  • In-Pile thermal desorption for treatment of Dioxin-Contaminated soil in Japan

    Abstract A demonstration of thermal treatment of dioxin-contaminated soil was completed in Japan, under the sponsorship of the Japan Ministry of the Environment. TerraTherm’s proprietary In-Pile Thermal Desorption process was demonstrated to successfully treat the soil to the required standard of 1,000 picograms of 2,3,7,8-tetrachlorodibenzodioxin (TCDD) toxic equivalents (TEQ) per ...

  • Contaminant removal from dry and wet sands by thermal desorption

    Infrared heating was used to determine the effects of temperature and moisture on the removal of selected organic compounds from contaminated sand matrices. Quartz sand was used as a chemically inert surrogate for soil to isolate the heat transfer and mass transfer effects without any chemical contribution from soil. The selected organic contaminants were 3-nitrobenzene sulphonic acid, sodium ...

  • Thermal Desorption Unit - Overview, Types and Applications

    Thermal desorption is basically a remediation technique heavily used to clean contaminated soils, sludge’s etc. This technique uses heat to vaporize the contaminants, and works only for volatile contaminants. These include typically organic wastes composed of hydrocarbons, such as coal tar wastes, chlorinated solvents, oil refining wastes, fuels, pesticides, and a lot other. In the process, ...

  • On-Site Thermal Desorption of PCP- and Dioxin-Contaminated Soil at the Coleman-Evans Wood Preserving Site, Whitehouse, Florida, USA

    ABSTRACT Roy F. Weston, Inc. (WESTON®) has designed an indirect thermal desorption process (known as the LT3-HT) to treat solids and sludges contaminated with hazardous and toxic materials. The LT3-HT is a high-temperature, high-capacity thermal desorption system designed for treatment of semivolatile and volatile organic contaminants that require high treatment temperatures. The LT3-HT ...

  • Soil baked to clean up contamination...

    Can an old drill site be cleaned up without adding truckloads of contaminated soil to the landfill? Chevron Canada will be using a technology called thermal desorption to clean up a site located 13 kilometres southwest of Pincher Creek. Leif Sollid, spokesman for Chevron, who is the operator of the site, said they considered two options for the clean up. The soil is classified as a non-dangerous ...

  • Ex Situ Thermal Treatment for Soil, Sediment, and Sludge

    The main advantage of ex situ treatments is that they generally require shorter time periods, and there is more certainty about the uniformity of treatment because of the ability to screen, homogenize, and continuously mix the soils. Ex situ processes, however, require excavation of soils leading to increased costs and engineering for equipment, possible permitting, and materials handling worker ...

  • Treatment of Oil-Contaminated Soils for Identification and Classification

    An experimental investigation was performed to evaluate the effects of oil contamination on soils and to establish a methodology to identify and classify contaminated soils. Identification and classification tests were performed before treatment, cleaning, stabilization, or disposal of contaminated soils.There are no standards for identification and classification of contaminated soils. ...

  • One of Europe’s most contaminated sites

    VSD Avenue, a joint venture partnership between VolkerStevin, DEC and Sita Remediation, started work at the beginning of September on the remediation of the former Avenue Coking Works in Chesterfield; one of the most heavily contaminated sites in Europe. Guy Pomphrey, chairman of VSD Avenue, explains The £82m contract, signed in July, was commissioned by the client and site owner the East ...

  • Combining thermal treatment with MNA at a brownfield DNAPL site

    Abstract A heavily contaminated Brownfields site in New York was remediated and redeveloped using a combination of In-Situ Thermal Desorption and Monitored Natural Attenuation. Four source areas were addressed by the thermal technology, and groundwater beneath the site is undergoing natural attenuation. Approximately 86,000 lbs of volatile organics were extracted and treated on-site. The ...

  • In-Situ thermal treatment of MGP waste and creosote

    Abstract: Remediation of coal tar at former Manufactured Gas Plant (MGP) sites, and creosote associated with wood preservative sites is challenging due to the viscous nature of the dense non-aqueous phase liquid (DNAPL) and the modest solubility and vapor pressure of the contaminants of concern (COCs). DNAPL seepage into surface water bodies, as well as groundwater plumes formed by the most ...

  • Mississauga Case Study (In Situ Gas Thermal Remediation (GTR™))

    In Situ Thermal Desorption in conjunction with soil vapor extraction was used to remove volatile organic compounds which contaminated the groundwater and saturated soil areas of a former metal fabricating facility in Ontario, Canada. The site had VOCs detected above the Canadian water standard in various monitoring well locations.  The remediation goal was achieved in 84 days and saw a 98% ...

  • Data Requirements for Soil, Sediment, and Sludge

    Site soil conditions frequently limit the selection of a treatment process. Process-limiting characteristics such as pH or moisture content may sometimes be adjusted. In other cases, a treatment technology may be eliminated based upon the soil classification (e.g., particle-size distribution) or other soil characteristics. Soils are inherently variable in their physical and chemical ...

  • Common Treatment Technologies for Fuels in Soil, Sediment, and Sludge

    Common treatment technologies for fuels in soil, sediment, and sludge include biodegradation, incineration, SVE, and low temperature thermal desorption. Incineration is typically used when chlorinated SVOCs are also present with fuel, and not specified for fuel-only contaminated soil, sediment, or sludge. All types of biodegradation, both in situ or ex situ, can be used to remediate soils: ...

  • Remediation of hydrocarbon contaminants from oil lagoons and refinery waste - case study

    In 2007 econ delivered an indirectly heated thermal desorption plant to a client in Kuwait. The plant is de-signed to treat various types of waste with hydrocarbon contaminant content. In particular refinery waste, oil lagoons and down hole drilling waste. The aim is to recover the waste hydrocarbons from the soil/sand and remediate the lagoons of their contaminants.  Due to the natural ...

  • Common Treatment Technologies for Halogenated VOCs in Soil, Sediment and Sludge

    Soil vapor extraction (SVE), thermal desorption, and incineration are the presumptive remedies for Superfund sites with halogenated VOC-contaminated soil. Because a presumptive remedy is a technology that EPA believes, based upon its past experience, generally will be the most appropriate remedy for a specified type of site, the presumptive remedy approach will accelerate site-specific analysis ...

  • Common Treatment Technologies for Nonhalogenated VOCs in Soil, Sediment and Sludge
