MICROBIAL POWER: ELECTRICITY GENERATION FROM DOMESTIC AND AGRICULTURAL WASTEWATERS USING MICROBIAL FUEL CELLS
Abstract:Microbial fuel cells have been shown to produce electricity from a variety of defined compounds and domestic wastewater. Here it is shown that power can also be generated from other complex wastewaters such as those produced from animal oprations (swine) and from meat processing plants. The maximum power densities achieved in a single chamber microbial fuel cell were 261 mW/m2 for the swine wastewater and 108 mW/m2. These compare well with 146 mW/m2 recently reported for producing power in this system using domestic wastewater. Electricity production is accompanied by successful wastewater treatment as well. In the case of the meat packing wastewater 93% of the BOD and 87% of the COD was removed in the process of electricity generation.
