ABSTRACT:
A fluid separation module made up of a cylindrical shell having an outlet end and an enlarged inlet end. A bundle of hollow fiber membranes positioned in the shell extend through a cast tube sheet positioned in the enlarged inlet end of the shell. A flexible, imperforate sleeve is positioned in the shell surrounding the bundle of hollow fiber membranes, with one end of the sleeve being secured to the fiber bundle adjacent to the tube sheet and the other end of the sleeve being secured to the inner surface of the cylindrical shell at the enlarged end at the end thereof to leave a retroflexed, intermediate portion of the sleeve extending down the shell between the shell and the bundle of hollow fiber membranes. A fluid entering the inlet end of the shell inflates the flexible sleeve to occupy all free space between the fiber bundle and the shell and thereby force all of the fluid to pass through the bundle of hollow fiber membranes.
