  • HIGH PERMEABILITY FORWARD OSMOSIS MEMBRANE CONTAINING SILICA NANOPARTICLES AND MANUFACTURING METHOD THEREOF
    Publication number: 20220379269
    Abstract: The invention discloses a forward osmosis (FO) membrane containing silica nanoparticles having high permeate water flux and its manufacturing method. The FO membrane containing a plurality of silica nanoparticles comprises a substrate layer made of polysulfone and a polyamide layer disposed on the substrate layer. In the course of manufacturing the polyamide layer on the substrate layer by interfacial polymerization, the plurality of silica nanoparticles with different properties is added into the polyamide layer to obtain the FO membrane containing silica nanoparticles having high permeability and solute selectivity.
