Electrochemical Oxidation for Treatment of PFAS in Contaminated Water and Fractionated Foam─A Pilot-Scale Study

ACS ES&T Water, Journal Year: 2023, Volume and Issue: 3(4), P. 1201 - 1211

Published: March 15, 2023

Per- and polyfluoroalkyl substances (PFAS) are persistent synthetic contaminants that present globally in water exceptionally difficult to remove during conventional treatment processes. Here, we demonstrate a practical train combines foam fractionation concentrate PFAS from groundwater landfill leachate, followed by an electrochemical oxidation (EO) step degrade the PFAS. The study combined up-scaled experimental approach with thorough characterization strategies, including target analysis, sum parameters, toxicity testing. Additionally, EO kinetics were successfully reproduced newly developed coupled numerical model. mean total degradation over designed reached 50%, long- short-chain degrading up 86 31%, respectively. resulted decrease toxic potency of water, as assessed transthyretin binding bacterial bioluminescence bioassays. Moreover, extractable organofluorine concentration decreased 44%. Together, these findings provide improved understanding promising for on-site remediation PFAS-contaminated water.

PFAS pollution threatens ecosystems worldwide

Science, Journal Year: 2023, Volume and Issue: 379(6635), P. 887 - 888

Published: March 2, 2023

Toxic perfluoroalkyl and polyfluoroalkyl substances (PFASs) have been widely used for decades in textiles, food wrappings, flame retardants, water proofing, offshore industry, cosmetics are now ubiquitous the environment (1). PFAS compounds extremely resistant to biodegradation persist millennia, which complicates their management cleanup (2). Their toxic properties make them carcinogenic, endocrine disruptive, immunotoxic (3). In February, response PFASs’ threat ecosystems, biodiversity, security, drinking (4, 5), five EU countries proposed a complete phaseout of PFASs (6). Other should ban use as well.
