TRS provides in situ and ex situ heating solutions for the remediation of PFAS–impacted soils. In fact, the U.S. Patent and Trademark Office awarded TRS a patent for our PFAS thermal remediation solutions. Further, our patent-pending FlexHeater® thermal conduction heating (TCH) services can reduce PFAS concentrations by more than 99.99%.
Our patented process involves heating the impacted soils, in situ or ex situ, to temperatures between 300 and 400°C and maintaining the elevated temperatures for up to two weeks. The process is safe and remarkably effective.
In 2020, the Department of Defense, through its Environmental Security Technology Certification Program (ESTCP), awarded TRS and collaborators two projects, each focused on the thermal treatment of PFAS-impacted soil: in situ thermal treatment in the vadose zone and ex situ treatment of soil piles.
