摘要： When forming a separating functional layer containing crosslinked polyamide, by carrying this out in the presence of 1) carboxylic acid ester with a total of 8 or more carbons, or 2) carboxylic acid, it is possible to provide a composite semipermeable membrane which, while still maintaining a high rejection rate, is more outstanding in its water permeability than hitherto.

摘要： The present invention relates to a composite semipermeable membrane which is characterized in that it is a composite semipermeable membrane in which there is formed by polycondensation on top of a microporous support membrane a crosslinked polyamide ultra-thin membrane layer from polyfunctional amine, polyfunctional acid halide and polyfunctional acid anhydride halide, and the flow of water permeate at an operating pressure of 0.3 MPa, a temperature of 25° C. and a pH of 6.5 lies in the range from 0.8 to 4.0 m3/m2.day and, furthermore, the percentage humic acid removal is at least 98%; a method for the production thereof; and a water purification method employing same. With the composite semipermeable membrane obtained by means of the present invention it is possible, in particular, to recover drinking water at a high rate by permitting passage of silica and preventing deposition thereof at the membrane surface while selectively separating/removing the pollutants and trace quantities of harmful materials and their precursors, etc, contained in the raw water in water treatment plants.
