| titleOfInvention | Manufacturing method of composite semipermeable membrane |
| abstract | PROBLEM TO BE SOLVED: To provide a method capable of producing a composite semipermeable membrane having a high solute removal property and a high water permeability without increasing an economical burden and a load on waste liquid treatment. A polyfunctional amine aqueous solution having different concentrations is applied to the surface and the back surface of a microporous support membrane, and then a polyfunctional acid halide solution is applied from the surface of the microporous support membrane. A method for producing a composite semipermeable membrane in which a polyamide separation functional layer is formed on a microporous support membrane, wherein the concentration of the polyfunctional amine aqueous solution applied to the surface of the microporous support membrane is such that the microporous support membrane The manufacturing method of the composite semipermeable membrane characterized by being lower than the density | concentration of the polyfunctional amine aqueous solution apply | coated to the back surface of this. [Selection figure] None |
