Webinars

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.

On sites with contaminant masses counted in the hundred-thousand to million pound range, it’s imperative you choose the right technology for your remedy.

Thermal Technologies are widely used to target high mass contaminated sites where non-aqueous phase liquids (NAPLs) are known to be present. While the geology and hydrogeology of a site typically is a driving factor for technology selection, the mass distribution, chemical composition and thermal behavior for the site contaminants are often the key drivers in determining in which phase the mass is mobilized, and thus the extraction strategy. For VOCs, mobilization in the vapor phase typically fully governs the mass removal. However, for more complex mixtures of high boiling point hydrocarbons, that may not be the case.

In this webinar, Technology Director Steffen Griepke explains what to consider when selecting and designing your thermal remedy for optimized mass removal. He shares best practices and examples drawn from the two decades he worked in thermal remediation.

An in situ thermal remediation (ISTR) design may look good on paper, but how will it perform in the field?

Thermal Conduction Heating (TCH), Electrical Resistance Heating (ERH) and Steam Enhanced Extraction (SEE) are widely used thermal technologies capable of effectively remediating a variety of chemicals in various varying subsurface settings, yet sometimes operations do not perform as planned. Due to the aggressive nature of thermal remediation in parallel with pro-active monitoring, operational challenges must be addressed immediately, typically within days rather than weeks. Lessons learned from more than 100 full-scale TCH, ERH and SEE projects will be discussed, focusing on common operational challenges that arise during full-scale thermal projects.
