Title:
EXTERNAL PRESSURE-TYPE HOLLOW-FIBER MEMBRANE MODULE
Document Type and Number:
WIPO Patent Application WO/2019/216148
Kind Code:
A1
Abstract:
The present invention provides a hollow-fiber membrane module that, during filtration operations, is less likely to cause fouling of a hollow-fiber membrane, enables stable filtration, and has excellent washability of the hollow-fiber membrane. In this external pressure-type hollow-fiber membrane module, a first-end side and a second-end side of a hollow-fiber membrane bundle 60 are fixed, by means of an adhesive, together with an inner wall surface of a cylindrical housing 10 or an inner wall surface of a cap. The part on the first-end side fixed by the adhesive has a plurality of raw water introduction holes 65 that are formed so as to penetrate said part in the thickness direction. The filling rate of the hollow-fiber membrane bundle 60 is 40-70%. The length (L) from the first-end surface side to the second-end surface side of the hollow-fiber membrane bundle 60 is not more than 2 m.
