Abstract
Organics are separated from aqueous solutions by contacting the aqueous solution feed with a first surface of a polymeric membrane selectively permeable to organic components; while maintaining a second and opposite membrane surface at a lower chemical potential than the first membrane surface for said organic components, permeating a portion of the organic components into and through the membrane; and withdrawing from the second membrane surface a mixture having a higher total concentration of organic components than the organic components concentration of the aqueous solution feed stream.
