Novel Nonporous Nanofiltration Membrane for Wastewater Treatment

EPA Contract Number: 68D50077
Title: Novel Nonporous Nanofiltration Membrane for Wastewater Treatment
Investigators: Wijmans, J. G.
Small Business: Membrane Technology and Research Inc.
EPA Contact: Manager, SBIR Program
Phase: I
Project Period: September 1, 1995 through March 1, 1996
Project Amount: $65,000
RFA: Small Business Innovation Research (SBIR) - Phase I (1995)
Research Category: Water and Watersheds , SBIR - Water

Description:

U.S. industry generates large volumes of wastewater that contains suspended particles, emulsified liquids, dissolved macromolecules, and/or dissolved organic compounds. Nanofiltration can produce dischargeable water from these streams. However, because current nanofiltration membranes are finely porous and only moderately hydrophilic, they are subject to fouling, particularly by particulates and macromolecules.

In this Phase I research program, a novel type of fouling-resistant composite membrane for nanofiltration applications will be developed. The composite membranes will consist of an ultrathin (0.2-0.5 m), nonporous, highly water-permeable layer supported by microporous membrane. This novel membrane will be fouling resistant due to the extremely hydrophilic nature and the nonporous surface of the selective layer. In Phase I, Membrane Technology and Research, Inc., (MTR) will demonstrate the non-fouling properties in MTR's laboratories. In Phase II, the membrane will be fabricated into modules for demonstration in a pilot-scale system.
