Title:
SEMIPERMEABLE MEMBRANE SUPPORT FOR PROCESSING MEMBRANE SEPARATION ACTIVATED SLUDGE, FILTRATION MEMBRANE, AND MODULE
Document Type and Number:
WIPO Patent Application WO/2016/148038
Kind Code:
A1
Abstract:
[Problem] The present invention addresses the problem of realizing a semipermeable membrane support that is for processing membrane separation activated sludge, and that has high strength, superior adhesion strength with respect to a frame material, superior adhesion strength between an application surface and a non-application surface of the semipermeable membrane support, and fine adhesiveness with respect to a semipermeable membrane. Accordingly, the present invention addresses the problem of providing a filtration membrane that is for processing membrane separation activated sludge and that has high impact resistance, fine adhesiveness with respect to a frame material, and fine adhesiveness between a semipermeable membrane and a fusion-bonding portion of the semipermeable membrane support, and providing a module formed by using the filtration membrane. [Solution] A semipermeable membrane support for processing membrane separation activated sludge contains a drawn polyester fiber, and a core-sheath polyester composite fiber and an undrawn polyester fiber as a binder fiber.
