Application of microbial fuel cell technology for vinasse treatment and bioelectricity generation
Our study evaluated the performance of different two-chambered microbial fuel cell (MFC) prototypes, operated with variable distance between electrodes and Nafion membrane and specific inoculum concentration, applied for vinasse treatment.
The performance of the developed MFC resulted in a maximum current density of 1200 mA m−2 and power density of 800 mW m−2 in a period of 61 days. MFC performed a chemical oxygen demand removal at a rate ranging from 51 to 60%.
Taking our preliminary results into consideration, we concluded that the MFC technology presents itself as highly promising for the treatment of vinasse.
