Abstract

The accumulation of scale in an aqueous system is inhibited by the addition of a composition comprising a copolymer of maleic acid or anhydride and styrene sulfonic acid, an organic phosphonate such as aminotri- (methylene phosphonic acid) or hydroxyethylidene diphosphonic acid, and an aminocarboxylate chelating compound such as nitrilotriacetic acid or ethylenediamine tetraacetic acid, or their water soluble salts.
