TRS Group is a 100% employee-owned company with joint ventures in Brazil, China and Europe, is the leading provider of thermal remediation technologies for the in situ treatment of soils, groundwater and bedrock and the ex situ treatment of soil piles and dredged sediment. We excel at the quick cleaning of contaminated sites, often guaranteeing results, putting them back into productive reuse. Our focus is on reducing the costs of thermal remediation for the benefit of our clients, employees, shareholders and the general public. Our people are customer-focused and passionate about their work.

Why You Should 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 up contaminated soil and hauling it away can be prohibitively expensive and unsustainable. 

 Heating the subsurface essentially eliminates these issues. At TRS, we know how to apply thermal remediation technology 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, polycyclic aromatic hydrocarbons (PAHs), pesticides, energetic compounds and per- and polyfluoroalkyl substances (commonly known as PFAS). Our patented thermal remediation technology is certain, safe, sustainable and fast. In fact, we guarantee it.

We know how to apply heating technologies in complex environments. Steam Enhanced Extraction involves using boilers to generate steam, injecting the steam through wells.

How? 

Steam enhanced extraction (SEE) is an in situ thermal remediation technology used to heat higher permeability zones. Steam is generated at the surface in a boiler and injected through wells screened in the targeted permeable layers. We extract the migrating steam and hot liquids using multi‐phase extraction wells. TRS then treats the extracted water and vapor.

Which contaminants of concern (COCs)? 

Because SEE is an injection and delivery method, it can be very effective at displacing NAPLs within transmissive aquifers and pushing them to extraction wells. This reduces the mass of all the COCs in the NAPL. Typically, SEE removes less than 90% of the NAPL. After steam breaks through to extraction wells, we use flushing and pressure cycling to enhance the removal of the volatile components, with treatment efficiencies often exceeding 99%. 

SEE for large and deep sites 

We can place steam injection wells far apart at large and deep sites (more than 100 feet or 30 meters), dramatically reducing installation costs. For sites with permeable layers that are connected and of suitable geometry, SEE can be far less expensive than ERH or TCH.

SEE used to augment TCH or ERH at complex sites 

TCH and ERH excel at heating tight matrices. At sites that include permeable units with high groundwater flow velocities, which can rob energy from the treatment volume, we can combine technologies; that is, apply ERH or TCH to the tight materials and SEE to the permeable units. An example would be a silt or clay layer heated using ERH, and the underlying permeable aquifer heated using SEE.

How?         

Thermal conduction heating (TCH) uses heaters, typically powered by electricity, to distribute heat throughout the treatment zone. Through simple thermal conduction, heat propagates radially away

from heater wells, raising the temperature of the target volume. We space the heaters in a triangular pattern for optimal heat distribution. The heat fronts from each heater well will meet over the course of the remediation with thermal diffusivity limiting the rate of heat propagation. The tighter the heater spacing, the faster a site will heat up. Typically, we design our systems to reach boiling temperatures in two to four months.

We extract vapors from separate vacuum wells or from co-located extraction screens next to heaters. Principle of TCH – red columns are TCH heaters; blue are extraction wells.
