TRS provides in situ and ex situ heating solutions for the remediation of PFASimpacted soilsIn 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%.

PFAS

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.  

Projects

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. 

In Situ Thermal Treatment of PFAS in the Vadose Zone (ER20-5250)
This ESTCP project focuses on applying TRS’ patent-pending FlexHeater® thermal conduction heating services for PFAS removal from vadose zone soils. University laboratory results show that TRS’ patented PFAS remediation method achieves PFAS removal efficiencies of 99.998%. NAVFAC leads the project with Jacobs and TRS as co-performers. TRS anticipates a late 2021 or early 2022 implementation.

Ex Situ Thermal Treatment of PFAS (ER20-5198)
Using the same patented and patent-pending services as the in situ project mentioned above, this ESTCP project focuses on PFAS containing ex situ soil stockpiles at an air force base in Alaska. Paragon Professional Services, LLC leads the project with Brown University and TRS as co-performers. The team conducted its field demonstration and expects to have removal efficiency data within a few months.
