An Electrocoagulation and Electrooxidation Treatment Train to Degrade Perfluoroalkyl Substances and Other Persistent Organic Contaminants in Groundwater

Abstract

This study aims at developing a novel treatment train that combines electrocoagulation (EC) with electrochemical oxidation (EO) treatment to remove and degrade per- and polyfluoroalkyl substances (PFAS) including perfluoroalkyl acids (PFAAs) and their organic co-contaminants in contaminated groundwater. PFAS are extremely persistent because of their unique molecular structures, and currently, there is no cost-effective technology that is applicable for on-site PFAA destruction. This study is of great societal and environmental significance by providing a technology potentially practical for eliminating and destructing PFAS in groundwater. Although PFAS are evaluated as the target contaminants in this study, the EC and EO technologies can be used individually or in combination to address a wide range of different co-contaminants.
