2018-079 - Plant-Sediment Microbial Fuel Cell for Wastewater Treatment

Description:
  • Wastewater treatment for high levels of organic matter, including for dairy farms, cattle feed lots, food processing, pulp and paper mills, and petrochemicals

Abstract

USC researchers have developed a novel approach to wastewater treatment by employing a layered structure with microorganisms and granular activated carbon enhanced with graphene oxide. These layers work synergistically to break down pollutants and facilitate electron transfer, boosting the rate of electricity generation and wastewater purification. The inclusion of anodes and cathodes above these layers captures generated voltage, which is stored in an attached battery, creating a self-powered, efficient wastewater treatment solution.

Benefit

  • Self-sufficient and cost-efficient energy generation
  • Capable of storing electricity
  • Straightforward scalability to pilot-scale and full-scale treatment systems

Market Application

The market for sustainable wastewater treatment is growing as environmental regulations tighten and energy costs rise. The integration of Microbial Fuel Cell (MFC) technology presents a dual opportunity: it not only purifies water but also generates electrical energy, enabling the system to be self-sustaining. This innovation addresses the critical need for energy-efficient wastewater treatment solutions, offering significant potential in industries ranging from municipal water management to agriculture and beyond.
