Abstract

This invention relates to novel compositions and a novel process for removing toxic resin acids and their derivatives from water and waste water effluent. In one specific aspect, the invention pertains to novel compositions and a novel process for removing toxic resin acids from effluent of pulp and paper mills. A composition for treating effluent comprising: (a) a water soluble nonionic polyalkylene ether containing lower alkyl groups in the alkyl chain and having a molecular weight exceeding 50,000; and (b) an ionic water-soluble polymer having a molecular weight exceeding about 10,000.
