Halogen-based biocides have been used for many years in cooling water to control microbial fouling. Potential problems associated with the misapplication of halogen-based biocides in cooling water are increased corrosion, degradation of scale and corrosion inhibitors, and poor storage stability. Advances and innovations in this field have led to products in which the oxidizing effects and degradative properties of the halogen are stabilized. This provides much more effective control of the microbial fouling process in cooling water shile being less aggressive towards other system components. Methods used to measure increased effectiveness of stabilized halogen biocides are presented and discussed in this paper. Laboratory and field experiments of a stabilized halogen antimicrobial control program are detailed. Performance of this stabilized halogen program for Legionella pneumophila control is also discussed.
