ABSTRACT:
A hollow fiber separatory module for separating fluids includes an annular hollow fiber separatory bundle encased in a pressure resistant shell. A region of the bundle is constricted so that the walls of the fiber are densified. Consequently, compaction of these fibers during operation is reduced. The constricted region is encapsulated by a potting material. Minimization of compaction aids in maintaining a sealing contact between the fibers and the potting material. "O" rings extending from the pressure resistant shell may seal the space between the pressure shell and the fiber bundle. The constricted portion may accommodate the "O" rings so that a pressure resistant shell of uniform outside diameter can be used. The fiber bundle may be constricted by heating, chemical treatment, applying pressure or application of tension during winding.
