Definitions
- the present invention relates to a water purifying device that is placed inside water tanks for human use in urban or rural, commercial or institutional domestic facilities.
- the object of the present invention is to make a device for water purification for human consumption, which eliminates microorganisms and other biological pathogens such as bacteria, viruses and parasites.
- the device eliminates said microorganisms and biological agents by using colloidal silver supported on ceramic pieces of controlled porosity, whose shape is spherical or approximately spherical that are submerged in the water contained in the reservoir and by the contact of the spheres with water. Colloidal silver generates an electromagnetic reaction through the release of silver ions that disinfect water. .
- Said spheres are contained in a support of plastic material which in turn comprises a float element to keep the whole assembly floating on the surface of the water of the tank the assembly has its center of gravity at the bottom to keep the assembly always in it vertical position and the spheres always remain submerged in water.
- water used for human consumption contains pathogenic microorganisms and other biological agents that can cause infections or infestations in humans. This occurs mainly in regions where water is obtained through rustic means from surface or underground sources without proper disinfection or purification, or even in urban areas where disinfection is incomplete or water treated by municipal water supply services is contaminated. during transport, handling and storage.
- Water contaminated with pathogens is the cause of a large number of cases of diseases caused by bacterial infections and parasites; from In these cases there are a high number of people who die, especially children.
- Chlorination requires the handling of hazardous materials such as gaseous chlorine and other chlorine compounds and manual or automatic devices to dose chlorine, some compound thereof such as hypochlorite salts, chlorine oxide or other compounds, or iodine products or derivatives of iodine
- iodine A human error or equipment failure can cause the disinfection to be insufficient or to add an excessive amount of disinfectant that causes a bad smell and taste of the water or that in high doses can cause some degree of intoxication.
- the use of iodine has been proposed to meet the need for this element for the human organism, but this requirement is fulfilled more easily and with better control through the use of iodized salt.
- Ultrafiltration or reverse osmosis membrane-based methods require a pressure feed and reject a part of the water that is enriched with unwanted impurities or that should be treated as wastewater.
- reverse osmosis the balance of salts that naturally dissolve in water is disturbed, which is excessive for usual applications of human consumption. Both ultrafiltration and reverse osmosis membranes require frequent attention and maintenance that make them undesirable for domestic applications.
- Filtration in its different grades requires frequent attention to wash the filter media, energy to pressurize the water to make it pass through the same and controls to prevent the growth of algae and other organisms on the same media.
- granule cartridges In certain devices for domestic use granule cartridges are used, usually of crushed quartz as well as other solids, impregnated with colloidal silver. These devices are very effective due to the biocidal action of silver and its ions, but also require pressure so that water can flow through the granular beds.
- the surface texture of the granules although it is amorphous has very little porosity whereby the amount of silver that can be deposited is limited. In order to solve the current situation, the present invention is created.

- the present invention relates to a device for purification and disinfection of water for human consumption comprising the use of colloidal silver supported on a ceramic substrate of controlled porosity, said substrate is in the form of more or less regular spheres which are housed in a set of very open support chambers that are arranged in a column that stays in an upright position thanks to the fact that at the top end it has a float made of plastic foam.
- the present invention surpasses the devices existing in the state of the art because the ceramic spheres impregnated with colloidal silver are housed in a support of very open plastic material in the form of cages that allows the spheres to move within their respective cavities without touching each other and said support has an upper part comprising a plastic foam float and the center of gravity of the assembly is below this upper part.
- the entire assembly forms a column that retains a vertical position and the impregnated ceramic spheres are kept in the water in a correct position to expose the water to the effect of colloidal silver.
- the housing support comprises several sections made of at least one moisture-stable plastic polymer and suitable for contact with water for human consumption which is selected from among the polyolefins, polystyrene, high impact polystyrene, water-compatible grade polyvinyl chloride for human consumption, acryl nitrile butadiene styrene terpolymer (ABS), polymethyl methacrylate, polyester, Polyethylene Terephthalate (PET), polycarbonate or other thermoplastic polymers or thermosetting polymers compatible with water for human consumption either as a single component or in combinations of more one's.
- ABS acryl nitrile butadiene styrene terpolymer
- PET Polyethylene Terephthalate
- Polymers that are susceptible to degradation by sunlight are formulated with at least one pigment that prevents sunlight from degrading them in applications where there may be exposure to
- pigments are selected from those available in the market and that are compatible with water for human consumption; by way of example and not limitation, the pigments are selected from at least one of carbon black, titanium dioxide, kaolin, natural or precipitated calcium carbonate and other preferably inorganic pigments that do not contain heavy metals potentially harmful to human health. .
- the polymers may or may not contain inert fillers to improve their pro- mechanical features and their stability according to the practices known in the state of the art.
- the shape of the cage-shaped pieces allows them to fit together in multiples that join the top piece that contains the float, which allows several spheres modules to be added to vary the capacity of the device and use different types of spheres
- the set of one or more cages is kept upright because the float is always at the top, above the center of gravity.
- the pieces that make up the assembly are usually white or the natural color of the polymer for applications when the assembly is not exposed to sunlight; but they can be colored in the process of forming with dyes compatible with human consumption to identify if it is a section of spheres with colloidal silver or other materials.
- the assembly that forms the device in the form of a column does not require maintenance during its useful life, the polymers are selected for their zero toxicity, for their absence of taste or smell, for not containing compounds not acceptable for human use; by way of example Bis Phenol A or BPA for its acronym in English, and for being stable by being permanently submerged in water and possibly exposed to sunlight.
- Silver in the colloidal state with which it is impregnated to the ceramic spheres releases silver ions systematically upon contact with water and the microorganisms that it may contain are exposed to said silver ions.
- Water purification is achieved because the ions provided by colloidal silver break the cell wall of microorganisms, interrupt their breathing by affecting their DNA and preventing their reproduction.
- an oxide-reduction reaction an electromagnetic and chemical field is created that generates a hostile environment for viruses, parasites and bacteria.
- the disinfection columns are designed so that the silver ion spheres have maximum contact with the water to increase their efficiency and reduce the time required to carry out the disinfection.
- the columns that make up the disinfection device do not require electrical or other energy, do not require maintenance during their useful life, do not add flavor or smell to the water and lack toxicity.
- the equipment complies with the standards for germicidal equipment and substances for domestic water treatment, such as Mexican standard NOM-244-SSA 1-2008. Bacteriologically, it complies with the Water for Use and Human Consumption standards such as the Mexican standard NOM-127-SSA1-1994 and with the norm NOM-201 -221 -2002 for Water and Ice for Human Consumption Packed and in Bulk.
- cages with spheres with different characteristics can be incorporated into the tower object of this invention, such as activated carbon to absorb odors, colors and residual chlorine, active points with exchange resins ionic to eliminate undesirable metals such as arsenic or high iron content, zeolites to soften water too hard, etc.
- the required amount of raw and wet ceramics mainly alumina, which may contain magnesium, silicon, zirconium oxides and other compounds whose selection does not affect or limit in any way the scope and novelty of the present invention is taken , and is spherically shaped manually. They are dried under controlled conditions of temperature and humidity, between 10 ° C and 80 ° C and more specifically between 18 ° C and 40 ° C and between 5% and 70% relative humidity and more specifically between 10% and 50% of humidity in the air, to reach a humidity in the ceramic of between 0.5% and 20% and more specifically between 0.5% and 10%. They are partially calcined and more layers of raw ceramic are added again and dried and calcined several times to reach the desired size of between 20 and 45 mm in diameter. Finally, the porosity is confirmed by an adsorption process and finally by microscopy inspection. The objective is to achieve a gamma alumina structure due to its high porosity.
- the ceramic spheres are impregnated by a process known in the state of the art with a solution of a soluble silver salt, comprising at least one of silver nitrate, silver thiosulfate, double sodium and silver thiosulfate or other silver salt soluble.
- a solution of the salt or silver salts is prepared at a concentration of between 20% and 50% silver colloidal
- the calcined and also dried spheres are immersed in said solution of a silver salt prepared in accordance with the preceding paragraph, extracted and dried. Subsequently, silver is reduced to elemental silver in a colloidal state by means of a reducing reagent in the absence of air. This operation is repeated 2 to 5 times until the desired thickness and uniformity of the colloidal silver film is achieved.
- the spheres are dried at a decreasing temperature of 350 ° C to 60 ° C and more specifically from 300 ° C to 80 ° C in a reducing atmosphere to fix the colloidal silver impregnation.
- a decreasing temperature 350 ° C to 60 ° C and more specifically from 300 ° C to 80 ° C in a reducing atmosphere.
- the technique applied in the present invention seeks, above all, to increase the porosity of the spheres and the total area of pores, instead of claiming an increase in the hardness and thermal and mechanical resistance of the spheres as is done in various applications, since the working conditions for the present invention do not include high turbulence, high temperatures, thermal shocks or friction between the spheres because the cages containing them prevent contact or shocks between them or with other hard surfaces, and the working temperature is always environment or something inferior to the environment of the place where the water tank is installed.
- the present invention is further distinguished in that the spheres are housed in the plastic cages and the water does not have to pass through a bed of granular material or spheres contained within a container or cartridge as occurs in other devices.
- the device object of the present invention does not require energy of any kind or pressure for the water to pass through the supports that house the spheres. Therefore, the water storage container can be filled with a fixed installation to use municipal water, or with hoses or emptying into it portable containers,
- the device remains in the storage container since its active components do not impart to the water any smell, taste or other undesirable characteristics and also prevents a possible re-infection if it could enter to the container any material that transports pathogenic organisms.
- the device is integrated by means of a hollow piece of plastic 100 in the form of a parallelepiped or cylindrical that contains a piece of foam plastic 122 of closed pore as a float forming a flotation cage.
- the cover 104 and wall 105 of this piece are assembled together by means of ear and groove joints in the shape of a harpoon 101 or pressure joints without necessarily having adhesives.
- the plastic foam may be of any foamable polymer and compatible with water for human use without the material thereof affecting the novelty or scope of the present invention.
- the foam material is selected from at least one of expanded polyethylene, expanded polystyrene, or other foamable and stable polymers before permanent immersion in water.
- an open-walled cage 13 is assembled with pressure joints, which has five open compartments and is provided with spacers that keep the spheres without making contact with each other.
- a ceramic sphere 123 is placed to treat the water.
- the pressure joints are strong enough to prevent the assembly from accidentally disassembling. By preventing contact between the spheres, it is also avoided that they are degraded by erosion or abrasion with the movement of the water when the storage container is filled and emptied.
- the assembly has a buoyancy that makes the upper part on the surface of the water and the cage with spheres is completely submerged, with the assembly in a stable vertical position.
- one or more cages 113 are placed under the first one extending the length of the assembly. Up to five spheres with colloidal silver can be placed in each additional cage to increase the treatment capacity for larger volumes of water. If the number of cages or sphere levels exceeds 4, an additional float section is added in a proportion of one float section for every 4 levels or fraction.
- At least one of the colloidal silver spheres is replaced with at least one sphere impregnated with a disinfectant agent compatible with human consumption, slow and prolonged release.
- a disinfectant agent compatible with human consumption, slow and prolonged release.
- This agent complements the action of silver to ensure the elimination of organisms that take too long to be eliminated by colloidal silver. This mode applies both to the device provided with a single cage and to assemblies of several cages.
- At least one of the spheres is replaced with at least one sphere impregnated with activated carbon or constituted by activated carbon to absorb or adsorb and eliminate undesirable odors and flavors and to remove excess residual chlorine that It is applied in municipal water supply systems and it has an unpleasant taste and smell.

- At least one of the spheres is replaced with at least one sphere impregnated with zeolites to soften water that has a high hardness.
- At least one sphere is replaced, preferably that of the central position of one or more levels and in its place at least one piece consisting of a copper and zinc composition in the form of scales or chips is inserted , in order to cause a synergistic effect with colloidal silver to accelerate disinfection.
- the ceramic spheres receive a punching before cooking to create at least one additional pore of visible size and even in the amount that is physically feasible to occur on the surface.
- spheres impregnated with colloidal silver are combined with spheres containing ion exchange resins, zeolites, disinfectant or extended release disinfectants, activated carbon or copper and zinc parts in any combination. This combination is defined based on the characteristics of the water of each particular locality.
- the plastic polymer parts may contain pigments compatible with water for human consumption of different colors that allow determining both the position of each component within the assembly and the type of impregnation contained in the spheres.
- the float section may have a hollow shape without polymer foam.
- the ceramic spheres can be replaced by pieces with non-spherical shapes, such as cylinders or figures with flat faces or irregular shapes.
