Abstract
A method and composition for flocculation and separation of suspended solids from an industrial process stream containing suspended solids is provided. The method includes the steps of adding to the stream a water-in-oil-in-water emulsion polymer in an amount effective to flocculate the suspended solids and separating the flocculated solids therefrom. The composition is a water-in-oil-in-water emulsion of a water-soluble polymer in which the continuous phase is an aqueous solution of a water-soluble salt.
