration capacity that is in the range of about 1:10, or about 1:25, about 1:50, about 1:75, about 1:100, about of 1:200, or about 1:300 of the floating lake volume. The power consumption of the filtration system is approximately proportional to the size and thus significant cost savings can be expected with lower power consumption, and requiring less equipment for the filtration process.

[080] In one embodiment, the mobile suction device 42 may comprise a magnetic system adapted to clean submerged flexible bottoms. Improved cleaning of a floating pond with a flexible bottom can be achieved with a mobile suction device which is capable of adhering to bottom material with opposing magnetic components. As shown in figure 8, the mobile magnetic suction device 420 having a magnetic system comprises an internal component 430 and an external component 435. The internal component 430 is placed on the bottom 2 of the floating lake 1 on the inside of the floating lake. 1, in contact with the water of the floating lake 1. The internal component 430 may include at least one suction apparatus 431. The external component 435 is placed on the outside of the floating lake 1 in contact with the surrounding water.

[081] The magnetic system may comprise two or more magnetic components (432, 436) capable of attracting each other. The magnetic components 432, 436 can have opposing magnetic fields, or at least one of the magnetic components has a magnetic field and one or more of the magnetic components are ferromagnetic (i.e., attracted to the magnetic field). The inner component 430 of the mobile suction device 420, which includes the suction apparatus 431, comprises a first magnetic component 432. The inner component 430 with the first magnetic component 432 is placed along the inner surface of the bottom 2 of the floating lake. 1. The outer component 435 comprises a second magnetic component 436 which is placed on the outer surface of the bottom 2 and is in contact with the surrounding water. The first and second magnetic components 432, 436 are aligned at corresponding locations along the bottom 2 of the floating lake 1 such that the magnetic attraction maintains the alignment of the first and second magnetic components 432, 436. The magnetic system is thus capable of holding the mobile suction device 420 along the flexible bottom 2 of the floating lake 1. The internal and external components 430, 435 of the mobile suction device 420 may comprise brushes, rollers, tracks, screws or other mechanisms to drive the suction device moving magnet 420 along the bottom 2.

[082] In one embodiment, the inner component 430 is pushed along the bottom 2 of the floating lake 1 and, because of interactions between the first and second magnetic components 432, 436, the outer component 435 is pulled together in such a way that it remains adjacent to the inner component 430. In an alternative embodiment, instead of the inner component 430 pulling on the outer component 435, the outer component 435 is pushed along the outer surface of the bottom 2 and pulls on the inner component 430 and the recording apparatus. aspiration 431 along with it. This can be accomplished, for example, by providing the outer surface of the bottom 2 with a drive system which may comprise raceways, threads or some other configuration allowing the outer component 435 to be dragged along the outer surface of the bottom 2. drive system along the outer surface of the bottom 2 allows for a cheaper and lighter inner component 430.

[083] In another embodiment, the mobile suction device 42 comprises a flexible mobile suction device that moves on the bottom of the floating lake, where the floating lake 1 provides a stable bottom for the mobile suction device to move on it. . The flexible mobile suction device can adapt to the stable bottom, which is flexible, in order to clean it thoroughly.

[084] In yet a further embodiment, the bottom 2 of the floating lake 1 comprises a layered structure. As can be seen in Figures 11A and 11B, in an exemplary embodiment, the layered structure comprises a layered material such as a buffer-like material filled with air, water or other liquid captured between the layers, functioning as a buffer. extra 16 with water or air between the water inside the floating lake and the surrounding water. This damper 16 can provide the bottom 2 with stability and allow, for example, more efficient operation of the suction apparatus. The damper can also be filled with expandable foam materials.

[085] In another embodiment, the liner comprises a series of inflatable sections 17 in the liner, distributed along the bottom 2 of the floating lake 1. As shown in Figure 12A, the inflatable sections 17 are attached to the bottom and can be inflated. in such a way that the inflatable section 17 expands up (figure 12B) or down (figure 12C) from the bottom 2, depending on the configuration and fabrication of the inflatable sections 17. It is recommended that the inflatable sections 17 be configured on the outside of the bottom (as shown in figure 12C), on the side of the surrounding body of water, in order not to affect the flat bottom of the floating lake.

[086] The inflatable sections 17 can take a variety of forms. In one embodiment, the sections are substantially rectangular, covering the entire surface area of the cladding 200 and dividing it into separate sections. In other embodiments, however, the inflatable sections 17 have other shapes, such as triangular or pentagonal, as necessary in order to effectively support the operation of the suction device 42 and counter external forces. The inflatable sections 17 can also be in the form of tubes, forming the perimeter of the various shapes, thereby reducing the surface area that needs to be inflated. Inflation of the sections may be carried out in any usual manner such as, for example, by providing the liner 200 with integrated inflation conduits, connected to one or more pumps, permanently or as needed. Although in many embodiments the inflatable sections 17 are inflated with air, more purified gases or other fluids can be used, such as water or fluids having a density less than that of the surrounding water. Also, some of the inflatable sections 17 of a plurality of the inflatable sections 17 may be filled with a liquid or gas, while others are filled with another liquid or gas, or the inflatable sections 17 may be filled with a mixture of liquid and gas. (e.g. water and air), to achieve different buoyancy within sections.

[087] These inflatable sections 17 can be permanently inflated during installation or selectively inflated when necessary. For example, the inflatable section 17 may be permanently or selectively inflated to make the bottom stable enough to support the weight and movement of the suction device 42. Other uses of the selectively inflatable sections may be when certain forces are expected such as such as increased winds or waves - caused by storms or large ships.

[088] The lining with the inflatable sections 17 can also be incorporated into a larger structure. The larger the structure can be, the thicker the liner 200, where the inflatable sections 17 comprise an additional layer of liner 200. The other layers may or may not have their own inflatable sections 17. If the other layer(s) (s) have(have) the inflatable sections 17, such sections may be aligned with the respective additional inflatable sections 17. Also, the underlayment 202 may be attached to rigid structures (e.g., structural frameworks 15) in order to provide tension to the underlay material and secure anchor systems.

[089] The floating lake 1 may also include a defoaming system 50. The defoaming system 50 may be used to separate floating debris and oils and greases from the water. As shown in Figures 5-7, the skimmer system 50 may include a skimmer 52 which removes the foam from the surface water of the floating lake 1, in fluid communication with a separation system 54. The skimmer 52 of a generally it is connected to the separation system 54 by a connection line 53 comprising a flexible hose, rigid hose, a tube, an open channel, among others. Because of the different nature and qualities of the impurities (eg oil, grease and floating debris) in the skimmed water compared to the impurities at the bottom 2 of the floating lake 1, skimmed water usually does not need to be filtered. Therefore, according to one embodiment, the separation system 54 may comprise a degreaser (e.g., an overflow apparatus) for separating oils and greases from the water and a screen or coarse filter for separating debris. Water from the separation system 54 may be returned to the floating pond 1 via the return line 60. The return line 60 may be the same as, or may be separate from, the return line of the filtration system 40. According to an embodiment , the skimming system 50 includes multiple skimmers 52 that can be spread along the perimeter of the floating lake 1. Figure 5 shows a skimmer 52 and a second skimmer 52 shown in dashed lines to represent a plurality of skimmers. Operation of the defoaming system 50 is preferably continuous, or alternatively may be intermittent. The operation of the defoaming system 50 can be controlled by the control unit 22 (FIG. 5) or manually (FIG. 6). Floating Lakes Operation

[090] Currently, floating swimming pools are very uncommon, and floating pools found on the market are small in size and are operated like conventional swimming pools. Conventional floating swimming pools are typically built and operated to swimming pool standards, which require permanent high levels of chemicals and filtration of the total body of water 1 to 6 times a day. Applying conventional swimming pool technology to the floating lakes of the present invention would give rise to two main problems: (1) High cost of applying swimming pool technology to large bodies of water because of the use of high rates of chemicals and filtering the entire volume of water 1 to 6 times a day with a conventional centralized filtration system; and (2) a possible hazard that could occur in the event of damage to the bottom or walls of the floating lake. Different technology and a maintenance method must be used to maintain sanitation standards in large floating lakes because, when using conventional swimming pool technology, water with a high chemical content can potentially be released into the surrounding body of water, adversely affecting aquatic and marine life or freshwater environment. Therefore, the use of conventional swimming pool technology should be avoided in order to conserve energy and protect the ecosystem of the surrounding body of water.

[091] According to one embodiment, water quality and physicochemical conditions are maintained in floating lake 1 through processes comprising adding treatment chemicals and removing fragments, particulates, solids, flocs, flocculated materials and/or other impurities. of the floating lake bottom according to water quality parameters and/or physicochemical conditions. Water quality in floating lake 1 can be obtained, for example, for specific parameters such as oxidation and reduction potential (“ORP”), turbidity, pH, alkalinity, hardness (Calcium), chlorine, microbial growth, among others. The chemical application system can be activated at the right time by the coordination system to keep the water quality parameters within established limits. Systems can be activated based on an actual need, resulting in the application of lesser amounts of chemicals and using less energy than conventional swimming pool water treatment methods.

[092] In embodiments, water quality parameters can be obtained manually, for example by visual inspection, when using a water quality meter (e.g. a probe such as a pH probe, a turbidity meter, a colorimeter or an ORP meter), or when taking a sample and measuring water quality using an analytical method. Information regarding water quality parameters can be obtained or entered into the coordination system. In one embodiment, an automated coordination system can be programmed to monitor water quality parameters continuously or at pre-set time intervals, to compare results to a predetermined parameter, and to activate one or more systems when the parameter has been crossed. For example, the automated system may trigger addition of treatment chemicals or operation of a filtration system upon detecting a crossing of a predetermined parameter. In an alternative embodiment, water quality parameters can be obtained manually and the information entered into the coordination system, or the results can be compared to a predetermined value and addition of treatment chemicals can be activated manually. Treatment chemicals used to maintain water quality in the floating lake may comprise any suitable water quality treatment chemicals. For example, treatment chemicals may comprise oxidants, flocculants, coagulants, algaecides, sterilizing agents, or pH-regulating agents. In a preferred embodiment, the treatment chemicals comprise an oxidant and a flocculant.

[093] The water quality parameters can be obtained according to the requirements of the floating lake, continuously or at certain time intervals. In one embodiment, the ORP (or other water quality parameter) of the water is determined by means of a monitoring device 24 (system of Figure 5), such as a sensor, or by means of empirical or analytical methods, such as as experience-based algorithms, or visual inspection (systems in figures 6 and 7).

[094] The ORP of the water in the floating lake is maintained at the minimum ORP for a minimum period of time within 52 hour cycles to provide water having the desired water quality. An oxidant is applied to the water in the floating lake to maintain an ORP above a minimum value for a minimum period of time within a 52 hour cycle (eg the treatment cycle). In modalities, the ORP level is maintained at about 550 mV or higher. Such a minimum ORP level is much lower than the ORP level typically maintained in swimming pools to achieve sufficient disinfection. The ORP treatment time within the 52 hour cycle can be continuous, periodic, intermittent or discontinuous. In embodiments, the minimum period of time is from about 10 to about 20 hours within the 52 hour cycles. While it is possible to maintain the minimum ORP level continuously, i.e. 24 hours/day, the ORP level can also be maintained only during specific periods such as, for example, the minimum periods, double the minimum period, or spaced at intervals of 4, 6, 8, 10 or 12 hours during which the ORP level is not maintained. The oxidant may be selected from halogen based compounds, permanganate salts, peroxides, ozone, sodium persulfate, potassium persulfate, an oxidant produced by an electrolytic method, or combinations thereof. The amount of oxidant added to the water (the "effective amount") can be predetermined or can be determined (e.g., by control device 22 in Figure 5 or manually) based on the measured ORP and the desired increase in ORP of the water.

[095] Water turbidity can also be monitored to maintain water quality in the floating lake 1. Flocculants and/or coagulants can be added to aggregate, agglomerate, coalesce and/or solidify suspended solids, organic matter, inorganic matter, bacteria , algae and more into particles that then settle to the bottom of the floating lake. For example, flocculants can be added to water in order to induce the flocculation of turbidity-causing suspended solids, such as organic and inorganic matter, and for this reason aid in the sedimentation process of such particles where they can be removed by the dewatering device. mobile suction. Generally, the flocculant or coagulant is applied or dispersed in the water by the chemical delivery system. Suitable flocculants or coagulants include, but are not limited to, synthetic polymers such as polymers containing quaternary ammonium and polycationic polymers (e.g. polyquaternium), cationic and anionic polymers, aluminum salts, aluminum hydrochloride, alum, aluminum sulfate, calcium oxide, calcium hydroxide, ferrous sulfate, ferric chloride, polyacrylamide, sodium aluminate, sodium silicate, chitosan, gelatin, guar gum, alginate, moringa seeds, starch derivatives, or other components with flocculating properties and combinations thereof same.

[096] In one embodiment, the addition of flocculants is activated before the turbidity of the water exceeds a predetermined value, such as 2 NTU (Nephelometric Turbidity Units), 3 NTU, 4 NTU or 5 NTU. The coordination system can be used to activate the addition of flocculants and/or coagulants before the turbidity of the water exceeds the predetermined value in order to cause flocculation and sedimentation of organic and inorganic matter. The fraction of water in which flocs accumulate or generally settle is the water layer along the bottom 2 of the floating lake 1. The flocs settle on the bottom 2 of the floating lake 1 and can then be removed by the mobile suction device 42 without requiring all water in floating lake 1 to be filtered; for example, only a small fraction is filtered. The “small fraction” of water being filtered can be less than about 30%, less than about 25%, less than about 20%, less than about 15%, less than about 10%, less than about , 9%, less than about 8%, less than about 7%, less than about 6%, less than about 5%, less than about 4%, less than about 3%, less than about 3% 2%, less than about 1%, less than about 0.9%, less than about 0.8%, less than about 0.7%, less than about 0.6%, or less than about 0.5% per day of the total volume of water in the floating lake. The amount of flocculant added to the water can be predetermined or can be determined (e.g., by the control device 22 in Figure 5 or manually) based on the turbidity and the desired reduction in turbidity of the water. The water treatment chemical preferably can also have algaecidal properties.

[097] The dosage of water treatment chemicals, such as oxidants and flocculants, can be done keeping in mind possible contamination and risks to the surrounding body of water in the event of damage to the bottom or walls of the floating structure, or in case of water contained within the floating lake being transferred to the surrounding body of water for any other reason.

[098] Sedimentation of particulates, solids, floccules, flocculated materials and/or other impurities on the bottom 2 of floating lake 1 can cause a change in the appearance of the color of the bottom 2 of floating lake 1. For example, sedimented impurities can cause the background color 2 appears darker than the original color. According to the method, the color of the bottom 2 of the floating lake 1 is monitored, and when the color has changed by a predetermined amount the aspiration of water and impurities from the bottom 2 of the floating lake 1 is activated. The measured or perceived color, which can be obtained through empirical or analytical methods, such as experience-based algorithms, visual inspection, automated equipment, or others, can be compared to a predetermined value, such as an increase in a component. color (eg black) of the actual background color 2.

[099] It will be appreciated by those skilled in the art that in the context of background color 2, the term “background” refers to the surface of the uppermost layer of background 2 that is visible above background 2.

[0100] In an exemplary embodiment, the background color 2 of floating lake 1 can be monitored for changes in the black component on a CMYK scale or other suitable color scale. The CMYK color scale uses four colors expressed in percentages: cyan, magenta, yellow, and black. The K component of the CMYK scale is the black component of the color. For example, a color with 15%, 0%, 25%, and 36% CMYK represents a color with 15% cyan, 0% magenta, 25% yellow, and 36% black component. The lake bottom black component can be evaluated by visually comparing the lake bottom color with CMYK charts or standard color palettes, and determining the black component according to the percentage found in the CMYK chart. Alternatively other color components can also be used.

[0101] Alternative color scales such as L*a*b* (also known as Lab or CIELAB), X-Y-Z, RGB or HEX can also be used. On the L*a*b* scale, color is measured on three axes: L, a, and b, where the L axis measures lightness. An L value of 100 indicates white and L=0 indicates black. When impurities settle on the bottom 2 of the floating lake 1 and the perceived color of the bottom 2 reaches L=30, the operation of the mobile suction device 42 is activated.

[0102] According to one embodiment, the background color 2 of floating lake 1 is monitored using a monitoring device 24, such as a colorimeter. According to an alternative embodiment, the background color 2 of the floating lake 1 can be determined by means of visual inspection by comparing the background color 2 of the floating lake 1 to a color palette. Bottom color 2 of floating lake 1 can be visualized from the water surface or, in particular when turbidity is high (e.g. more than about 7 NTU), by using a transparent peephole attached to a tube allowing visualization bottom 2 of floating lake 1.

[0103] Bottom 2 of floating lake 1 ordinarily can have a color that provides a pleasing color and appearance to the water in floating lake 1. For example, bottom 2 of floating lake 1 can have a colored material or can be painted with a color such as white, yellow or blue. In an exemplary embodiment, the color of the bottom 2 of the floating lake 1 is measured by a monitoring device 24 (e.g. a colorimeter) of the coordination assembly 20. The perceived color of the bottom 2 of the floating lake 1 can be compared to its real or original color through empirical or analytical methods, such as experience-based algorithms, visual inspection, comparison with color guides, colorimeters, spectrophotometers, and others.

[0104] The operation of the mobile suction device 42 can be activated via the coordination system. In one embodiment shown in Figure 5, the operation of the mobile suction device 42 can be activated by the control unit 22. In other embodiments shown in Figures 6 and 7, the operation of the mobile suction device 42 can be activated manually.

[0105] According to one embodiment, the operation of the mobile suction device 42 is activated before the background color 2 of the floating pond 1 exceeds a predetermined value (for example, before the black background color component exceeds 30% in a CMYK scale (or another suitable color scale)). In one embodiment, the operation of the mobile suction device 42 is activated by the control unit 22 of the coordination assembly 20.

[0106] The background color 2 of the floating lake 1 can be monitored further to determine an end point of the operation of the mobile suction device 42. For example, if the black component of the background color 2 of the floating lake 1 decreases to below the predetermined value, the operation of the mobile suction device 42 can be stopped. Such a value could be, for example, where the black component is 10 percentage units above the value of the black component of the actual background color 2, or 5 units above, or 3 units above. For example, if the original color of background 2 on the CMYK scale is 15%, 0%, 25%, 10%, (the black component being 10%), the value can be set to 20% black, 15% black or 13% black. The value can be predetermined based on the actual background color 2 of floating lake 1 and the desired level of cleanliness of floating lake 1.

[0107] The color of a large floating lake can be monitored at multiple locations throughout the lake. If the floating pond also includes multiple suction devices 42, the bottom 2 can be selectively cleaned in areas to prevent the color of the bottom 2 from exceeding a predetermined value.

[0108] The suction device 42 is preferably a mobile suction device which is capable of cleaning a flexible bottom 2 with a Young's modulus of up to 20 GPa. The mobile suction device 42 moves over the flexible bottom 2 of the floating pond 1, sucking up any sedimented material together with water. The suctioned water and impurities are then sent to a filtration system 44 which separates the impurities from the water. The water sucked in by the suction device 42 can be sent to the system 44 by the use of a pump or a pumping station.

[0109] After vacuuming and filtering, the filtered water can be returned to the floating lake. The return point of filtered water to the floating lake must be designed to minimize the energy costs of pumping such a flow of water.

[0110] Surface debris and oils can be removed from the floating lake by using the defoaming system 50. The defoaming system 50 may comprise floating skimmers or may be installed along the perimeter of the floating lake 1.

[0111] Water must be supplied to Floating Lake 1 to compensate for evaporation, the water that is lost from the Floating Lake for cleanup purposes, and the eventual rate of leakage. Evaporation rates are dependent on weather conditions at the location of the floating lake.

[0112] According to one embodiment, water is supplied to floating lake 1 at a rate that is sufficient to maintain a positive pressure and to replace water lost due to cleaning, leakage and evaporation according to the following equation: Replacement > Evaporation Rate + Cleaning Rate + Leakage Rate

[0113] Replacement rate includes water due to leakage, including losses caused by damage to walls 3 or bottom 2 of floating lake 1. Cleaning rate corresponds to the rate of water that is lost within the water filtration process aspirated. It should be noted that although the filtration system is a closed system, once the water sucked up by the mobile suction device 42 that cleans the flexible bottom 2 is sent to a filtration system 44 and then returned to the floating pond 1, as cycle can comprise water loss due to the backwash process of the filtering system, or if some water is left in the filter media along with impurities, among others. Therefore, the cleaning rate corresponds to the effective water loss due to backwash processes of the filtration system or other losses, such as small losses within the piping network and other systems and equipment.

[0114] Such rates are generally measured in volume of water that is supplied to the floating lake per unit of time.

[0115] Floating lake 1 can be supplied with replacement water from the surrounding body of water. Replacement water from the surrounding body of water can be analyzed to determine whether it can be supplied directly to floating lake 1, or whether it needs to be treated before being supplied to floating lake 1. For example, water replacement can be analyzed using the Platinum-Cobalt color standard to assess whether water can be supplied directly to the floating lake 1. The Platinum-Cobalt scale assigns the color a standard number in the range of 1 to 500+. The Platinum-Cobalt test consists of comparing a 100 mL sample (previously filtered if there is any visible turbidity) with standard colors that have been prepared according to ASTM requirements. In one embodiment, the replacement water for floating lake 1 has a true color of less than 30 Pt-Co. Also, the microbial quality of the replacement water can also be tested before it is supplied to the floating pond 1. In a preferred embodiment, the replacement water contains less than 2000 CFU/mL (colony forming units per milliliter) in order to to be supplied directly to the floating pond 1. If the replacement water has a true color greater than 30 Pt-Co, or if the replacement water from the surrounding body of water has more than 2000 CFU/mL of bacteria, the water is typically pre-treated before being supplied to the floating lake 1. If the water from the surrounding body of water has a true color less than 30 Pt-Co, and less than 2000 CFU/mL of bacteria, the water can be used directly or pre-treated before being supplied to the floating lakes. In other embodiments, water from other sources can also be used as replacement water for floating lakes.

[0116] In another embodiment the floating lake comprises permeable walls. It is possible that the surrounding water has a water quality suitable for recreational purposes, but it is not aesthetically attractive because the bottom is covered with sediment, debris or mud that gives a dark and unpleasant coloring or impression to the body of water. In such a case, a floating pond can be provided where the walls are permeable and allow good quality water to pass through, but the bottom still comprises a flexible solid material. Providing a solid bottom, i.e. one that is stable and continuous and which can withstand the pressures caused by the mobile suction device, for the floating pond allows to provide a pleasant color to the bottom and thus to the water, and allows the device to of suction moves over the bottom, sucking up sedimented organic and inorganic matter. Therefore, in the case where the conditions of the natural or artificial body of water are suitable for recreational purposes, the walls can be constructed of permeable materials that allow to incorporate water directly from the surrounding body of water. In one embodiment, the permeability of the material forming the walls can be selected to allow for a particular permeation rate.

[0117] Other floating lake embodiments comprise systems to control water temperature. For example, the floating lake can be built to maintain a water temperature that is higher than the temperature of the surrounding water. In cold climates, natural waters may otherwise be of adequate quality for recreational use, but may be too cold for most or all of the year for swimming or water sports. In order to allow for a higher water temperature in a floating lake 1, the bottom of the lake can be a darker color, such as dark blue, green, brown, or black. A dark colored background allows solar radiation to heat the water in floating lake 1 to a temperature above that of the surrounding water. For example, the temperature in floating lake 1 may be 4-10°C higher than the surrounding water. The bottom and walls of floating pond 1 can also be constructed of insulating material, further facilitating heat retention in floating pond 1.

[0118] The floating lake system of the present invention can be used for other purposes, such as for industrial cooling purposes, for example, for thermoelectric power plants, data centers, foundries, residential and industrial HVAC systems, solar thermal power plants, paper industries, refineries, nuclear power plants, among other residential or industrial cooling processes. For example, a floating pond system of the invention can be installed within a large body of water in order to provide industrial cooling systems with high quality cooling water at low cost and dissipate heat from the heated cooling water without significantly affecting the properties of the large natural or artificial body of water within which the floating lake is installed. In one embodiment, the floating lake comprises a surface area of from about 50 to about 30,000 m2 per MW of cooling required by the industrial process. Floating lake water generally contains significantly reduced amounts of organic matter when compared to the large natural or artificial body of water in which it is installed, thereby providing a heat exchanger in an industrial process with high-quality cooling water. quality that minimizes bio-dirt and prevents unwanted build-up in heat exchanger tubes that can reduce heat transfer capacity. In one embodiment, the floating pond may be configured to include a supply line operatively connecting the floating pond to an industrial process heat exchanger to supply the heat exchanger with cooling water from the floating pond and a return water line connecting operationally the industrial process to the floating lake to return cooling water heated by the heat exchanger to the floating lake. The cooling water is treated according to the methods of the invention and recycled in the floating lake to achieve a sustainable cooling system over time. EXAMPLES

[0119] The following example is illustrative, and other embodiments exist and are within the scope of the present invention. Example 1

[0120] A floating lake with a surface area of 8 m x 8 m with an average depth of 2.5 m was constructed in order to test the technology of the present application. The floating lake had no permeable walls and a bottom made of a single layer of 1 mm PVC material, where the bottom had a Young's modulus of 3 GPa. The PVC material was thermofused to obtain the floating pond structure, and buoyancy materials were attached to the surface perimeter to provide structural stability and maintain the shape of the floating pond.

[0121] The floating lake was installed in an irrigation pond with a surface area greater than 6,000 m2 that contained substandard water aesthetically unsuitable for recreational purposes. The irrigation pond contained water with high turbidity, a bottom covered with sediment that gave the water a dark color, and a high concentration of organic matter. Key water quality parameters in the surrounding lagoon were measured. The total bacterial count was found to be 300 CFU/mL and the true color measured on the Platinum-Cobalt scale was 35. Therefore, the water from the surrounding body of water was pre-treated before being supplied to the floating lake. Although the water met the bacteriological requirements, it did not meet the true color requirements, and for this reason it was treated before being supplied to the floating pond.

[0122] The floating pond is designed to have a positive pressure when calculating the extra volume needed to feed the floating pond, which is equivalent to having a water level that is above the pond water level. The positive pressure was chosen to be at least 20 N/m2. Since the surface of the floating lake was 64 m2 the volume above the theoretical minimum level was calculated to be 0.128 m3 according to the following equation: Volume above level (m3) > 0.002 m x 64 m2 Volume above level ( m3) > 0.128 m3

[0123] Therefore, as the water level within the floating lake is desired to be 2 mm above the water level of the surrounding water, the total volume of water needed to reach this volume above the level was calculated to be 0.128 m3. In practice, however, it was found that, because of the flexibility of the floating lake walls, that is, the structure separating the floating lake volume from the surrounding water, when the above-level volume was added, the floating lake walls expanded. This expansion caused the actual water level in the floating lake to change to equal the level of the surrounding water, as well as the desired positive pressures.

[0124] The volume above the projected level was 0.5 m3, corresponding to a positive pressure equivalent to a height of water within the floating lake of 7.8 mm above the level of the surrounding water, or a positive pressure of about 76 N/m2. Such positive pressure was maintained by providing the edges of the floating lake with buoyancy devices that compensated for the weight of water.

[0125] A coordination system activated the application of oxidizing agents to maintain an ORP level of 570 mV for 18 hours within 52 hour cycles, and also activated the application of a flocculant composition to prevent the water turbidity from exceeding 5 NTU. The oxidizing agent applied was sodium hypochlorite, added at a concentration of 1 ppm during application. Addition of the flocculant caused the flocculation of impurities which then settled to the bottom of the floating lake.

[0126] A coordination system also enabled the operation of a mobile suction device, by sending a signal to the appropriate operator of the device, and where the mobile suction device was allowed to clean the flexible PVC constructed bottom with a Young's module. of about 3 GPa. The mobile suction device was a specially designed one and comprised a magnetic system that allowed cleaning the flexible bottom. The suction device comprised an inner component which was placed on the inner bottom surface of the floating lake and an outer component which was placed on the outer bottom surface of the floating lake. The internal and external components were magnetically attracted and made it possible to clean the flexible bottom of the floating lake by vacuuming the sedimented material.

[0127] The suction device was activated before the increase in the black component of the background color exceeded 30% on a CMYK scale when compared to the original color. The black component of the background color was assessed by visual comparison with a CMYK scale. The suction device was operated and moved over the bottom of the floating lake, sucking up the sedimented impurities.

[0128] The water sucked in by the suction device was pumped through flexible hoses to a filtration system that was located on the edge of the irrigation pond.

[0129] Water was supplied to the floating lake to maintain positive pressure in the floating lake. Replacement water compensated for the evaporation rate, which was estimated to be 2 mm per day, and a very small water flow corresponding to the cleaning rate. For this reason, the replacement rate was calculated to maintain an above positive water volume in accordance with the cleaning rate and evaporation rate. The replacement water flow was intermittent, and allowed to maintain a positive pressure equivalent to keeping the water level of the floating lake between 5 mm and 1 cm above the surrounding water for more than 50% of the time within 7-day periods.

[0130] As a comparison, the following water quality parameters were obtained from the floating lake and the surrounding water body: Table 1: Water Quality Comparison in Surrounding Water Body and Floating Lake

[0131] The floating lake and method of the Example provided a safe and aesthetically attractive body of water that had better coloration and water quality than the surrounding lagoon.
