PER- AND POLYFLUOROALKYL SUBSTANCES REMEDIATION
Last updated:
Abstract:
The present invention relates to reduction of per- and polyfluoroalkyl compounds (PFAS) in a desired zone of treatment for the continuous remediation of contaminated solids and liquids. In particular, embodiments of the present invention relate to the in-situ treatment of solids and liquids by a particular combination of reagent and conditions. The reagents include an oxidant and a metal catalyst. Disclosed method combines low temperature thermal remediation with chemical oxidation to destroy poly- and perfluoroalkyl substances in-situ. The disclosed methods may enhance destruction of organic contaminants in the desired zone of treatment. The present invention also relates to a method for applying the remediation compositions to contaminated sites and controlling the process by monitoring the degradation event to achieve maximum reduction of PFAS.
