Self-reliant Cleaning System Treats Wastewater

Washington State University Researchers Came up with a Method They Hope Will One Day Reduce the Use ofElectrical Energy in Waste Water Treatment
It's a natural self-powered treatment system using organisms called microbial fuel cells.
"If you collect your waste water you can dump it in an area and this water can clean itself over a long term and there's a potential energy in this waste water so what do we do? We collect this energy and speed up the treatment," said Associate Professor of Chemical Engineering, Haluk Beyenal.
They speed up the treatment by adding extra oxygen to the water making the natural cleaners more active. Through this cleaning process energy is released and it can be harnessed as electricity.
The researchers use that electricity to power the aerator that adds oxygen making it a self-reliant cycle system.
The National Science Foundation, U.S. Office of Naval Research and WSU's Agricultural Research Center have all funded this project because of the potential of this system's use in their fields.
