  • Water treatment system
    Patent number: 5480564
    Abstract: The present invention comprises an improved method and apparatus for treating water in heat exchange systems. The present invention automatically and inexpensively provides an effective chemical to process water systems at times and in proportion to the need for water treatment in such systems. When used in evaporative cooling systems, the present invention adds the treatment chemical to the system via the make-up water. The make-up water acquires a substantially constant concentration of treatment chemical as it is passed through a device containing a treatment chemical. The constant concentration of chemical is achieved by dividing the make-up flow into two streams within the device, saturating the smaller of the two streams with chemical, and re-mixing the two streams. The biocide agent used in the preferred embodiment of the invention is prilled elemental iodine.
