Scope: Thermal Oxidation of Off-gas | Lab | Treatment Media: Aquarden: PFOS-based AFFF material: 3M Lightwater produced prior to 2002. Lightwater produced before 2002 contains both short-chain and long-chain PFAS, including the C8 compounds perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA)
Treatment Temperature (°C): 590
Treatent Time: 60
Time Units: Second
Treatment Details: Pressure (MPa): 24; Oxidizer: Air; Alkaline treatment type: KOH; Alkaline treatment location: Influent
