Spiral type separation membrane element |
| abstract |
PROBLEM TO BE SOLVED: To provide a spiral separation membrane element which is superior in oxidation resistance than conventional ones and is less likely to have a reduced salt rejection. SOLUTION: The spiral separation membrane element of the present invention has a porous structure in which a supply-side channel material and a skin layer containing a polyamide-based resin obtained by interfacial polymerization of a polyfunctional amine component and a polyfunctional acid halogen component are supported. A composite semipermeable membrane formed on the surface of the body, and a permeate-side channel material, wherein the polyfunctional amine component includes N, N′-dimethylmetaphenylenediamine, and the permeate-side channel The material is characterized by a porosity of 40-75%.
