| titleOfInvention | Manufacturing method of composite semipermeable membrane |
| abstract | PROBLEM TO BE SOLVED: To produce a composite semipermeable membrane having high solute removal property and high water permeability and high durability. At the same time, a composite semipermeable membrane capable of realizing high productivity by a simple and safe method is manufactured. SOLUTION: After a composite semipermeable membrane is produced by forming a polyamide separation functional layer formed by polycondensation of a polyfunctional amine and a polyfunctional acid halide on a microporous support membrane, the composite semipermeable membrane is heated to 50 ° C. or higher. The membrane performance is improved by washing with washing water and then with a peroxosulfuric acid compound under neutral or acidic conditions of pH 7 or lower. [Selection figure] None |
