An organic oxidizing biocide, bromo-chloro-dimethylhydantoin, was compared with chlorine for relative ability to decompose several phosphonates and triazole used as corrosion/scale inhibitors in water treatment formulations. These compounds are often used in air conditioning systems associated with cooling towers. The effect of the oxidizing biocide on the microbiology of several cooling systems was evaluated by the use of plate counts or dip stick enumeration. If oxidizing biocides are used in cooling systems, care should be taken to use phosphonates that are relatively resistant to oxidation. Concentration of the biocide should not be in excess of 1 ppm to avoid decomposition of components of the scale/corrosion inhibitor formulation.
