The present invention relates in general to water management systems, and, more particularly, to cooling and/or recirculating water management systems that eliminate the need for chemicals, bleed water, and labor to maintain recirculating water systems at peak efficiency. This results in: (1) up to a 40% savings in energy consumption; (2) the elimination of chemical treatment costs; (3) the elimination of blowdown water and sewer costs; (4) the elimination of labor to clean/restore heat exchange equipment; and (5) greatly extended equipment life. The water management systems of the present invention also result in the elimination of environmental pollution from chemical bleed, and personnel protection against waterborne diseases, such as Legionella.
While evaporative water cooling for heat exchange systems (e.g., cooling towers, chillers, compressors, heat exchangers, HVAC systems, etcetera) and heat rejection processes is the most efficient cooling method, it is also the most aggravating to maintain because of scale, corrosion, algae, bacteria, biofilm, and sludge. The present invention eliminates the above-identified problems using physics instead of conventional, environmentally problematic chemistry by synergistically utilizing a centrifugal separator, a germicide generator, and a magnetic field generator.
Water management systems and associated components have been known in the art for years, and are the subject of a plurality of patents including, for example: U.S. Pat. No. 8,223,495 entitled “Electronic Device Cooling System,” U.S. Pat. No. 5,145,585 entitled “Method and Apparatus for Treating Water in a Cooling System,” U.S. Pat. No. 4,764,283 entitled “Method and Apparatus for Treating Cooling Tower Water,” U.S. Pat. No. 4,519,919 entitled “Method and Apparatus for Magnetically Treating Fluids,” U.S. Pat. No. 4,202,847 entitled “Apparatus and Method for Cooling Water Especially in Cooling Towers,” U.S. Pat. No. 4,172,786 entitled “Ozonation of Cooling Tower Waters,” U.S. Pat. No. 4,153,559 entitled “Water Treatment Device and Method for Manufacturing Same,” U.S. Pat. No. 3,997,635 entitled “Method and Device for Evaporative Cooling,” U.S. Pat.

U.S. Pat. No. 8,223,495 appears to disclose cooling systems for providing cooled air to electronic devices. The systems can include large storage tanks or waste treatment systems to improve the efficiency of the plant and reduce impact on the environment.
U.S. Pat. No. 5,145,585 appears to disclose a method for treating water in a cooling system that includes a cooling tower and heat exchanger. The method includes the steps of removing water from the main cooling water circuit, serially subjecting the water to magnetic treatment, treatment with ozone, filtering with a centrifugal separator, and then returning to the main cooling water circuit. Underflow from the centrifugal separator is filtered with a bag filter, and the filtered water returned to the magnetic treatment step. The pH of the water may be controlled by regulating the production of dry air supplied to the ozone generator.
U.S. Pat. No. 4,764,283 appears to disclose an apparatus and method of reducing agglomeration of fluids consisting of the vigorous agitation of the liquid by a double opposed vortex nozzle and the passing of the liquid through a magnetic field. One of the opposed nozzles may have ozone gas forced through it for treating sewage. The apparatus and method may also be used to treat cooling tower water.
U.S. Pat. No. 4,519,919 appears to disclose an apparatus for and method of magnetically treating flowing fluids that includes a housing into which a fluid stream is directed and in which the stream is divided into a plurality of separate flow paths. Each of the flow paths within the housing is subjected to a monopolar magnetic influence and a baffle configured to induce turbulence in the flow path to insure exposure of all of the fluid in the path to the monopolar magnetic influence. The separate flow paths are at least partially recombined to a single flow path and discharged from the housing.
U.S. Pat. No. 4,202,847 appears to disclose a water cooling tower and method which provides for both wet and dry cooling within the same vertical space and significantly reduces the discharge of water particles out of the tower. Water is deposited on one side of each of a plurality of trickler plates and flows downwardly under the influence of gravity substantially undisturbed as a low speed film. Air flows at low speed by natural draught in a substantially undisturbed path on the other side of each of the plates.
U.S. Pat. No. 4,172,786 appears to disclose a continuous ozone injection into water that circulates between a cooling tower and heat exchanger with heavy scale deposits inhibits formation of further deposits, promotes flaking of existing deposits, inhibits chemical corrosion and controls algae and bacteria.
U.S. Pat. No. 4,153,559 appears to disclose a device for the magnetic treatment of water and other liquids, having a pair of concentric tubular casings which are spaced from each other so as to form an annular treatment chamber. The inner casing contains an elongated magnet having two or more longitudinally spaced poles, and the outer casing is made of a magnetic material which serves to concentrate the magnetic lines of force within the annular chamber. The inner casing is supported within the outer casing by means of elastic, non-magnetic sleeves which are positioned over opposite ends of the inner casing and compressed between it and the inner surface of the outer casing so that the treatment chamber is rendered fluid-tight and the inner casing and magnet are prevented from shifting longitudinally with respect to the outer casing. The device is manufactured by pressing resilient end caps on opposite ends of the magnet and pressing this assembly into the inner casing, inserting the inner casing in the outer casing and then wedging the sleeves between them.
U.S. Pat. No. 3,997,635 appears to disclose a method and a device for preventing formation of mist by the discharge of moistened air from an evaporative cooler, primarily a cooling tower of the multi-layer type, comprising a contact body composed of a plurality of layers forming between themselves gaps passed by water to be cooled and atmospheric air which is moistened and heated by contact with the water in counter-current or cross-current flow. Under certain conditions as when the temperature of the atmospheric air is so low, when the moistened and heated air is discharged to the atmosphere and cooled to the low temperature of the latter, the moisture contained in the discharged air will be condensed and precipitated in the form of mist to the extent it exceeds the saturation point of the air. Such precipitation can be avoided by mixing the moistened air prior to its escape into the atmosphere with preheated dry air. The invention provides a novel method and device for producing such preheated dry air by causing part of the introduced atmospheric air to pass through gaps of the contact body shut off from the flow of water passing through the body, whereby this air is heated without change of its moisture content by heat exchange with the warm water flowing through adjacent gaps. The moist air current from the gaps wetted by the water flowing through them and the dry air current from the gaps not accessible to the water provided an air mixture which, even when discharged into the relatively cold atmospheric air and thereby cooled to the low temperature thereof, will not contain so much moisture that the saturation limit is surpassed and condensed vapor precipitated. Means are also disclosed to adjust the ratio of the gaps open to the water flow to the gaps shut off from said flow so as to reduce the number of dry gaps in which no cooling effect is produced to the minimum necessary for avoiding mist formation.
U.S. Pat. No. 3,669,425 appears to disclose a water cooling tower which comprises a blower opening into the bottom of the tower for introducing or blowing air into the tower. A continuously walled wet decking arranged in a spiral mounted above the air inlet port and having a large number of regularly spaced projections arranged in an inclined checkerboard or step like pattern to control the counterflowing air and water in the tower. A spray tree for introducing water into the vessel is mounted above the wet decking and a mist eliminator is mounted above the spray tree. The mist eliminator is also constructed in the form of a continuously spirally wound vertical wall with adjacent surfaces of the eliminator wall being separated by a multiplicity of step like baffles.
Chinese Patent Number 201392109 appears to disclose a closed type cooling tower, which includes a fan arranged at the top of the tower, a water-catching tank arranged at the bottom of the tower, a medium inlet and a medium outlet, a heat exchanger coil arranged in the tower and a spraying water-distributing system, wherein two ends of the heat exchanger coil are respectively communicated with the medium inlet and the medium outlet, the spraying water-distributing system is connected to the water-catching tank through a cycling water pump; moreover, the spraying water-distributing system is also provided with a plurality of nozzles, wherein the heat exchanger coil is formed by a capillary; as the capillary is characterized by large heat exchange area, thin wall, good thermal conductivity, uniform heat exchange, and the like, by adopting the capillary as the heat exchanger coil, on one hand, the heat exchange effect of the cooling tower can be improved, on the other hand, under the condition of equal heat exchange requirement, the heat exchanger coil which is formed by the capillary can be designed to be smaller, thereby leading the volume of the cooling tower to be smaller.
Chinese Patent Number 2906512 appears to disclose a water-saving and environment-friendly cooling tower, which relates to a cooling device for cooling the circulating water. An air intake shutter of air cooler is symmetrically arranged on the sidewall of the cooling tower body, an air cooler is arranged close to the air intake shutter, a distributing pipe in the air cooler inside is connected with a circulating water intake pipe, an outlet pipe of the air cooler is connected with a water distributor, a lower catchment tank of the air cooler is connected with a circulating water outlet pipe by a bypass pipe. The air cooler is arranged above a water collector, the water distributor is arranged between the two air coolers. The utility model is water saving, the air cooler is used to precool the circulating water, the cooling load of the filler segment and the quantity of the evaporated water are decreased. The air becomes hot and dry when going through the air cooler and the humidity of the hot wet air, which can reduce the humidity ratio of the hot and wet air after being exchanged in the filler layer, and the water fog generated at the top of the tower is avoided or reduced, which is favorable to environmental protection.
Chinese Patent Number 1844824 appears to disclose an environment-friendly water-saving cooling tower, wherein the side wall of the tower is symmetrically distributed with wind inlet shutters of air cooler; the inner side that is near to the shutters is distributed with an air cooler; the water distributing tube at the inner side of air cooler is through to the water inlet tube of cycle water, while the water outlet tube of air cooler is through to the water distributor; the lower water tank of air cooler via the branch tube is through to the reflux tube of recycle water; the air cooler is above the water collector; the water distributor is between two air coolers. The invention uses an air cooler to pre-cool the cycle water, to reduce the load, the steam amount, and the water consumption.
While the above-identified patents do appear to disclose various water management systems and associated components, their configurations remain non-desirous and/or problematic inasmuch as, among other things, none of the above-identified systems appear to provide a water cooling/recirculating management system that synergistically utilizes a centrifugal separator, a germicide generator, and a magnetic field generator.
