Innovative hybrid approach for enhanced PFAS degradation and removal: Integrating membrane distillation, cathodic electro-Fenton, and anodic oxidation

Journal of Environmental Management, Journal Year: 2025, Volume and Issue: 379, P. 124818 - 124818

Per- and polyfluoroalkyl substances (PFAS) are persistent environmental contaminants that pose significant toxicity risks to humans ecosystems. Traditional advanced oxidation processes using boron-doped diamond (BDD) anodes degrade PFAS in wastewater effectively but suffer from slow kinetics high energy costs, limiting commercial application. This study introduces a hybrid process combining cathodic electro-Fenton (EF), anodic via BDD anode, membrane distillation (MD) improve perfluorooctanoate (PFOA) degradation efficiency reduce use. Increasing the current density 50 500 A/m2 significantly raised concentration of produced H2O2 0.25 mM 2.3 mM, accelerating PFOA mineralization. At A/m2, no mineralization occurred EF/BDD process, while EF/BDD-MD achieved 45% due increased electrolytic cell. 95% Findings reveal EF-generated •OH radicals assist degradation, BDD(•OH) anode was primary driver, driving 80% reaction. initiated by direct electron transfer at surface, followed homogeneous heterogeneous enhancing process. The also lowered consumption, making treatment feasible for large scales.
