Document Type and Number:
WIPO Patent Application WO/2014/204218
Kind Code:
A2
Abstract:
The present invention relates to a method for manufacturing a water-treatment separation membrane having improved salt removal rate and permeation flux characteristics and to a water-treatment separation membrane prepared by the manufacturing method, the method comprising the steps of: forming an aqueous solution layer containing an amine compound on a porous support; bring into contact an organic solution containing an acyl halide compound and a first organic solvent with the aqueous solution layer to form a polyamide active layer; and coating a second organic solvent having lower volatility than the first organic solvent on the polyamide active layer.
