Ex Situ (IPTD & HB1100)
WHAT IS IN PILE THERMAL DESORPTION®(IPTD®)?
TerraTherm, a Cascade Company’s IPTD process uses thermal conduction heating (TCH) to provide within-the-soil remediation that can be designed to treat any organic contaminant, streamlines material handling, and eliminates the need for off-site disposal of contaminated soils and sediment.
Treatment cells composed of insulated, covered soil piles are equipped with electrically-powered heating elements. The heating elements operate at uniform temperatures of 700-800°C along their entire length. TCH ensures that all areas within a treatment cell achieve the target temperature within the specified time-frame (a typical heating period is 40 days per batch).
Benefits of IPTD
- TerraTherm designes the process to be operated cost-effectively at full-scale within the available site footprint and time-frame.
- IPTD treatment cells are designed to be inexpensively emptied and refilled for quick batch change-out and efficient utilization of off-gas treatment equipment.
- Efficiently sequenced, IPTD can be one of the least expensive thermal remediation technologies, considerably less expensive in many cases than conventional ex situ thermal desorption.
WHAT IS THE HEATED-BOX (HB)1100?
TerraTherm’s patented HB1100, is a configuration of the above mentioned IPTD technology. It is an ex situ, on-site, batch-fed, indirect thermal desorption technology for remediation of soil, sediments, and construction debris. Each unit has a soil capacity of 100 cubic yards.
- Scalable - Multiple units can be deployed for larger treatment volumes and expedited schedules.
- Centralized treatment equipment - Provides efficient utilization of equipment and labor by treating batches in a sequential, staggered-operation fashion.
- Mobile/Modular - Plug & play equipment components.
- Streamlined - Eliminates pretreatment material
SUITABILITY of IPTD and HB1100
- Land disposal restricted RCRA listed hazardous wastes, including hydrocarbon D, F & K listed wastes.
- Wastes associated with drill cuttings (IDW) and manufacturing processes.
- Facility decontamination: concrete and non-combustible building materials.
- Any soil types including saturated and unsaturated sands and clays.
- Any Total Petroleum Hydrocarbons (TPHs), chlorinated solvents, and semi volatile organic compounds, including MGP coal tar or PCBs.
- Dioxins and furans.
