ERH vs. TCH: How to Choose Your Thermal Remediation Technology (and Why)?

“How do I choose between ERH and TCH?”

It’s one of the most commonly asked questions when considering thermal remediation, and in this webinar one of the industry’s leading experts will answer it. Join TerraTherm, a Cascade Company’s Vice President John LaChance as he introduces the basic operational theory and concepts for both technologies. He’ll discuss their application to a set of typical site conditions (e.g., low and high permeability zones in unconsolidated and bedrock formations) and contaminants (e.g., CVOCs), and highlight typical design approaches, assumptions, and the pros and cons of each.

John will share real-life examples of full-scale projects involving electric resistance heating (ERH) and thermal conductive heating (TCH), including detailed breakdowns and comparisons of costs. He’ll also touch on ETDSPTM, a form of ERH that employs active injection and extraction of water. If you have burning questions about how ERH and TCH stack up, this is your chance to get them answered.

Heat It Up: How High Temp Thermal Tackles Recalcitrant Chemicals

What do coal tar, PAHs, PCBs, pesticides, dioxins, PFAS and mercury all have in common?

They’re all recalcitrant chemicals that are hard to treat using traditional remediation methods. Sites with these contaminants are nearly unaffected even by thermal treatments reaching the boiling point of water. Luckily, high temperature thermal conductive heating (TCH) can reach temperatures of more than 300°C, high enough to address these difficult chemicals.

In this webinar, TerraTherm’s Steffen Griepke will discuss where high temperature thermal is applicable, what chemicals can be targeted and what results can be achieved. Different implementation approaches tailored to the site specific circumstances will be presented, and both in situ and ex situ case study examples will be provided. Steffen will draw on TerraTherm’s 25 years of experience working with high temp thermal projects to answer participant questions during the Q&A.

If you have interest in cleaning up some the most difficult chemicals out there, this is a webinar you don’t want to miss.

What You Need To Know About Thermal Remediation For MGP Sites

When a manufactured gas plant (MGP) site is identified for treatment, the typical remediation approach can be expensive and involve hazards for crews and the community. Any time you excavate contaminated soil and transport it for treatment or disposal, you are introducing potential safety and liability issues.

Luckily, in situ thermal remediation (ISTR) is often a safe and cost-competitive alternative.

In this webinar, Vice President of Thermal Technology John LaChance will briefly introduce the primary ISTR technologies, their applicability, and their primary removal mechanisms at MGP sites. He will discuss the key design considerations for varying conditions and remedial goals, and present a real-life example of an MGP site that was recently remediated with ISTR – including analysis and discussion of the potential role in situ smoldering may play at some sites in the removal of creosote/coal tar. John will also cover projects where the goal was not complete removal but volatilization of the low boiling point compounds and in situ immobilization of the high boiling point compounds, such as heavier range TPH and PAHs.

ISTR Challenges Part 1: Thermal Conductive Heating

In Situ Thermal Remediation (ISTR) is a widely used approach for treating highly contaminated source zones (e.g., DNAPL and LNAPL) at hazardous waste sites because of its reliability and effectiveness at removing a wide range of chemicals from a variety of geologic settings.  As experienced consultants know, large scale remediation projects come with unique challenges.

Vice President of Development, John LaChance, and Senior Technologist, Erin Hauber, are here to share some of the lessons learned from implementing thermal conductive heating (TCH) at more than 80 sites including:

  • unexpected COCs and increased mass
  • higher groundwater flux than expected
  • materials selection for sites with highly corrosive COCs
  • how to handle highly flammable COCs in the vapor treatment system
  • mitigating vapor intrusion issues that may arise during treatment

Join the discussion for insight to help avoid costly project delays in your next thermal project.  There will be time for questions at the end, so bring the thermal remediation questions you’ve never had a chance to ask.

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.
