COMPARING |

| Comparing these TECHNOLOGIES There are currently two chemical-free alternates commonly used to control cooling tower and process water circulation systems to eliminate the existence of algae, bacteria and viruses in the water, and preventing scale buildup and corrosion, in order to reduce the system maintenance and operational problems, and, to eliminate the environmental pollution resulting from the use of chemicals. In many areas today, the use of chemicals has been banned through local code restrictions and one or the other of these alternative methods of water purification and control has been chosen to solve those problems as well as to reduce the operating costs of the water circulation systems. It has been reported that the use of chemicals has been banned by the EPA in new construction in some cities causing developers to choose an alternate water management system. Although both IONIZATION and Ozonation eliminate biological growth in water circulation systems the technologies are not similar in how the two actually effect biocide, (killing the algae, bacteria and viruses). Ozone is a very short life span oxidizer that kills the organisms immediately on contact, but it has no residual effect as it lasts only a few minutes in water before changing state. IONIZATION, on the other hand, has a very long residual oxidizing life span, kills the organisms slowly, and is effective in the water even when the circulation system is idle. In actual use, the Ozone injected into a partial sidestream of water loses its oxidizing power before much of it mixes with the main flow of water so it rarely affects some of the critical elements of a circulation system, leaving pumps, condenser tubes, etc., unprotected from algae and bacteria growth. Another failure with Ozone treatment is the fact that its powerful oxidation properties will actually stimulate corrosion. Oxidation and corrosion are in effect the same thing, and since Ozone is a very strong oxidant, it has a strong tendency to initiate corrosion and ultimately cause pitting in metal fittings and components in a circulation system. Although ozone treatment does leave a thin layer of metal oxides on metal surfaces preventing further corrosion, that oxidized surface slightly deters heat transfer, the primary function of a water cooling system. Ozone does not loosen existing scale nor prevent sodium or silica based scale from forming, as does IONIZATION of specific metals used in ION Generation Systems. However, it is effective in stopping biological growth which, when allowed to live, hides and adheres to existing scale, so the effect of the treatment limits scale buildup to some extent. An IONIZATION System polarizes the suspended minerals and compounds in the water and DOES cause existing scale and corrosion to release and break up, dissolving them into solution which is then removed from the circulating water via filtration. Unlike Ozonation, the IONIZATION of a copper alloy acts as an algaecide. a bactericide and a virucide and its dissolved copper alloy minerals have a long residual effect, are not affected by varying temperatures, and actively kill biological growth wherever it lives in a water circulation system. Copper alloy IONs actively control algae, bacteria, and virus even during periods when the circulation system is not in use. The resulting dissolved particulates are also removed from the water via filtration. The ION Generation System produces the necessary purification and cleansing results required in maintaining an efficiently operating and thoroughly clean water circulation system unlike any other type of system in use. By integrating water purification, scale and corrosion release and dissolution, and particulate removal through filtration, the ION Generation System eliminates chemicals, stops the water wasted during "blowdown", eliminates most of the maintenance procedures required, and reduces the circulation system's annual operating costs dramatically.
