Potter, P., B. Crone, AND M. Mills. Pilot-scale thermal treatment of PFAS-laden materials. ACS Spring 2024 National Meeting, New Orleans, LA, March 17 - 20, 2024.
Impact/Purpose:
There is a critical need for research involving thermal treatment of PFAS. This presentation will involve data that furthers our understanding of the fate of PFAS in both biosolids incineration and GAC reactivation.
Description:
Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that have been in use since the 1940s in a wide array of consumer products. PFAS are persistent in the environment and bioaccumulate. Thermal treatment methods are currently applied to a variety of materials, including sewage sludge and granular activated carbon (GAC). There is a critical need to assess the efficacy of existing and emerging thermal treatment methods to completely destroy or mineralize PFAS. Both biosolid incineration and GAC regeneration are currently utilized to treat materials that contain PFAS, but these treatment are not necessarily optimized for PFAS destruction. Results from a pilot-scale system used to perform both biosolid incineration and GAC regeneration will be presented along with a summary of current EPA research in this field.
