Abstract

It is possible to generate electricity from food processing and animal wastewaters using microbial fuel cells (MFC) to achieve both wastewater treatment and bioenergy production. A food processing wastewater was tested for electricity production in a two-chambered MFC. Preliminary tests demonstrated a maximum of 81 ± 7 mw/sq m (normalized to the anode surface area) using a high COD food processing wastewater (initial SCOD = 595 mg/L was diluted 10 times) with the treated wastewater reduced to a final COD of < 30 mg/L (95% COD removal). Using a one-chambered MFC and a pre-fermented wastewater, the maximum power was 371 ± 10 mw/sq m (150 ohm resistor). For the swine wastewater, the maximum power density was 261 mw/sq m (Voltage = 191 mv with 200 ohm resistor) with current density of 1.4 A/sq m. This is an abstract of a paper presented at the 230th ACS National Meeting (Washington, DC 8/28/2005-9/1/2005).
