Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1 . A hollow fiber membrane bundle that is convertible into a hollow fiber membrane module with a cross-flow configuration or a hollow fiber membrane module with a counter-current configuration, comprising hollow fiber membranes arranged around a porous support tube, a cured resin tubesheet formed at first end of the bundle, and a cured resin nub formed at a second end of the bundle, wherein: 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 adjacent the first end of the bundle has an annular structure that encapsulates the hollow fiber membranes and the support tube at the first end of the bundle but which does not completely block a first end bore of the porous support tube; the bore(s) of the hollow fiber membranes are open at a face of the nub adjacent the second end of the bundle and the nub adjacent the second end of the bundle has a structure that encapsulates the hollow fiber membranes and the support tube at the second end of the bundle and completely blocks a second end bore of the porous support tube; and the collection tube has a plurality of orifices formed in an outer circumferential surface of the collection tube at positions adjacent to the tubesheet, positions adjacent to the nub, and positions in between the tubesheet and the nub.
