Title:

MEMBRANE MODULE, APPLICATION METHOD OF MEMBRANE MODULE AND SUPPRESSION METHOD OF FILTRATION VELOCITY REDUCTION

Document Type and Number:

Japanese Patent JP2023045294

Kind Code:

A

Abstract:

To suppress the membrane filtration performance reduction of a membrane module during storage.SOLUTION: A membrane module 1 has a housing 10, a porous membrane 11 disposed in the housing 10 and a solution 12 filled in the housing 10. The porous membrane 11 has a base material 11a. The base material 11a is hydrophilized by a monomer containing an ester linkage or the polymer of the monomer. The solution 12 has a metal salt.SELECTED DRAWING: Figure 1
