A process for treating wastewater containing an undesired level of suspended organic solids comprising polymeric latex wastes that have been precipitated and coagulated by the addition of an effective amount of lime and phosphoric acid, which comprises (a) adding to the wastewater, subsequent to precipitation and coagulation of said solids, an effective amount of a non-polymeric, cationic flocculating agent comprising a salt of a fatty acid aminoalkyl alkanolamide of the following general structure: [Figure] wherein R is a carbon chain of a fatty acid having from 14-22 carbon atoms, R′is H, or C1-C6 alkyl group, R″is H, or CH3, x is an integer of 1-6, and A is an anion, (b) adding to the wastewater an effective amount of an anionic polymeric flocculant, thereby enhancing the flocculation of said precipitated and coagulated solids and thereafter (c) separating the flocculated solids from the water.
