Abstract

An extensive experiments investigation is presented of the continuous flow, membrane ultrafiltration of (I) laundry wastes (containing linear alkylbenzene sulfonate anionic surfactant or linear alcohol ethoxylate nonionic surfactant); (II) shower wastes. The primary laundry waste constituents of concern are surfactants, ortho and polyphosphates, other builders, and oil. Several tight, cellulose acetate (Abcor HFA-180, UOP Type-215, Gulf F-601) and other polymeric (Amicon UM-2, UM-10, PM-10, Millipore PSAL) membranes are studied in terms of surfactant and phosphate rejection. Cellulose acetate membranes show very poor rejection of anionic surfactants in the presence of phosphate and practically no rejection of nonionic surfactants. PSAL (charged) is selected as the optimum membrane in terms of rejections of surfactant, phosphate, and other builders.
