Abstract: A hollow fiber membrane bundle useful for manufacturing a wide variety of hollow fiber membrane modules having different flow configurations includes hollow fiber membranes arranged around a porous support tube, a cured resin tubesheet formed at first end of the bundle, and either a cured resin nub or a cured resin tubesheet formed at a second end of the bundle. The bore(s) of the hollow fiber membranes are open at a face of the tubesheet adjacent the first end of the bundle. The tubesheet has an annular structure that encapsulates the hollow fiber membranes and the porous support tube at the first end of the bundle but which does not completely block a bore of the porous support tube, wherein the collection tube has a plurality of orifices formed therein at least at positions adjacent the nub.

Abstract: A rotary valve includes a rotary component configured to rotate about an axis of rotation thereof. The rotary component includes a plurality of fluid openings formed at an exterior surface thereof with each of the fluid openings forming a fluid inlet or a fluid outlet into one of a plurality of fluid passageways formed through the rotary component. The rotary component further comprises a valve body rotatably receiving the rotary component therein. The valve body includes a five fluid ports formed therethrough with each of the fluid ports configured to be selectively aligned with one of the fluid openings of the rotary component depending on a rotational position of the rotary component relative to the valve body to allow the rotary valve to operate as a five-way switching valve.
