90-14: A New Bromine Oxidizing/Nonoxidizing Antimicrobial Combination Product Cleaning Systems

90-14: A New Bromine Oxidizing/Nonoxidizing Antimicrobial Combination Product Cleaning SystemsIn certain water cooling systems, continuous low level application of oxidizing antimicrobials will not provide year round control of algal biofilms in cooling towers. Therefore, these treatment s are often supplemented with periodic additions of non oxidizing, antimicrobials, especially to control seasonal algal biofilms. This report describes a solid combination product that will deliver both oxidizing halogen (BCDMH: bromochlorodimethylhydantonin)

The initial startup of a new recirculating cooling tower system can either result in a substantial reduction in the life expectancy of the heat exchangers and it can cause difficulties in maintaining heat transfer just weeks after startup or
