Reverse osmosis (RO) technology has grown extensively in recent years; many new types of membranes are now available, leading to an increase in various applications. Improvements have been made in membrane materials making them more pH, temperature, and chlorine resistant than the traditional cellulose acetate membranes. The ability of membranes to separate simultaneously, or selectively, organic and inorganic solutes from aqueous systems without phase change offers substantial energy savings and flexibility in the design of separation processes. The industrial development of noncellulosic, thin-film composite (TFC) membranes has provided better flux performance and enhanced separations of organics under lower operating pressures than those obtained with cellulosic membranes.
