Abstract
An improved method for treating alkaline industrial process waters to control the growth and deposit of microorganisms which comprises adding to such waters a combination of a water-soluble anionic polymeric dispersant having a molecular weight not greater than 50,000 and hypobromous acid, said hypobromous acid having been produced by contacting a solution containing: PA1 (a) a water-soluble inorganic bromide, and PA1 (b) an anionic polymeric dispersant with a chlorine containing oxidant chosen from the group consisting of an inorganic hypochlorite salt, hypochlorous acid, and chlorine.
