New membrane makes fresh water from sea and sewage feasible

Posted by Trish Riley, August 1, 2010

Researchers at Yale University have developed a custom membrane that can clean and purify water from oceans, salty ground water or sewage water with far less energy input than currently is required to do a similar job.

The membrane may be a big step forward in reaching the goal of reliable and affordable sources of fresh water. Finding sustainable sources of clean drinking water is a major global challenge, especially in most of the developing world. The need is apparent in both urban areas, due to growing population and demand, and rural regions, where sometimes scarce water supplies are quickly drying up.
