HOLLOW-FIBER MEMBRANE MODULE PROCESS FOR PRODUCING HOLLOW-FIBER MEMBRANE MODULE AND HOLLOW-FIBER MEMBRANE UNIT EQUIPPED WITH HOLLOW-FIBER MEMBRANE MODULE

摘要

A hollow fiber membrane unit capable of increasing the throughput by preventing the permeation rate of the membrane from decreasing and appropriately setting the membrane area per unit volume, and a hollow fiber membrane module for use in such hollow fiber membrane unit. A hollow fiber membrane sheet in which a hollow fiber membrane is arranged in a sheet form or a laminate thereof and a water collecting member in the form of a housing for holding the hollow fiber membrane sheet or a laminated body thereof, Wherein the hollow fiber membrane module is filled with a porous resin (potting resin) and has an opening for fixing the hollow fiber membrane sheet laminate, wherein the water collecting member has a thickness of 20 mm or less along the sheet out- The ratio of the total cross-sectional area of the hollow fiber membrane on one side where the openings are formed is at least 45%.
