OUTSTANDINGLY CHLORINE RESISTANT HIGH-FLOW-RATE WATER-TREATMENT SEPARATION MEMBRANE AND PRODUCTION METHOD FOR SAME

摘要

A water-treatment separating membrane includes a polyamide active layer formed on a porous support. When the polyamide active layer is dyed using a 5% aqueous solution of Rhodamine B, at least a curve pattern formed by connecting two or more arcs is formed in at least a partial area of the polyamide active layer.
