Traditional treatment programs for recirculating systems using strong oxidizing biocides often result in elevated general corrosion rates. A novel mild oxidizing biocide system that provides superior microbial control of cooling systems at considerably lower corrosivity has been introduced. The novel biocide is produced on site using dedicated feed equipment to convert a strong oxidizer, sodium hypochlorite, into a mild oxidizer that selectively targets mesophilic bacteria and algae without detrimental corrosive side-reactions. Typical performance improvements of cooling systems using this program include a substantial reduction in azole corrosion inhibitor feeds, increases in cycles of concentration, and decreased cleaning frequencies for condensers.
