Title:

EXTERNAL CIRCULATION-TYPE HOLLOW FIBER MEMBRANE MODULE

Document Type and Number:

WIPO Patent Application WO/2018/230631

Kind Code:

A1

Abstract:

Provided is 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 (11) is provided with: a hollow fiber membrane bundle (110); a case (112); and a short-path prevention body (114) that blocks flowing of a to-be-treated liquid in a gap between the hollow fiber membrane bundle (110) and the case (112), wherein a first end (110a) of the hollow fiber membrane bundle (110) is fixed in the case (112), and the short-path prevention body (114) is provided to the downstream side of a first port (122) which is a liquid flow-in port in the case (112) so as to project from the inner surface of the case (112).
