Pushing The Envelope For Wastewater Treatment Energy Savings

Wastewater utilities may soon have a new tool available in their efforts to go green.

Researchers from Washington University in St. Louis have reportedly invented a device that produces electricity from wastewater while simultaneously filtering it for non-potable reuse. The new device is a new take on the microbial fuel cell, which already uses bacteria to convert wastewater to energy, but with an added advantage in that it produces usable water as well.
