Innovative Membrane Technology Promises Access to Clean Water

Here's another approach to providing drinkable water, a commodity that much of the world doesn't have access to. In this case, it's about a desalinization method, meaning salty water can be made drinkable in a fairly low cost way. 

By applying an ultra-thin, electrically conductive coating on top of the membrane and then charging the surface with low voltage, the salt ions and other charged species in the water are pushed away from the membrane surface, reducing scaling and fouling.
