Abstract
A membrane separation cell is described comprising a stack of supporting members each supporting a membrane on each of its opposite faces and defining a permeate compartment therewith, and separating members interposed between the membranes of adjacent supporting members and defining feed solution compartments therewith. The separating members are plates formed with passageways connecting the feed solution compartments in series through the stack such that the feed solution flows through each feed solution compartment in an inward direction across one face of the separator plate and in an outward direction across its opposite face. The membrane supporting members are plates each formed with an outer rim having passageways for conducting the permeate from the permeate compartment in parallel out of the stack.
