Research and Development of a Sediment Microbial Fuel Cell Module for a Livestock Wastewater Treatment System

Short Introductive summary

The purpose of this research is to recover extra micro-electricity and biogas from the anaerobic digestion of livestock wastewater simultaneously. Our team initially applied basic two-chamber microbial fuel cell (MFC) reactors using piggery wastewater as fuel to characterize the patterns of micro-electricity from sediment microbial populations. Analytic results of the Fast Fourier Transform (FFT) show that the current of this MFC includes a direct current (DC) and alternating current (AC), which may be related to the behavior of the microbes studied in ours. Besides, pilot-scale (180-L polyethylene tanks) experiments were performed using a self-designed and self-assembled sediment MFC module (SMFC) with cattle wastewater as fuel in a cattle farm. All micro-electricity produced from the SMFCs was stored in 10 capacitors with inductors. For practical applications, integrating 10 serial/parallel capacitors and a DC-to-DC booster can charge a rechargeable battery for at least 2.5 min. Hopefully, the SMFC can be applied to support the electricity needed for DC aerators in the automatic piggery wastewater treatment soon.
