Title:
HOLLOW-FIBER-TYPE SEMIPERMEABLE MEMBRANE, HOLLOW FIBER MEMBRANE MODULE, AND FORWARD OSMOSIS WATER TREATMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2016/167267
Kind Code:
A1
Abstract:
Provided is a hollow-fiber-type semipermeable membrane, characterized in that the inside diameter is greater than 250μm but no greater than 700 μm. Even when a high-viscosity draw solution is flowed through the hollow portions of the semipermeable membrane, the decline in the efficiency of forward osmosis treatment can be minimized.
