ABSTRACT:
The relative concentrations of solvent and solute in a solution are altered by a system which includes a cell having chambers separated by a membrane and a means for creating a pressure differential across the membrane. A solution moves through an inlet means around the system and countercurrent and reflux flow and outlet means. The cell may be formed of modular units in such a way as to effect a tapered configuration so that the flow rate is homogeneous around the system.
