An antimicrobial composition prepared by mixing an aqueous polymer-ammonium salt formulation comprising one or more polymers and one or more ammonium salts with a chlorine source in a molar ratio of chlorine (as Cl2) to ammonium ion of about 1:10 to about 10:1 and sufficient alkali to result in a composition which exhibits effective antimicrobial activity in a industrial water system being treated.
