ABSTRACT:
A multilayer membrane separator which permits serial and tangential contact of a retentate with a plurality of membranes within the separator. The separator is formed from a plurality of contiguous separator units each consisting of two membrane layers, two retentate layers, a filtrate spacer layer and two adhesive layers. The adhesive layers, in cooperation with a liquid inlet to the separator and a liquid outlet from the separator effect the desired retentate flow and prevent mixing of retentate and filtrate.
