On-Site Destruction of AFFF and PFAS-Contaminated Wet Waste

On-site disposal of per- and polyfluoroalkyl substance (PFAS) contaminated wet wastes and brines remains a pressing need within the environmental remediation industry for both Defense and non-Defense customers. Aquagga is developing a continuous, field-deployable hydrothermal reactor that leverages the unique properties of high-temperature, high-pressure (HTHP) water, amended with cheap and commercially available reagents, to completely mineralize PFAS compounds to concentrations below EPA health advisory levels. Hydrothermal processing is “PFAS agnostic,” in that all PFASs are mineralized under the reaction conditions, and the contained reaction environment prevents the off-gassing of volatile fluorocarbons. For these reasons, hydrothermal processing is the best candidate technology for the safe disposal of aqueous film forming foam (AFFF) stockpiles and high-concentration filtration byproducts.
