New chlorine-tolerant, desalination membrane hopes to boost access to clean water
Date:7/22/2008

make desalination more energy-efficient by developing better membranes, such as those that we are working on, one could reduce the carbon footprint required to produce pure water."

Freeman says McGrath and his research group developed novel materials based on an entirely different platform of membranes than those used today in desalination membranes. These new materials are extremely tolerant to aqueous chlorine so their performance doesn't deteriorate in the presence of chlorine.

"Basically, Dr. McGrath radically changed the chemical composition of the membranes, relative to what is used commercially, and the new membranes do not have chemical linkages in them that are sensitive to attack by chlorine," says Freeman, who holds the Kenneth A. Kobe Professorship in Chemical Engineering and the Paul D. & Betty Robertson Meek & American Petrofina Foundation Centennial Professorship in Chemical Engineering.
