Low-pressure reverse osmosis drying membrane reinforced by polyester web

This paper describes the preparation of low-pressure reverse osmosis drying membrane from cellulose diacetate (CA)-cellulose triacetate(CTA) mixtures and it's performance. The paper discusses the effects of kind and concentration of solvents and additives, polymerization degree and viscosity of CTA and environmental conditions on the membrane performance, it also presents the test result of the membrane performance.
