Abstract
A method for manufacturing a hollow fiber membrane module, the hollow fiber membrane module including: a hollow fiber membrane bundle including a plurality of hollow fiber membranes; a housing configured to contain the hollow fiber membrane bundle; and a potting part in which a potting agent is added between an outer surface of the hollow fiber membranes and an inner surface of the housing at both end regions or at one end region of the hollow fiber membrane bundle, wherein the method including: providing a sheet-shaped spacer in a space between the hollow fiber membranes at the both end regions or at the one end region of the hollow fiber membrane bundle; and adding a potting agent between the outer surface of the hollow fiber membranes and the inner surface of the housing at the both end regions or at the one end region of the hollow fiber membrane bundle such that the provided spacer is embedded, wherein the potting agent includes resin, rubber, or elastomer, as a main ingredient, and wherein the spacer is a net, a non-woven fabric, a porous sheet, or a film.
