Abstract

Key findings

  • The pilot-scale tubular plant-microbial fuel cells showed stable power generation over a period of 12 months, with an average power density of 20-30 mW/m².
  • The fuel cells demonstrated a high removal efficiency of chemical oxygen demand (COD) and total suspended solids (TSS) from the wastewater, indicating their potential for wastewater treatment.
  • The plant-microbial fuel cells performed better than traditional microbial fuel cells, with a higher power density and removal efficiency, due to the synergistic effects of plant roots and microbial activity.
