Objective• To demonstrate electricity could be generate from wastewater.• To examine efficiency of wastewater degradation when using MFCs.
Methodology MFCs configurations and running• Flat plate microbial fuel cell• Ethanol wastewater >> source inoculums and substrate• Phosphate buffer solution >> Basal medium
Analyze• Voltage output and power generation• Chemical oxygen demand (COD) removal of the wastewater
Result from previous research Substrate Source Type of MFCs Current density inoculums (mA/cm²)Corn stove Domestic Single chamber/ 0.15biomass wastewater carbon paper anode /carbon cloth cathodeEthanol Anaerobic Double chamber 0.025 sludge from aqueous cathode wastewater /carbon paper plant electrodesStarch Starch Single chamber 0.09processing processing /carbon paper anode /wastewater wastewater air cathode
Discussion• The factor that affect the MFCs performance are substrate , source inoculums, type of MFC ,operation condition and other.• Application of MFCs are limited because of their low power density .
Conclusion• Electricity will be generating from MFCs using ethanol wastewater as substrate. So , this study will be leading improve the performance of MFCs for practical application.
