• Abstract: Long-term performance of a scaled-up air–cathode microbial fuel cell (MFC) and toxicity removal were studied with dairy wastewater (DW) used as the substrate. The MFC in a semi-continuous fow was strategically inoculated with consortium of Shewanella oneidensis and Clostridium butyricum. The scaled-up approach delivered a maximum power density of 0.48 W/ m3 (internal resistance of 73 Ω) removing 93% of total chemical oxygen demand and 95% of total biochemical oxygen demand at organic loading rate (OLR) of 0.9 kg COD/m3 /d and hydraulic retention time (HRT) of 21 days. It also achieved high removal efciency of nitrate (100%), organic nitrogen (57%), sulfate (90%) and organic phosphorus (90%). The power generation and DW degradation performance decreased with OLR of 1.8 kg COD/m3 /d and HRT of 10.5 days. Furthermore, testing of acute toxicity with the microcrustacean, Daphnia similis, revealed high toxic efect of the raw DW, but no toxic efects of the MFC efuent during 95 days of operation. These outcomes demonstrated that scaled-up MFC fed with high strength DW should be an efective system for pollutants removal and simultaneously energy recovery.
