Description

^«SELF-CLEANING WATER RESERVOIR AND PURIFICATION SYSTEM" This invention consists of a self-cleaning water reservoir and purification system that provides the means required to improve water storage conditions in water tank-type reservoir facilities, ensuring that the water consumed is free of contamination and thereby considerably improving the consumption conditions available to users. In general, water tanks are square or cylindrical storage facilities equipped with lids and are manufactured in fiber glass, cement, reinforced plastic and other less conventional materials. Such facilities require half-yearly or annual cleaning in order to ensure that the water supply will be maintained in adequate conditions for consumption. As is well known, there is always the possibility of small animals and/or insects (cockroaches, lizards, among others) entering or accidentally falling into a water tank that is not tightly closed. A case in point is that of rats, which normally inhabit sewers. Should a rat fall into a water tank, it will remain alive for up to six days before dying. During this period, the rat will be urinating and defecating into water that is to be supplied to consumers through the internal distribution system of homes or other establishments. The practice of cleaning water tanks is rarely carried out by a considerable percentage of the population which, seemingly unconcerned about the state of the water supply, regularly consumes contaminated water, thus triggering a series of illnesses in the human organism. Based on studies and research, it is well known that afflicted with diseases caused by poor quality water and that 60% of all children and adults admitted to hospitals and emergency rooms suffer from maladies related to poor quality water. By way of illustration, the medical profession has long been aware of the fact that drinking a considerable quantity of water per day enhances the effectiveness of the colon in its role within the blood renewal system. This is a process known in medical terms as hemopoiesis or the formation of blood cells. This is made possible by activation of the folds of the mucous membrane found in the colon. The result is improved absorption of the nutritional elements in the foods we ingest and, consequently, improved generation of renewed blood. When the colon does not function effectively, the human being experiences fatigue, falls ill and has a great deal of difficulty in recovering. The adult colon is approximately 2.5 cm in length and absorbs the nutritional elements that the body receives. If the colon is clean, the food that we ingest several times a day will be completely absorbed by the folds of the colon mucous membrane and will be used by the organism as the foundation for generation of renewed blood. Particularly in large cities, governments have generally adopted measures to ensure that the population receives treated water. However, when the water reaches residences and various types of other establishments, it is often stored in poorly maintained water tanks and, consequently, loses the quality developed at the source of supply. Another factor of importance that deserves underscoring is that no matter how much water distribution companies treat the water supply, it is frequently pumped through aging pipe systems to homes and other establishments. In many cases, these distribution systems are 60 or 70 years of age, when the World Health Organization recommends that piping system should be substituted every 30 years. Obviously, there is very little possibility of this occurring. For this reason, the water that reaches final consumers is often characterized by high levels of bacteria and considerable impurities, caused mostly by crusts that have formed within pipe system, chemical residues, sand, mud, etc. Another factor that further aggravates the situation is that the piping is commonly installed in public areas parallel to sewage systems, separated in many cases by no more than 30 cm to 70 cm. With this in mind, one can easily conclude that, with the passing of time, leaks in the sewage system can easily contaminate water lines. Water treatment and distribution companies assume responsibility for the quality of the water supply up to water meters. From that point forward, the owner or user of the property assumes responsibility for maintenance and water quality. When a water tank is cleaned, it is first emptied and then washed down with chemical products, including chlorine. This is a highly corrosive product that reacts with the cement lining of water tanks (particularly those manufactured in fiber cement or asbestos) . The result is the release of small particles of asbestos into the water supply which are then absorbed by the human organism while bathing, brushing teeth, preparing food, coffee, teas, etc . In the case of plastic water tanks, the greatest inconvenience is found in the fact that, when exposed to the sun, these tanks release contaminating substances, since plastic is a petroleum-based product. Most people demonstrates very little concern with the state of water storage facilities, since water tanks are generally located in very hard-to-reach places, and do not give adequate attention to the importance of improving the quality of the water they consume nor to the possibility of improving the health of both children and adults. With this in mind, the petitioner has developed a self-cleaning storage system that also purifies water before distributing it into the local supply system. At the same time, the reservoir itself is lined internally with materials that combat formation of microorganisms that can be prejudicial to human health. The external walls of the storage unit possess a series of magnetic elements that have the function of aligning molecules and breaking down clusters, aimed principally at increasing the vibrations and rotation of the water molecules, while improving the oxygenation and conservation of water over a longer period of time. In order to perform these functions, the reservoir is preferentially spherical, elliptical, or wedge-shaped taking the form of a ultifaceted prism, though other generic shapes not specified here can also be utilized. The reservoir is equipped with an access lid, support base and intake and outflow ducts, as well as the respective valves, float and other necessary equipment. This innovative reservoir has the advantage of being self-cleaning as a consequence of the characteristics of its construction or, in other words, not only does the physical format contribute to the level of turbulence when water is drawn off by the internal system, the materials used in the walls of the reservoir consist of fiberglass and polyester, with an internal coating composed of "Gel Coat", ultraviolet and silver colloid. Each of these elements has specific importance when viewed in the overall context of the unit: a. Fiberglass: though fiberglass is already used in some reservoirs, it should be stressed that it avoids chemical and radioactive water contamination, maintains temperatures at ideal levels since fiberglass is also considered a thermal material and contributes to avoiding molecular and mineral alteration of the water; b. Polyester resin: extracted from distilled petroleum asphalt, aromatic/aliphatic solvents, pigments and minerals that do not contaminate the water; c. Gel Coat: maintains internal walls smooth, avoiding accumulation of dirt and corrosion caused by the chemical products used in water treatment, such as chlorine; d. Ultraviolet : To avoid penetration of sunrays, principally when the reservoir is exposed to the open air and sun; e. Silver colloid: a powerful bactericide that combats possible bacteria and fecal coliforms that originate in the piping of external networks and inevitably make their way into the reservoir. The external walls of the reservoir include a series of tablet shaped magnets that have the function of breaking down, separating and aligning molecules when found in cluster formations. Without this process, it would be difficult for these molecules to fulfill their function of conducting and transporting nutrients to cells in the human organism. This avoids morphological deformation and aids in the processes of reproduction and multiplication, improving immunological systems and avoiding disease. The magnetic field formed in the self- cleaning reservoir helps to protect the water against formation of bacteria cultures. The reservoir includes a dechlorination unit installed at the point of water intake from the supply network. The purpose of this device to avoid the inflow of excess chlorine since, in only about three hours, this product is transformed into gas, evaporates and leaves the water unprotected. It was with this in mind that the magnetic field was developed. The base of the reservoir includes a dirt collection system which is designed to collect all of the heavy dirt that sinks naturally to the bottom, including such impurities as sand, mud and crust from the piping and chemical residues. The dirt flows into the collector which, in turn, is connected to the bathroom toilet flush valve. As a result, every time the flush valve is used, the dirt gathered in the collector device is automatically eliminated. To complete this description and make it possible to better understand the characteristics of this invention and its practical utilization, we have appended a series of drawings aimed at exemplifying the unit's various functions . Figure 1 is a schematic drawing of the self-cleaning reservoir, with a blowup of the structural walls of the unit . According to the illustrations cited above, this invention, entitled "SELF-CLEANING WATER RESERVOIR AND PURIFICATION SYSTEM", has the following characteristics: the reservoir (1) is preferentially in the spherical, elliptical or wedge-shaped format in a ultifaceted prism, though other generic shapes not specified herein can be adopted. It is equipped with an access lid (2) and support base (3), as well as intake (4) and outflow (5) ducts and the respective valves (6) . Based on these characteristics, the reservoir (1) is self-cleaning and the material used in its construction includes a structure composed of fiberglass walls (7) coated internally (T) with a layer of polyester resin (8), Gel Coat (9), ultraviolet (10) and silver colloid (11) • The external surface (Tl) of the reservoir walls has a series of tablet-like magnets (12) that have the function of breaking down and aligning water molecules when such are found in clusters. This is important because cluster formations make it difficult for the molecules to fulfill their function of conducting and transporting nutrients to the cells of the human organism. The reservoir (1) has a dechlorination unit (13) installed at the intake point (4) of the water from the supply network. This device is designed to avoid entry of excess chlorine. The support base (3) of the reservoir has a dirt collection unit (14), designed to collect all of the heavy dirt that sinks naturally to the bottom, including such things as sand, mud and crust from the piping, as well as chemical residues. This dirt is channeled into the collector which has an outflow valve (15) connected to the flush valve of the toilet system (V) . As a result, whenever the toilet is used, the dirt gathered in the collector is eliminated, thus avoiding the possibility of developing bacteria cultures in the collector. The outflow of water from the reservoir uses piping (16) that is independent of the collector (14) , making it possible to distribute treated water through the supply network (17) . Consequently, the self-cleaning reservoir has an enormous advantage over other systems available on the market, since it generates higher quality water for consumption in homes and other establishments, contributing to improved quality of life, with enhanced health and hygiene. The invention can be produced in a variety of forms, all of which generate the same practical applications. It should be understood that the terminology used here has the objective of providing a description and should not be seen as a limiting factor.
