Modified Thin-Film Nanocomposite Membrane of TheForward Osmosis Using By Modified Zeolite

Forward osmosis (FO) is an increasing membrane separation technology with the many advantage. The water flux performance of current FO membranes is mostly limited by the internal concentration polarization (ICP) of solutes in their porous substrates .The current study investigated the use of nanocomposite substrates for controlling ICP and thus improving FO water flux. Polyethersulfone - nanocomposite (PESfN) substrates were prepared via phas einversion by incorporating porous zeolite nanoparticles in polyethersulfone .The PESfN substrate showed improved surface porosity and hydro philicity. A thin film composite (TFC) polyamide active layer was prepared by interfacial polymerizationon the PESfN substrate,and there sulting TFC-PESfN membrane showed significantly enhanced water permeability compared to the TFC membrane prepared on a conventional polyethersulfone substrate
