HOLLOW FIBER MEMBRANE MODULE

PROBLEM TO BE SOLVED: To provide a module which reduces a mechanical damage caused by a continuity fluid and maintains a stable performance in a high functional membrane module. SOLUTION: In a hollow fiber membrane module which possesses a hollow fiber membrane bundle comprised of a plurality of hollow fiber membranes 1, a bundle case 9 housing the hollow fiber membrane bundle 1, seal fixing parts comprised of a partition resin 4 sealing with an adhesive both the ends of the hollow fiber membrane bundle, opening parts 3 of the hollow fiber membrane in which both the end surfaces of the hollow fiber membrane are opened through the partition resin, and a case opening for continuity of a fluid on the side surface of the bundle case, an opening ratio of constituting raw fiber, a fiber pitch, a fiber diameter and an initial tensile strength are predetermined for a net-shaped material 2 involving the hollow fiber membrane bundle 1 for reducing the fluctuation and the press of the hollow fiber membrane bundle 1 caused by the continuity fluid.
