Abstract:
1. A hollow fiber membrane separation device, the device arranged for counter-flow and comprising: a cylindrical-shaped pressure casing having a feed fluid inlet port, a non-permeate fluid outlet port, and a permeate fluid outlet port; a cylindrical-shaped cartridge arranged coaxially with the casing, the cartridge having a tubular-shaped inner core member and a plurality of hollow fiber membranes arranged in a bundle about the inner core member; the inner core member of the cartridge being in communication with the feed fluid inlet port of the casing, one end of the inner core member being perforated and terminating in a tubesheet; each hollow fiber membrane of the bundle having an open end toward a permeate fluid outlet end of the casing and a sealed fiber end toward a non-permeate fluid outlet end of the casing; a baffle arranged about the outer periphery of the bundle to force a feed fluid flow traveling between the open fiber end and the sealed fiber end to travel parallel to the hollow fiber membranes and in a direction counter to a fluid flow inside each hollow fiber membrane; the tubesheet encapsulating the open fiber end of the bundle, the other end of the hollow fiber bundle being the sealed fiber end.
