Thermal Rediation for Treatment of PFAS Source Areas

Per- and polyfluorinated substances (PFAS) are known as forever chemicals because they are persistent in the environment and difficult to remove. Tackling these contaminants is feasible with the right technology. Thermal conductive heating (TCH) is an effective remediation solution for PFAS and other recalcitrant compounds. Recent laboratory studies conducted by TerraTherm partner Krüger have shown better than 99.99% removal of PFAS contaminants when simulating the TCH efficiency.

You know there’s more to project success than technology alone. Experience matters. TerraTherm’s Technology Director with guest speaker Søren Eriksen, Chemical Engineer from Krüger. They addresses the literature background as it relates to thermal removal of PFAS, describes the conducted lab testing and results. They also touch on the fate of the thermally treated PFAS compounds in the process, and presents how a field application will be implemented.

Thermal Treatment of PFAS – Does it Work?

Many promising Pump & Treat Technologies are promoted to treat PFAS in groundwater which is excellent to reduce the risk of further spreading. However, no technologies have been applied to eliminate PFAS source zones so far.

Join three experts from TerraTherm and our European partner KrugerVeolia when they address the topical issue: Is it possible to remove the source totally and permanently?

You will learn:

  • How do you analyze PFAS – a family with 3000+ members
  • What are the lowest and the most optimal temperatures for removing PFAS
  • What is the fate of the fluorine
  • Which lab tests and full scale projects have been performed worldwide
  • What to look for and what to avoid in terms of successful remedy of PFAS source zones

The Fate of PFAS During Thermal Remediation

Is it possible to remediate PFAS contaminants? Our research and experience indicate that it is indeed possible using high-temperature thermal remediation, although there are important factors to consider  to ensure complete removal and treatment of not only target PFAS but also non-target PFAS such as precursors. In this webinar, we dive into the science of using thermal remediation to treat soil contaminated with PFAS and explore the use of our proven high-temperature thermal remediation technology, where soil temperatures ranging from 350 to 500 degrees Celsius are maintained to achieve stringent cleanup levels. Through our research, which we will share during the webinar, we were able to close the fluorine mass balance and determine the fate of the PFAS compounds during thermal treatment.  This allowed us to assess the effectiveness of high-temperature thermal remediation on the removal of PFAS from soil and to design appropriate off-gas treatment systems to ensure that the potential to emit both target and non-target PFAS, including fluorinated hydrocarbons like CF4 and other significant greenhouse gasses, are appropriately managed.
