This three-year Project Grant from the National Science Foundation's Division of Chemical, Bioengineering, Environmental, and Transport Systems will support $249,710 in research at the University of Nevada, Reno to investigate thermal regeneration of granular activated carbon (GAC) laden with per- and polyfluoroalkyl substances (PFAS). PFAS are difficult to degrade and have emerged as priority pollutants found in drinking water. GAC sorption is the most efficient method for removing PFAS from drinking water sources but spent PFAS-laden GAC needs to be disposed of or regenerated for reuse. This research aims to advance the fundamental understanding of PFAS degradation, transformation and destruction pathways during thermal regeneration of PFAS-laden GAC to enable sustainable reuse of this sorption material. Outcomes will further the NSF Engineering program's goal of improving water treatment through innovative research.
