Design of a synergistic combined electrodialysis/anodic oxidation system for simultaneous AMX membrane fouling mitigation and enhanced dye degradation

•Design of highly stable Pb/PbO2 anode by acidic electrolysis for anodic oxidation.•Comparison of ED and combined ED–AO for anionic dye oxidation and mineralization.•Combined ED–AO showed superior dye oxidation performance compared to single ED.•Unlike in conventional ED, membrane fouling was not pronounced in combined ED–AO.•Oxidation performance and membrane fouling were studied under different conditions.
