Electrodialysis remediation can detoxify fly ash by separating metals from fly ash through dissolution, acidification, and membrane separation (Meer and Nazir, 2017). Kirkelund et al. (2015) remedied MSWI-FA using electrodialysis, which led to a notable decrease in the leaching concentration of various heavy metals, including Cd, Cu, Pb, and Zn.
