Process Cleans Wastewater, Generates Electricity, Desalinates Seawater

A team of researchers from the U.S. and China modified a microbial fuel cell - a device that uses naturally occurring bacteria to convert wastewater into clean water producing electricity - so it could desalinate salty water. The new process cleans wastewater, generates electricity, and removes 90 percent of salt from brackish water or seawater.
