Abstract

2057872 9014310 PCTABS00002 An effluent treatment process which comprises the steps of: a) adding a coagulant to the effluent to concentrate the organic material therein; b) treating the thus concentrated organic material with a mixture of a cationic polymer or copolymer in the presence of an anionic surfactant, a monionic surfactant or both; and c) separating the organic material from the effluent by flotation.
