Title:
EXTERNAL PRESSURE TYPE HOLLOW FIBER MEMBRANE MODULE
Document Type and Number:
Japanese Patent JP2019195800
Kind Code:
A
Abstract:
To provide a hollow fiber membrane module which hardly causes fouling on a hollow fiber membrane upon the filtration operation and can perform stable filtration operation and has preferable washing property of the hollow fiber membrane.SOLUTION: The first end part side and the second end part side of a hollow fiber membrane bundle 60 are fixed together with an inner wall surface of a cylindrical housing 10 or an inner wall surface of a cap with an adhesive. A fixation part by means of the adhesive of the first end part side has a plurality of raw water introduction holes 65 which are penetrated and formed in a thickness direction. In an external pressure type hollow fiber membrane module, a charging rate of the hollow fiber membrane bundle 60 is 40 to 70% and a length (L) from the first end surface side to the second end surface side of the hollow fiber membrane bundle 60 is 2 m or less.SELECTED DRAWING: Figure 1
