    摘要: The flux of a composite reverse osmosis or nanofiltration membrane having a polyamide discriminating layer is enhanced in a one-step process in which the discriminating layer is treated with ammonia or certain alkylamines. It is possible to control both rejection rate and flux of the membrane as well as convert reverse osmosis membranes into nanofiltration membranes.

    摘要: A composite membrane and method for making the same, comprising a porous support and a crosslinked polyamide surface. The subject membrane provides improved flux and/or rejection rates. The subject membrane is further capable of operating at lower operating pressures. The subject method includes reacting a polyfunctional amine with a polyfunctional acyl halide to form a polyamide. The method includes the step of contacting a phosphorous containing compound with the polyfunctional acyl halide prior to and/or during the reaction between the polyfunctional acyl halide and a polyfunctional amine. The subject process is easily adapted to commercial scale manufacturing processes and is particularly suited for making nanofiltration and reverse osmosis composite membranes.
