Why Consider Thermal Remediation

 

Remediating the subsurface environment can be a daunting challenge, as subsurface heterogeneity and groundwater flow dynamics make it extremely difficult to contact the contamination with remediation fluids. Further, simply digging it up and hauling it away can be prohibitively expensive.

 

Heating the subsurface essentially eliminates these issues, as we know how to apply heating technologies in very complex environments, including all types of soil and rock. We routinely reduce contaminant concentrations by more than 99% and guarantee results.

 

Target contaminants include chlorinated solvents, petroleum hydrocarbons, PAHs, pesticides, energetic compounds and PFAS.

 

Thermal remediation is certain, safe and fast. In fact, we guarantee it.

Thermal Technologies

FlexHeater® Thermal Conduction Heating

FlexHeater® TCH, applied in situ or ex situ for the treatment of VOCs and SVOCs, involves heating narrow diameter steel pipes to many hundreds of degrees Celsius. The heat propagates radially away from the pipes, evaporating the contaminants. Applying the flexible, patented heaters, TRS can achieve temperatures in the vadose zone and ex situ cells high enough to volatilize high boiling contaminants, including PAHs, PCBs, and PFAS. The technology is effective in all types of soil and bedrock, typically achieving 99% or more contaminant concentration reductions.

OptiFlux™ Electrical Resistance Heating

OptiFlux™ ERH, commonly used for in situ remediation of VOCs, applies electrical energy to the ground through electrodes. The soil matrix acts as a resistor and heats up to the boiling point of water. TRS is particularly adept at optimizing electrical flux, often completing projects ahead of schedule. We also can heat to sub-steaming temperatures, a process we call HEPA® remediation, to accelerate the natural degradation of contaminants. OptiFlux™ ERH is effective in all types of soil and sedimentary bedrock, typically achieving 99% or more contaminant concentration reductions.

Steam Enhanced Extraction

SEE involves using boilers to generate steam, injecting the steam through wells, and recovering the contaminants, water, and steam with multiphase extraction wells. As injection and extraction wells can be many tens of feet apart, SEE can be a low cost heating solution for NAPL-impacted, transmissive aquifers.

PFAS Technologies

PerfluorAd

PerfluorAd is a patented PFAS-impacted water treatment technology. We mix the aqueous phase PFAS with a flocculent, dropping out up to 99% of the anionic PFAS.

Thermal Treatment of PFAS-impacted Soils

Awarded a patent in June 2020 by the United States Patent and Trademark Office, TRS provides the only patented heating solution, in situ or ex situ, for PFAS remediation. TRS applies FlexHeater® TCH to generate soil temperatures between 300 and 400 degrees Celsius, volatilizing and capturing the PFAS vapors for subsequent surface treatment. Concentration reductions can easily exceed 99.9%.
