GTR™ is a system that is also used for onsite soil treatment, when the soil is treated on site after excavation (no transportation off site).

 

The Process

The contaminated soils are excavated and stored in a pile; while building the pile, heating and extraction wells are layered into the soil. On the first layer of contaminated soil, a range of wells is placed. Then again a layer of soil, a range of wells, etc. In a standard design, piles are 65 feet long and between 9 and 21 feet high. The volume of the soil to be treated determines the final width.

 

In case of large volumes, the number of soil treatment units will be multiplied, and are set up week after week. With such an overlapping setup, large treatment capacities can be achieved with reasonable costs.
