Membrane fouling by natural organic matter (NOM) is an inevitable phenomenon and one of the greatest hurdles in membrane filtration processes employed to treat surface water for potable water production (Bolton et al. (2006); Lahoussine-Turcaud et al. (1990)). A great deal of effort has been made to understand the nature of the membrane fouling, to develop mitigation strategies, and to improve the filtration performance (Howe and Clark (2002); Lee et al. (2001)). Previous studies have provided valuable insights on the factors that affect membrane fouling, including type of membrane, property of membrane material, process configuration, operating condition, water quality parameters and cleaning strategies, and the effect of membrane material, in particular, has been the focus of many past studies in which the surface properties of the membranes were correlated to interaction with foulants in the feed (Childress and Elimelech (1996); Evans et al. (2008)). Previous studies, however, have dealt almost exclusively with polymeric membranes, while alternative membrane materials have been receiving increasing interest.
