Abstract

This invention is directed to the treatment of aqueous systems, and specifically to the inhibition and removal of scale and solid deposits in industrial water systems. The invention comprises the use of less than a stoichiometric amount of an inhibitor composition comprising at least one acrylic polymer, at least one water-soluble polymer derived from maleic acid or its anhydride, water-soluble organic phosphonates, and at least one water-soluble chelating agent. This inhibitor composition is added to the water in the systems in amounts ranging from about 0.01 to 600 parts of the inhibitor composition per million parts by weight of the water.
