HOLLOW FIBER MEMBRANE MODULE

摘要

PROBLEM TO BE SOLVED: To provide an external pressure type hollow fiber membrane module capable of simultaneously performing drain reverse washing and air-scrubbing.SOLUTION: In an external pressure type hollow fiber membrane module 1 where: both ends of a hollow fiber membrane bundle consisting of a plurality of hollow fiber membranes 2 in which at least one end is open are bonded and fixed at the inside of a cylindrical container 3 by a resin partition wall 4; the resin partition wall 4 consists of an opening side resin partition wall 4a in which the open end part of the hollow fiber membrane 2 is fixed while keeping open and a sealed side resin partition wall 4b in which the end part of the hollow fiber membrane 2 is fixed at a sealed state; and a plurality of through holes are made at the sealed side resin partition wall 4b itself, at least one air introduction port 9 exists at a container side surface between the resin partition walls 4a and 4b of the cylindrical container 3.
