Washington University Turns Salt, Dirty Water into Drinking Water

Washington University engineers demonstrate how their biofoam can quickly transform salt water into drinking water. They found a way to transform dirty water or sea water into drinking water using their biofoam and simulated sunlight. The bi-layered biofoam is made of bacteria-produced nanocellulose and graphene oxide. The nanocellulose at the bottom of the bi-layered biofoam acts as a sponge, drawing water up to the graphene oxide where rapid evaporation occurs. The resulting fresh water can easily be collected from the the steam. The researchers say their innovation could be a global game-changer. Photo courtesy of Washington University.
