Membrane separation and wastewater treatment

Membrane technology has attracted much attention from scientists and engineers in recent years as a new separation process. Its applications are used for controlled relase of drugs, gas separation, hemodialysis, industrial processes and wastewater treatment. This article reviews membrane separation in these applications with special emphasis on reverse osmosis (RO) and ultrafiltration (UF), the two processes widely used for water and wastewater treatment. For both processes, the process descriptions, membrane materials, device configurations, applications for wastewater, along with advantages and limitations are discussed.link_to_subscribed_fulltex
