Graft Polymerization as a Route to Control Nanofiltration Membrane Surface Properties to Manage Risk of EPA Candidate Contaminants and Reduce NOM Fouling

Project Information

Award Amount:$349,000.00
Dollars Leveraged:$0.00
Start-End Dates:5/1/03-4/30/06
Description:We propose to develop new nanofiltration membranes by modifying the surface structure of commercial membranes at the molecular level via UV-assisted graft polymerization of hydrophilic monomers using our patented method. Our objective is to transfer major successful developments from biotechnology applications to environmental protection. New materials will be developed that offer high flux compared to commercial membranes (by improving membrane porosity), enhanced rejection of inorganic anions and ionizable organic compounds (by controlling membrane pore size distribution and surface charge), and enhanced ability to resist fouling by natural organic matter (NOM) by reducing adhesion. We seek to understand the characteristics of natural organic matter accumulated on membrane surfaces both in terms of resistance to flow (which can influence the cost of membrane processes) and its affects on the transport and rejection of charged solutes.
