In a reverse osmosis membrane of the structure of Loeb\s membrane for use to purify sea-water into plain water, the membrane comprises a skin layer as an active layer and a gel layer to support the skin layer, wherein an improvement of flux, that is the (passing rate of purified water) is achievable

In a reverse osmosis membrane of the structure of Loeb\s membrane for use to purify sea-water into plain water, the membrane comprises a skin layer as an active layer and a gel layer to support the skin layer, wherein an improvement of flux, that is the (passing rate of purified water) is achievable by burying a porous sheet, such as plain-woven cloth or non-woven fabric, in the gel layer.
