IN PILE THERMAL DESORPTION IPTD

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.

HB1100 BENEFITS

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
