ABSTRACT:
A fluid mixture separation membrane element (10) includes elongated hollow pressure-resistant non-permeable transport arteries (12) and a plurality of flexible hollow fibers (14) of semipermeable material having internal flow channels (20). The hollow tubular transport arteries (12) have exteriors (18) and interior flow passages (16). Each hollow fiber (14) has spaced opposite end portions (22, 24) and an elongated tubular portion (26) extending between and interconnecting the opposite end portions (22, 24). The opposite end portions (22, 24) of each hollow fiber (14) are attached by either an adhesive (28) or another suitable mechanism to the tubular transport artery or arteries (12) so as to provide flow communication between the internal flow channels (20) of the hollow fibers (14) and one of the interior flow passages (16) or the exteriors (18) of the hollow transport arteries (12). The flexible hollow membrane fibers (14) have thin walls, small diameters and short lengths such that they can provide a densely-packed extended surface area for enhanced separation of a raw fluid mixture into permeate and retentate portions without creation of such backpressure as would result in reduction of the forces driving the separation process. The hollow fibers (14) can be arranged in various forms, such as individual hollow fibers, bundles of hollow fibers, knitted or wefted textiles, and fiber carpets or rugs. The fiber membrane elements (10) are fabricated by using various types of rotating, winding, and swinging methods.
