The article discusses the different processes of membrane separation. It explains that membranes may be made from physical solids, homogenous films, heterogenous solids, solutions, asymmetric structures and liquids. Some of those processes discussed are electrodialysis, reverse osmosis and nanofiltration, and microfiltration. It notes that gas-separation membranes separate gases from other gases while pervaporation is a separation process in which a liquid mixture contacts a nonporous permselective membrane.
