Patent number: 8567612Abstract: 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.Type: GrantFiled: June 29, 2010Date of Patent: October 29, 2013Assignee: NanoH2O, Inc.Inventors: Christopher James Kurth, Jeffrey Alan Koehler, Meijuan Zhou, Brett Anderson Holmberg, Robert Leon Burk
