This study explores the use of microbial fuel cells (MFCs) for electricity generation and wastewater treatment using wastewater from the Gwagwalada abattoir. The research aimed to assess contamination levels, develop an MFC system, and evaluate its performance over 240 hours. Key parameters analysed are: Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Dissolved Solids (TDS), Total Suspended Solids (TSS), conductivity, and pH, before and after treatment. The MFC was constructed based on established designs and its electrical output voltage and current was monitored throughout the experiment. Results showed a significant reduction in BOD and COD by 69.8% and 68.8%, respectively. The MFC also produced a maximum voltage of 94 mV and current of 0.2 mA. These findings demonstrate that MFCs can simultaneously treat abattoir wastewater and generate electricity, suggesting a promising avenue for sustainable waste-to-energy technologies with potential for further enhancement.
