The overarching goal of our study is to develop a novel energy-neutral wastewater treatment technology that could aid in water reuse within a forward operation base, reducing water transport. To achieve this, we developed a microbial fuel cell capable of generating hydrogen peroxide as primary product. This technology takes advantage of the high-energy content of blackwater the microbial fuel cell consumes and converts it into an electrical current that is used to generate significant amounts of hydrogen peroxide. The hydrogen peroxide can have several uses 1 direct treatment of graywater towards reuse, 2 tertiary treatment of graywater andor blackwater, 3 odor control for blackwater, and 4 treatment of blackwater itself for better effluent quality and solids destruction. More specifically, our objectives were to 1 show the feasibility of hydrogen peroxide production from blackwater, 2 achieve hydrogen peroxide production at high efficiency, and3 demonstrate the effective treatment of blackwater at near energy-neutral conditions using a microbial fuel cell.
