Abstract
Objectives. 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 and/or blackwater, (3) odor control for blackwater, and (4) treatment of blackwater itself for better effluent quality and solids destruction.
Key findings
- The MFC consumes and converts blackwater into an electrical current that generates hydrogen peroxide.
- The hydrogen peroxide can be used for direct treatment of graywater, tertiary treatment of graywater and/or blackwater, odor control for blackwater, and treatment of blackwater for better effluent quality and solids destruction.
- The technology has the potential to reduce water transport and aid in water reuse within a forward operation base.
