You may think seawater and brackish groundwater is too salty to be of much use, and in its raw form you'd be right, but scientists at Clarkson University say we need to study this type of water more than ever. With water shortages looming across the world, making water desalination cheaper and friendlier to nature could be a great way to start facing the future's challenges. See the full article for all the details.

Not familiar with the Freman Stillsuit? Didn't bother to read Dune? Well this development by researchers at the UCLA Henry Samueli School of Engineering and Applied Science might just get us a few steps closer to Frank Herbert's water recycling suit.

The Team of researchers have apparently developed a new reverse osmosis membrane that promises to reduce the cost of seawater desalination and waste-water reclamation.

Reverse osmosis desalination basically uses extremely high pressure to force saline or polluted waters through the pores of a semi-permeable membrane. Water passes through, salt-ions and other impurities don't. Presto. Purified recycled water.

Developed by civil and environmental engineering assistant professor Eric Hoek and his research team, the membrane uses a cross-linked matrix of polymers and engineered nano-particles designed to draw in water ions but repel nearly all contaminants. The filter works at nano-scale.

Moreover, because the membranes repel particles that might ordinarily stick to its surface, the new membranes foul more slowly than conventional ones. The result is a process that is just as effective as current methods but more energy efficient and potentially much less expensive.

Initial tests suggest the new membranes have up to twice the productivity — or consume 50 percent less energy — reducing the total expense of desalinated water by as much as 25 percent. Yes, because of the high pressures required, this technology is currently applicable at an industrial level. But what if? Perhaps in the future we'll all be drinking our urine and our feces, just like the Fremen.
