A method is described for improving the removal of toxic resin acids and fatty acids from pulp and paper effluent and from other streams containing resins and fatty acids. The addition of an anionic material, such as albumin, gelatin, alginate or alginic acid prior to clarification with conventional or state of the art cationic coagulation clarification or retention will improve the removal of resin acids and fatty acids.
