DEMONSTRATION OF SMOLDERING COMBUSTION TREATMENT OF PFAS-IMPACTED INVESTIGATION-DERIVED WASTE
Major, D.W.
SERDP Project ER18-1593, 40 pp, 2019
A surrogate fuel was evaluated to support a smoldering process that achieves temperatures (> 900°C) sufficient to destroy per- and polyfluoroalkyl substances (PFASs). The bench-scale study was conducted in two phases. Phase I evaluated if granular activated carbon and ground rubber could smolder at required temperatures when mixed with sand. Phase II examined the extent and repeatability of remediation of the solid matrix by smoldering combustion (SC) by measuring (1) PFAS concentration in soil before and PFAS concentration in soil/ash after treatment; (2) PFAS in emissions; (3) and hydrofluoric acid concentrations as a measure of total PFAS mineralization. All testing was performed in reactors specifically designed for testing SC. https://www.serdp-estcp.org/Program-Areas/Environmental-Restoration/ER18-1593
