| Project : | Low Temperature Thermal Desorption of TPH contaminated soil the Fort Lewis site at a fixed facility in Tacoma (WA). |
| Duration : | 10 projects over the last 8 years |
| Budget : | > 1,000,000 USD (Prime & Sub-contractors) |
Soil Treatment & Clean-Up Objectives :
The soil to be treated contained TPH concentrations up to 15,000 ppm. All soils were cleaned down to a-less than 50 ppm TPH. Air emissions were in accordance with the local air permit conditions (air permit is available on www.deep-green.com in the permit section).
Equipement:
Contaminated soils were processed by a counter flow, direct fired LTDU (Low Temperature Desorption Unit) with nominal capacity of 35 tons (US) per hour. The equipment train included a pre-screener, belt scale conveyor, rotary dryer, fabric filter baghouse, thermal oxidizer, soil moisturizer, and radial stacker. Natural Gas and recycled oil were used as process fuel.
