Cartridge-type hollow fiber membrane module and method for manufacturing cartridge-type hollow fiber membrane module

A cartridge type hollow fiber membrane module comprising:

• a housing;
• a cylindrical case contained in the housing;
• a hollow-fiber membrane bundle having a plurality of hollow fiber membranes;
• a first potting part that bonds the hollow fiber membranes at at least one end of the bundle of the plurality of hollow fiber membranes such that the hollow fiber membranes are open;
• and
• a sealing component that fixes the first potting part to the cylindrical case so as to be liquid tight but is not bonded to the cylindrical case,
• wherein the first potting part comprises an inner potting part and an outer potting part, wherein the inner potting part and the outer potting part are formed of the same or different potting material, wherein the potting material of the inner potting part and the outer potting part is an epoxy resin, a polyurethane or an epoxy resin in which a filler is added, wherein the sealing component is in contact with the outer potting part, wherein both the inner potting part and the outer potting part are formed in a sealing plane that includes the sealing component, and wherein the sealing plane includes a sealing direction in which the sealing component is squeezed when the first potting part is fixed with the sealing component.
