“…Electrons released from the substrate in the anode compartment and transferred to the cathode are taken up by the azo dye in the cathode compartment, thereby reducing the dye. The cathodic reduction potential of MFCs was evaluated by the removal efficiency of the azo dye at the cathode 20 . The wavelength scan results of the raw azo dye and reduced azo dyes in the cathode chamber at the end of each experiment are shown in Fig.…”

“…Preparation of the anaerobic inoculum used in the experiments was carried out as stated in the previous study of the authors. 20 A double chamber H-type MFC with a volume of 500 mL for each chamber was used in the experiments. Raw, diluted or pre-treated SEP and exoelectrogen-rich inoculum were added at a ratio of 1.1 (v/v) in the anode chamber to provide an average mixed liquor suspended solids (MLVSS) of 1500 mg L −1 .…”

BACKGROUNDThe high organic load and low biodegradability of the effluent from baker's yeast production limit its use as a substrate in microbial fuel cell (MFC) systems. In this study, baker's yeast production wastewater was used as a substrate in the anode chamber to assess the impact of various pretreatment methods [dilution, microwave (MW), acidic‐thermal, basic‐thermal and ultrasound (US)] on electricity generation and waste treatment. Additionally, azo dye was used as an electron acceptor at the cathode. Power density and coulomb efficiency were evaluated for electricity generation, and chemical oxygen demand (COD) removal and azo dye removal parameters were evaluated for treatability.RESULTSThe maximum power densities obtained were 83.53, 46.54, 19.41, 67.40, 41 and 33 mW m−2 for MW, acidic thermal, alkaline‐thermal and US pretreatments, diluted raw and raw wastewater, respectively. To determine the most suitable pretreatment method, PROMETHEE was performed using the criteria of maximum power density, COD removal, azo dye removal, coulombic efficiency and pretreatment cost. The most suitable method was found to be MW pretreatment. The order of the alternatives was found to be MW > US > acidic/thermal > diluted raw > raw > alkaline/thermal. With the MW pretreatment, 81.34% azo dye removal, 5 g L−1 COD removal, 0.27% coulombic efficiency and €0.284 L−1 pretreatment cost were obtained.CONCLUSIONThe most suitable pretreatment method to be applied to wastewater for the treatment of baker's yeast production wastewater and high energy production was determined as MW using the PROMETHEE approach. © 2023 The Authors.
