ABSTRACT:
A hollow fiber membrane module comprising (a) hollow fibers, (b) a fastening member for fixing the ends of the hollow fibers while leaving them open, and (c) a structural member for enclosing and supporting the fastening member, the hollow fiber membrane module being useful in the filtration of water by suction from the surface to the inside of the hollow fibers with intermittent or continuous cleaning of the membrane surfaces of the hollow fibers, characterized in that the hollow fibers comprise a textile fabric containing hollow fibers as the weft and the cross-section of the fastening member perpendicular to the hollow fibers is shaped like an elongated rectangle. In this module, the hollow fibers rarely cohere together into a mass, and the membrane surfaces of the hollow fibers can be efficiently cleaned concurrently with the filtration, so that the loss of the filtering function is minimized.
