Abstract

A method for the treatment of fluid feedstreams comprises the steps of providing at least one wafer (200) comprising a central area (202) providing a plurality of members (18) arranged in a plurality of layers (201) and peripheral support means (203) encompassing the central area, arranged axially in a module (180) having first and second ports (185, 208); a plurality of separate bore fluid chambers (198, 199) generally encompassing the peripheral support means and communicable with the members within the central area, and a plurality of separate bore fluid ports (192, 193) communicable with the bore fluid chambers; directing the feedstream through the first port and over the wafer; and transferring materials between the central area in the wafer and the feedstream. Related methods employ other multi port apparatus (220, 240) as well as wafers (240, 280, 300, 320, 350, 410, 460) for use therein. Treatment of the feedstreams includes contact with layers of hollow fibers (18), non-porous hollow tubes (309), porous hollow tubes (303) coated with membrane material (304 ) and transverse sheet membrane sleeves (360).
