Method for manufacturing hollow fiber membrane module, and hollow fiber membrane module

A method for manufacturing a hollow fiber membrane module, the hollow fiber membrane module comprising:

• 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 or potting parts in which a potting agent is added between outer surfaces of the hollow fiber membranes and inner surfaces of the housing at one end region or at both end regions of the hollow fiber membrane bundle,
• wherein the method comprises:
• providing a sheet-shaped spacer or spacers in a space between the hollow fiber membranes at the one end region or at the both end regions of the hollow fiber membrane bundle;
• and
• adding a potting agent between the outer surfaces of the hollow fiber membranes and the inner surfaces 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 or spacers are embedded,
• wherein the potting agent includes resin, rubber, or elastomer, as a main ingredient,
• wherein the spacer or spacers are a net, a non-woven fabric, a porous sheet, or a film,
• wherein the spacer or spacers are band-formed, and
• wherein the providing includes:
• arranging the hollow fiber membranes in parallel while holding only the one end region of the hollow fiber membranes or only the both end regions of the hollow fiber membranes, on one side of the spacer or spacers;
• and
• forming the hollow fiber membrane bundle as a roll-shaped bundle by rolling the hollow fiber membranes and the spacer or spacers.
