New RO desalination pretreatment membrane traps TEP

When desalination.tempurl.host announced in August 2011 that Sumitomo Electric Industries Ltd of Japan had developed a membrane to trap transparent exopolymer particles (TEP) in pretreatment prior to reverse-osmosis desalination, the item attracted a lot of visitors. D&WR, therefore asked Sumitomo for more information about the research and development of this membrane, which is capable of pretreating seawater at a high flux of 10 m/d, enabling low-cost membrane treatment. This article first appeared in the November/December 2011 issue of Desalination & Water Reuse magazine.
