ABSTRACT:
A method of continuous separation of dissolved materials employs two membranes, each disposed in its own fluid-tight chamber. An aqueous feed solution containing organic material is passed in contact with a recirculating flow of organic extractant which receives selected dissolved organic material. The extractant is then passed over a second membrane, the other side of which is supplied with a stripping solution for further selective recovery of the desired material. During recirculation the organic extractant is passed through an aqueous separator. However, extractant treatment for organics removal therefrom may also include methods other than the use of a second membrane and a stripping solution.
