ABSTRACT:
In a hollow-fiber permeability apparatus, a permeating region of a housing contains a bundle of hollow fibers, and materials can selectively permeate through the membranes formed by the permeable walls of the hollow fibers, between a first fluid flowing along the exteriors of the hollow fibers, and another fluid flowing the interiors of the hollow fibers. The apparatus includes at least one first opening and at least one second opening for passing the first fluid, formed in both end portions of the housing; an enlarged cross-section portion formed between the first and second openings and surrounding substantially the whole circumferential surface of the bundle of hollow fibers in the housing; and at least one third opening for passing the first fluid, connected to the enlarged cross section portion, said first and second openings being used as a fluid inlet opening, and the third opening being used as a fluid outlet opening, or the first and second openings being used as the fluid outlet opening, and the third opening being used as the fluid inlet opening.
