Chapter 12

Design of Advanced Membranes and Substrates for Water Purification and Desalination

James Economy, Jinwen Wang and Chaoyi Ba,    Center of Advanced Materials for the Purification of Water with Systems, Department of Materials Science and Engineering, University of Illinois at Urbana-Champaign, Urbana, IL, USA

To be useful in a desalination process, membranes must exhibit a number of characteristics such as high water flux, high salt rejection, mechanical stability, resistance to fouling, and low cost. A number of polymer materials such as cellulose acetates, thin-film composite (TFC) polyamides, cross-linked poly (furfuryl alcohol) and sulfonated polyethersulfone have been investigated for desalination. Of these, cellulose acetates ...
