To move beyond just sequestering per and polyfluoroalkyl substances (PFAS) many groups are looking to find methods to completely break down the carbon fluorine bond and achieve mineralization of PFAS compounds. ECT2 has developed technologies that concentrate PFAS to help make these technologies feasible. Due to this involvement in many different destructive technology pilots, this will be a unique overview on many of the destruction options that are promising. This presentation will give an overview of what some of these technologies are, how they work, and their technology maturity. The following technologies will be highlighted: Plasma, Thermal, Electrochemical Oxidation, Electron Beam, Advanced Oxidation, Supercritical Water Oxidation, Hydrothermal Alkaline Treatment, Sonolysis, UV-sulfite, Zero-Valent Iron, Alkali Metal Reduction, and Biodegradation. Data and time will be focused on two promising technologies; Plasma and Electrochemical Oxidation.
Recent piloting efforts with both Plasma and Electro Oxidation values and discussions will be reviewed in this presentation specifically. Data for mineralization of both long and short chain compounds will be reviewed. This will build upon technologies that remove and concentrate PFAS and dive directly into complete removal of these forever chemicals from our society and align with the EPA PFAS Blueprint goals to completely remove these compounds.
