Abstract: An external circulation-type hollow fiber membrane module which has a high processing capacity and which is capable of inhibiting a to-be-treated liquid within a case from flowing through a short path and efficiently bringing the liquid into contact with a hollow fiber membrane in whichever direction of a vertical direction, a horizontal direction, etc., the liquid flows. An external circulation-type hollow fiber membrane module is provided with: a hollow fiber membrane bundle; a case; and a short-path prevention body that blocks flowing of a to-be-treated liquid in a gap between the hollow fiber membrane bundle and the case, wherein a first end of the hollow fiber membrane bundle is fixed in the case, and the short-path prevention body is provided to the downstream side of a first port which is a liquid flow-in port in the case so as to project from the inner surface of the case.

Abstract: The present invention pertains to a hollow fiber membrane module (5) for removing gas from an objective liquid or supplying gas to the objective liquid, comprising: a hollow fiber membrane bundle (20); and a collecting member (51) configured to collect first ends (20a) of the hollow fiber membrane bundle (20) while maintaining openings of opened end portions (22a) of hollow fiber membranes (22) of the hollow fiber membrane bundle (20), wherein the collecting member (51) has a coupling portion configured to couple the collecting member (51) to an installation object in a detachable and liquid-tight manner.

Abstract: Disclosed herein is a hollow fiber membrane module provided with a hollow fiber membrane bundle, a case in which the hollow fiber membrane bundle is contained, a fixation part which affixes the hollow fiber membrane bundle within the case and divides the space inside the case into a first space that is outside the hollow fiber membranes and a second space that is in communication with the insides of the hollow fiber membranes, and a partition plate which divides the first space into a first region and a second region.
