Abstract
A process for preparing a semi-permeable membrane includes providing an aqueous phase comprising a polyfunctional amine monomer, covering a surface of a porous support membrane with the aqueous phase, applying an organic phase comprising a polyfunctional acyl halide monomer, a phosphorous containing compound and a co-solvent, and allowing the polyfunctional amine monomer and the polyfunctional acyl halide monomer to perform an interfacial polymerization reaction to form a polyamide thin film composite layer. The presence of the co-solvent together with the phosphorous compound in the organic phase potentiates the effect of the phosphorous compound so that the water flux is increased without substantially sacrificing the salt rejection.
