WSU researchers found a more sustainable process to treat wastewater that uses less energy than current methods. 

Wastewater is composed of organic materials, which bacteria consume to clean the water. Through this process, the bacteria create electrons, said WSU postdoctoral researcher Abdelrhman Mohamed.

The wastewater provides food for the bacteria but lacks the electron acceptor that is necessary. However, these
