ABSTRACT:
A wafer (100) providing transverse sheets of semipermeable membrane (21). Such wafers include peripheral support means (101) defining a generally cylindrical ring and having inside (104) and outside surfaces (105), a plurality of transverse sheet membrane sleeves (16) carried within the peripheral support means, and a plurality of baffle plates (110, 125) carried between adjacent membrane sleeves. Apparatus (60) for the separation of a fluid into permeate and retentate portions comprises at least one transverse sheet membrane wafer (100), vessel means (61) providing a first port (68) for receiving the fluid, a second port (69) for withdrawing the retentate and a third port (70) for withdrawing the permeate, means for compressing (74) the wafer within the apparatus, and permeate chamber means (72) within said vessel, separate from the feedstream and the retentate by the means for compressing (74) and peripheral support means (101). Separate methods are also provided for the manufacture of the wafers as well as for the separation of fluid feedstreams into permeate and retentate portions.
