As National Pollution Discharge Elimination System (NPDES) discharge requirements become increasingly more stringent a biocide that decomposes prior to discharge may become one of the few suitable methods for controlling microbes in cooling water systems. The pH and temperature dependent hydrolysis dibromonitriloproprionamide (DBNPA) was studied over a range of temperatures and pHs (7-8.5) expected for modern cooling water systems. A method for calculating time required for DBNPA decomposition using temperature and pH data for any cooling system is proposed.
