Per- and polyfluoroalkyl substances (PFAS) are a family of more than 5,000 compounds that can persist in the environment for centuries. Further, they are quite soluble and have low vapor pressures, which means they do not volatilize readily. Cornelsen, a TRS Europe partner, has developed PerfluorAd, a patented PFAS-impacted water treatment technology that involves mixing the aqueous phase PFAS with a flocculent, dropping out up to 99% of the anionic PFAS. Simple filtration methods, such as sand packs, filter the precipitated floe for subsequent treatment.

The PerfluorAd system is ideal for cleaning out fire-fighting systems, such as trucks, storage vessels, hoses and piping, impacted by aqueous film forming foam (AFFF) that contains per- and polyfluoroalkyl substances (PFAS).

Applying our FlexHeater thermal conduction heating technology, we can generate temperatures to volatilize per-and polyfluoroalkyl substances (PFAS) in situ from the vadose zone or ex situ from a TRS-designed treatment cell. PFAS impacts are prevalent in the vadose zone, as the deposition of these compounds resulted largely from the use of aqueous film forming foams.
