Microbial Fuel Cell (MFC) for energy generation and wastewater treatment

摘要: Aims: Microbial fuel cells (MFCs) are promising method for electricity generation with simultaneous treatment of organic compounds in wastewater by using bacteria.Scope: In a pilot study, Synthetic wastewater based on glucose was used as carbon resource for microorganisms and ruminant rumen bacteria were used for microbial consortium. Microbial fuel cells with two compartments were operated in continuous mode at 720 hrs and temperature 20±4 º C. Organic loading rate and hydraulic retention time were effective factors in power density and voltage generation.Conclusion: By increasing the organic loading rate and decreasing retention time, power density increase too. Maximum voltage and power generation in operating period were 700mV and 1700mW/m2, respectively. Moreover, volumetric power reached 12 W/m3 and peak power produced at 10kΩ resistance.
