Ultrafiltration membranes for fabrication of protein concentrates

A new version of dry-wet molding of membranes of the UAM type for concentration of curd whey by the ultrafiltration method is proposed. The physicomechanical indexes of the membranes was investigated as a function of the thickness of the filtering layer and concentration of the cellulose diacetate solution. Membranes fabricated from 5% solutions of CDA with a filtering layer thickness of 0.05 mm had the highest selectivity (72%) and filtration rate (43.2·10−3 m/sec) at 20‡C and pressure of 0.1 MPa.
