2 Cooling Water Treatments Receive Patents
August 2, 2011
Two more U.S. patents have been awarded to Timothy Keister, CWT, FAIC, who is the chief chemist at ProChemTech International Inc., Brockway, Pa.
- "Flow Through Graphite Electrode and Containerless
Cell" discloses the material and method of manufacture for electrolytic
bromine generator cells as used in the ElectroBrom, MiniBrom, and SSBrom units
manufactured by ProChemTech for controlling micro-organism growth in cooling
tower water. Electrolytic bromine is a green technology in that no hazardous or
toxic chemicals are used in the process, and the electrolytic bromine, when
used at 0.5 to 1.0 mg/l in the cooling water, degrades after use to harmless
bromide ion as found in seawater at 65 mg/l.
- "Colorant Tracer for Cooling Water Formulations" discloses the colorant, formulations and method of use for a colorant tracer to control cooling water treatment product dosage. The technology, marketed as BlueTrace manual control testing and BlueTrak automatic online control, uses spectrophotometers at 620 nm to measure the concentration of colorant in the treated water.
