What is thermal remediation?
What is thermal remediation?
Thermal remediation is the technology that makes use of steam injection and possibly electrical resistance heating. In situ thermal remediation is the injection of energy into the subsurface to mobilize and recover volatile and semi-volatile organic contaminants.
What is in situ thermal treatment?
What is In Situ Thermal Treatment? In situ thermal treatment methods move or “mobilize” harmful chemicals in soil and groundwater using heat. The chemicals move through soil and groundwater toward wells where they are collected and piped to the ground surface to be treated using other cleanup methods.
How much does thermal remediation cost?
Thermal remediation will run anywhere from $2,000 to $6,000, while chemical processes can run anywhere from $1,300 to $5,000.
What is thermal remediation for bed bugs?
Thermal Remediation® utilizes a high powered heater to raise the ambient air temperature within a space to a bed bug lethal zone, killing all life stages from adults to eggs in their tracks. Thermal Remediation involves treating units with portable electric heaters to increase the ambient temperature to 120-135°F.
How long does thermal remediation take?
More traditional cleanup techniques can take between five and seven years to complete but using an innovative thermal remediation technology to heat the soil and groundwater beneath the former dry cleaner, levels of contamination in the treatment area were effectively eliminated in just 120 days.
How fast does thermal radiation travel?
As radiation uses electromagnetic waves to transfer heat, it’s speed will also be the same as the speed of light. Thus, the speed of heat radiation is 3×108m/s and it does not need any medium to travel. Heat radiation travels along a straight line.
What is thermal desorption analysis?
Analytical thermal desorption, known within the analytical chemistry community simply as “thermal desorption” (TD), is a technique that concentrates volatile organic compounds (VOCs) in gas streams prior to injection into a gas chromatograph (GC).
What does ex situ mean in thermal treatment?
Ex situ thermal treatment generally involves the destruction or removal of contaminants through exposure to high temperature in treatment cells, combustion chambers, or other means used to contain the contaminated media during the remediation process. Thermal processes use heat to separate, destroy, or immobilize contaminants.
Which is the most expensive ex situ process?
Ex situ processes, however, require excavation of soils leading to increased costs and engineering for equipment, possible permitting, and materials handling worker safety issues. Thermal treatments offer quick cleanup times but are typically the most costly treatment group.
How does an ex situ desorption system work?
Overview. EX SITU THERMAL DESORPTION involves the application of heat to excavated wastes to volatilize organic contaminants and water. Typically, a carrier gas or vacuum system transports the volatilized water and organics to a treatment system, such as a thermal oxidation or recovery unit. Based on the operating temperature of the desorber,…
Which is more expensive in situ or thermal treatment?
Thermal treatments offer quick cleanup times but are typically the most costly treatment group. This difference, however, is less in ex situ applications than in in situ applications. Cost is driven by energy and equipment costs and is both capital and O&M-intensive.
