The presence of Per- and Poly fluoroalkyl substances (PFAS) in landfill leachate has become a significant challenge. In this study, Aclarity's electrochemical oxidation (EOx) system was tested at different power settings to determine the conditions at which PFAS and ammonia are simultaneously degraded at satisfactory rates in synthetic wastewater and landfill leachate. PFAS and ammonia test results revealed that both degrade more quickly in this system as applied power to the system increases. However, for solutions with lower background organics, a low power with a lower pH proved to be just as effective in the degradation of the MA6 PFAS. Further landfill leachate tests with known composition should be conducted to better understand the effects of precursors and other organics on the electrochemical oxidation of PFAS and ammonia. Optimizing flow within the reactor is an additional way to boost PFAS degradation.
