CARTRIDGE-TYPE HOLLOW FIBER MEMBRANE MODULE AND METHOD FOR MANUFACTURING CARTRIDGE-TYPE HOLLOW FIBER MEMBRANE MODULE

摘要

A cartridge-type hollow fiber membrane module is provided with: a housing; a hollow fiber membrane bundle having a plurality of hollow fiber membranes; a first potting section which bonds the hollow fiber membranes together such that the hollow fiber membranes are opened at least at one end part of the bundle of the plurality of hollow fiber membranes; and a sealing material which fixes the first potting section to the housing in a watertight manner. The first potting section includes at least an inner layer potting section and an outer layer potting section, and the inner layer potting section and the outer layer potting section are both formed by a potting agent. The sealing material is in contact with the outer layer potting section, and both the inner layer potting section and the outer layer potting section are formed in the direction of the sealing by the sealing material. Even if steam sterilization is used, leaks and bacterial contamination due to detachment of the potting agent can be prevented.
