摘要: RO membranes using chlorinated water as a feed stream maybe protected from damage by the chlorine with a protective layer including reactive nitrogen which forms chloromines on the surface of the membrane that reduce chlorine penetration. This protective layer also provides substantial anti-fouling capabilities, whether used with a chlorinated or unchlorinated feed stream because the chloramines are anti-bacterial. Although chlorine is lost in use, the anti-fouling layer or coating can be recharged with additional chlorine without damaging the discrimination layer. The anti-fouling layer or coating may be advantageously used with Thin film composite, TFC, membranes for use in forward and reverse osmosis may include nanoparticles, monohydrolyzed and/or di-hydrolyzed TMC, and/or alkaline earth alkaline metal complexes or other additives.

摘要: An interfacial polymerization process (IFP) for preparing a highly permeable TFC RO membrane by contacting on a porous support membrane for IFP, a polyfunctional acyl halide monomer and a polyamine monomer and recovering a highly permeable thin film (TFC) reverse osmosis (RO) membrane. At least one of solutions may contain nanoparticle additives which may release ions into solution and at least one of the solutions may contain additional ions from a second additive. The presence of the nanoparticle additives during IFP may increase the hydrophilicity and/or permeability of the recovered membrane compared to a control membrane. The presence of the additional ions from the second additive may also increase the permeability of the recovered membrane.
