Chlorine was historically used as the oxidizing microbiocide at this location as it was considered the most economic alternative. Recent changes in state law, with respect to the storage of chlorine gas, forced the plant to review other oxidizing chemistries, which previously were considered economically unattractive. A trial was run on solid bromine releasing compounds and on activated sodium bromide. Change in corrosion rates and in the amount and type of suspected matter in the water was noted. Improved fouling control and reduction of corrosion rates of admiralty brass and mild steel resulted. Cost comparisons are made.
