  • METHOD FOR MODIFYING COMPOSITE MEMBRANES FOR LIQUID SEPARATIONS
    Publication number: 20120031842
    Abstract: A method for modifying the surface of nanofiltration (NF) and reverse osmosis (RO) composite membranes, comprising placing said composite membrane in a suitable vessel having a feed inlet opening and a permeate outlet opening, feeding an aqueous solution of one or more monomer(s) and free radical initiator into said vessel through said inlet opening, generating transmembrane pressure, thereby creating a flux across said membrane into said permeate outlet opening and causing said monomer(s) graft polymerize in the presence of said free radical initiator onto one face of said composite membrane.
