Turning desalination waste into a useful resource
(PHYSorg.com Chemistry)

The rapidly growing desalination industry produces water for drinking and for agriculture in the world`s arid coastal regions. But it leaves behind as a waste product a lot of highly concentrated brine, which is usually disposed of by dumping it back into the sea, a process that requires costly pumping systems and that must be managed carefully to prevent damage to marine ecosystems. Now, engineers at MIT say they have found a better way.
