Apparatus (60, 105, 115, 130, 150) for the separation of a fluid into permeate and retentate portions. Such apparatus provides a plurality of hollow fiber separation wafers (10), each wafer comprising a mat (25) of hollow fibers (18) arranged chord-wise of the wafer; and peripheral support means (11) encompassing the ends (19) of the hollow fibers and having inside (14) and outside (15) faces and upper (12) and lower (13) faces. The apparatus further includes vessel means (59, 121, 149) providing a first port (66, 132, 155) for receiving the fluid, a second port (69, 136, 158) for withdrawing the retentate and a third port (68, 135, 156) for withdrawing the permeate; means for compressing (73, 104, 111, 138, 161) the plurality of wafers in axial alignment; and permeate chamber means (71, 148, 164) within the vessel, separate from the feedstream and the retentate by the means for compressing and the support means. A method for the separation of fluid feedstreams into permeate and retentate portions includes the steps of feeding the fluid into a module containing a plurality of hollow fibers arranged chord-wise in parallel sheets, each sheet being oriented perpendicularly with respect to the longitudinal axis of the module; providing separate chambers for the permeate, communicating with the lumens of the hollow fibers, and for the retentate, communicating with the areas between the hollow fibers; and removing the permeate and retentate from the module.

A method for the separation of fluid feedstreams into permeate and retentate portions comprising the steps of: providing a separate module having a feedstream inlet and a retentate chamber, connected by a plurality of wafers in axial alignment, each said wafer comprising a mat of hollow fibers arranged chord-wise of said wafer and in a plurality of flat layers, each said layer having a plurality of straight hollow fibers in adjacent, parallel alignment with axial flow space therebetween; and continuous peripheral support means encompassing the ends of said hollow fibers; directing said feedstream through said feedstream inlet over said wafers and axially therethrough; separating said feedstream into a permeate portion, which permeates said hollow fibers and flows radially through said peripheral support means into said permeate chamber, and a retentate portion, which passes around said hollow fibers and axially into said retentate chamber; and removing said permeate and said retentate from said module.
