Abstract
The present specification provides a method for manufacturing a water-treatment separation membrane, the method comprising: preparing a porous support; forming a polyamide active layer on the porous support by using an interfacial polymerization of an aqueous solution comprising an amine compound and an organic solution comprising an acyl halide compound; and coating a coating solution comprising a random copolymer comprising the monomers represented by Chemical Formulae 1 to 3 onto the polyamide active layer, in which a content of the random copolymer is 0.5 wt % to 2 wt % based on a total weight of the coating solution, a water-treatment separation membrane manufactured by using the same, and a water treatment module comprising the water-treatment separation membrane.
