Title:
METHOD FOR MANUFACTURING A REVERSE OSMOSIS MEMBRANE AND A REVERSE OSMOSIS MEMBRANE MANUFACTURED THEREBY
Document Type and Number:
WIPO Patent Application WO/2013/176523
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing a reverse osmosis membrane, which includes the steps of: forming a polysulfone layer by contacting a solution containing a mixture of two or more solvents of different solubility parameters with one side of a porous membrane support; and forming an active layer on the polysulfone layer, and to a reverse osmosis membrane manufactured thereby.
