NASF/AESF Foundation Research Project #120: Electrochemical Destruction of Perfluorooctanesulfonate in Electroplating Wastewaters: Full Progress Report
This NASF-AESF Foundation research project has been ongoing since April 2019 but was unavoidably interrupted by the SARS CoV-2 pandemic of 2020-21. This report (1) re-introduces the project and (2) covers all of the work thru June 2021. The project focuses on an electrochemical, destructive treatment strategy for the remediation of relevant PFASs in electroplating wastewater. The overall objective is to utilize a cost-effective reactive electrochemical membrane (REM) for the removal of PFAS from synthetic electroplating wastewater.
