Abstract
HOBr solution for biocidal treatment is produced by electrolysis of mixed chloride/bromide solution. The chloride: bromide molar ratio is greater than 4:1. The molar ratio and rate and period of electrolysis can be selected so as to result in high yield of HOBr, preferably over 90% of theory, and little or no residual HOCl. The process can suitably be carried out by recirculating the mixed halide electrolyte through an electrolytic cell for a time appropriate to achieve the desired result, and then discharging the solution to a receiving system.
