Novel Nonporous Fouling-Resistant Composite Nanofiltration Membranes and Membrane Separation Systems for Wastewater Treatment.

Abstract

Navy ships generate large volumes of wastewater, which to meet new regulations, will require treatment prior to overboard discharge. Treatment by nanofiltration can produce dischargeable water, but all current nanofiltration membranes are finely porous and only moderately hydrophilic. They are, therefore, subject to fouling by particulates, resulting in a dramatic decline in the water flux. Development of fouling-resistant membranes will improve nanofiltration systems by lowering capital costs, reducing energy consumption, and decreasing system down-time.
