Water, Water Everywhere…but maybe with Nanotechnology?

Abstract:
The Nanomagnetics' approach exploited a water purification process called Forward Osmosis.

Basically, the way this works is that if you had a bag made of a nanoporous membrane that more or less served as a filter and filled that bag with these magnetic nanoparticles and some clean "draw" water, and then put the bag into contaminated water, the dirty water would be pulled through the membrane into the bag by osmotic pressure exerted by the difference in concentration between what's outside the bag and what's inside. Then you could just pick up the nanoparticles in the bag with a magnetic field, and voila...clean water...and you could use the bag again.
