Recent studies performed by our partner Krüger has shown that our patented TCH technology can be an effective treatment for poly- and perfluoroalkyl substances (PFAS). The need for remediation of PFAS is growing substantially because of increased regulatory attention to this emerging contaminant.
Laboratory studies conducted by Krüger have shown that our TCH technology delivers better than 99.99% removal of PFAS contaminants from soil. Soil samples from an aqueous film-forming foam (AFFF) handling facility, containing initial PFAS concentrations close to 200 mg/kg, were tested in a laboratory-scale treatability study. The soil was heated to temperatures from 250°C to 500°C and soil samples, as well as vapor and condensate samples, were collected for analysis during and after the study. The studies were designed to simulate the removal of PFAS during TCH full-scale treatment either in situ or ex situ using TerraTherm’s in pile thermal desorption (IPTD®) system.
