Abstract

Microbial Fuel cells are an alternative source of generating electricity from microorganisms for satisfying the high demand of energy. Because of their high-power output, simple structure and low cost, single-chamber air-cathode MFCs hold great promise for large scale applications in wastewater treatment. In this study an Air Cathode Microbial Fuel Cell (ACMFC) is used simultaneously to generate electric power and treat real mango pulp wastewater. ACMFC was operated in batch mode with four different organic loading namely 1000, 2000, 3000 and 4000 mg/L. The mango pulp wastewater concentration varied in the range from 72,000 mg COD-L to 1, 50,000 mg COD-L. The maximum voltage and maximum surface power density obtained was 1.138 V and 276.078 mW/m2, with an overall chemical oxygen demand (COD) removal of > 95 % and a maximum columbic efficiency (CE) of 30 % (65 Ω resistor). The internal resistance was 62 Ω. These results showed that the air cathode microbial fuel cell produced stable power and a high CE, making it useful for treatment of actual wastewaters.
