Conor Braman’s Abstract

Water transport and fouling properties of crosslinked poly(ethylene glycol)

C. Braman, University of Texas at Austin
B. Freeman, University of Texas at Austin

All current ultrafiltration membranes are finely porous and are, therefore, subject to fouling by particulates, organics, and other wastewater components, resulting in a dramatic decline in the water flux (Ho 1999). Our approach to enhancing the severely limited fouling resistance of conventional ultrafiltration membranes is based on coating them with highly water permeable, nonporous, fouling resistant polymers. Crosslinked poly(ethylene glycol) (PEG) is used as the base material for the coatings because it is highly hydrophilic and has shown resistance to protein attachment (Ostuni 2001).

Professor Benny Freeman of the Chemical Engineering Department at University of Texas at Austin and Dr. Ingo Pinnau of Membrane Technology and Research (MTR) are winners of the 2002 Award for Cooperative Research in Polymer Science and Engineering presented by the American Chemical Society’s (ACS) Division of Polymeric Materials: Science and Engineering (PMSE). Dr. Brian Benecewicz, Chairman of the PMSE Cooperative Research Award Committee, announced the award, which has been presented annually since 1992, when it was endowed by a gift from the Eastman Kodak Company to PMSE.

Research accelerates on advanced water-treatment technologies as their use in purification grows

MAIRIN B. BRENNAN, C&EN WASHINGTONConventional water purification is a tried-and-true process that hasn’t changed much in decades: Coagulation and flocculation, sedimentation, sand or gravel filtration, and chlorine disinfection are the customary steps. Wresting fresh water from seawater is also a long-standing technique, especially in oil-rich, water-starved countries where the cost of the energy-intensive process is not an issue.
