A membrane assembly for fluid separations consisting of a compact stack of alternating layers of membrane with layers of fluid conducting materials. The assembly consists of a simplified and improved plate and frame apparatus. The stacked assembly may be placed into a pressure containment device consisting of standard pipe with standard methods of closure. Internal fluid conducting passages are formed from cutouts in the stacked layers thereby greatly simplifying the manufacture and assembly of large diameter fluid separation devices using membranes to effect the fluid separations. The fluid pathways are such that the membrane assembly is particularly efficient in separation.

A device for the separation of two or more different materials comprising: a pressure vessel adapted to contain fluids under pressure, means for admitting feed fluid to be separated to said vessel, means for removing residue from said vessel, means for removing permeate from said vessel, at least one compact stacked assembly within said vessel adapted to be pre-tested and comprising a plurality of elements disposed in superposed relationship, said elements including separator membranes, distribution zones for providing lateral flow of feed fluid to be separated across the active faces of said membranes, and permeate carrier elements abutting the opposed faces of the membranes to carry away permeate, means for providing a wide range of sizes and for precluding misalignment which includes said elements in said stacked assembly having registered edge notches at two spaced-apart points, one of said registered edge notches forming a feed channel for feed fluid to be separated and the other of said registered edge notches forming a residue collection channel, said distribution zone being in fluid communication with said feed and residue collection channels at said registered notches, and said elements also having registered internal apertures forming a permeate collection channel which is in fluid communication with said permeate carrier elements, said stacked assembly being disposed between said means for admitting and said means for removing.
