Pilot-scale microbial fuel cells using air cathodes were effective in producing electricity while treating wastewater, with power densities of up to 1.5 W/m². The use of air cathodes simplified the system and reduced costs. The results demonstrate the potential of microbial fuel cells for wastewater treatment and energy generation.

Abstract

Key findings

  • Power densities of up to 1.5 W/m² were achieved in pilot-scale microbial fuel cells using air cathodes.
  • The use of air cathodes simplified the system and reduced costs compared to traditional cathodes.
  • The microbial fuel cells were effective in treating wastewater, with removal rates of up to 90% for COD and 80% for ammonia.
