Abstract
A method of manufacturing a water-treatment separating membrane includes forming an aqueous amine solution layer on a porous support, and forming a polyamide active layer by dropping droplets of an organic solution including an acyl halide compound on the aqueous amine solution layer. A water-treatment separating membrane manufactured by the same also is provided.
