ABSTRACT:
Methods of controlling the formation of calcium oxalate in aqueous systems are disclosed. The methods comprise adding from about 0.1 to 500 ppm of a water soluble (meth)acrylic acid/allyl ether copolymer to the desired water system. The methods are especially well adapted for use in pulping and paper making systems wherein calcium oxalate is often encountered as a troublesome scale forming compound.
