  • LNAPL remediation using electrical resistance heating

    Abstract An Electrical Resistance Heating (ERH) pilot test was conducted in the fall of 1998 to determine the effectiveness of using ERH in combination with soil vapor extraction (SVE) for the remediation of benzene and light nonaqueous-phase liquids (LNAPL) at an island location on a river in the Midwest. Hydrocarbon-stained soils were discovered on an island in Ohio in May 1993 during the ...

  • Electrical Resistance Heating: a Hot New Approach to Soil and Groundwater Remediation

    Electrical Resistance Heating (ERH) is an aggressive remediation technology that can quickly reduce the mass of volatile organic compounds (VOCs) in soil and groundwater by over 99%. The process is often used to clean sites where other technologies have had limited success. Larger ERH sites are cleaned within 6 to 12 months and smaller sites can be cleaned in half that time or ...

  • New Advancements for In Situ Treatment Using Electrical Resistance Heating

    Electrical resistance heating (ERH) is proving to be an effective technology to rapidly heat the subsurface and, in doing so, removing volatile organic compounds. Practitioners of this technology have observed that other processes (biodegradation, abiotic degradation, hydrolysis, and possibly others) occur to break down the chemicals of concern, and remediation is not solely accomplished through ...

  • In situ Remediation of 1,4-Dioxane using Electrical Resistance Heating

    An increasing number of states are establishing enforceable 1,4-dioxane cleanup goals due to recent improvements in analytical detection methods and existing carcinogenic risk information for 1,4-dioxane. Historically, 1,4-dioxane was used as a stabilizer for chlorinated solvents, primarily 1,1,1-trichloroethane. In addition, 1,4-dioxane has been used in a broad range of products including but ...

  • Enhanced In Situ Biodegradation of PCE Following Electrical Resistance Heating at a DNAPL Source Area

    Area of Concern (AOC) 607 is a former dry cleaner at the Charleston Naval Complex (CNC). During the RCRA field investigation (RFI), soil and groundwater were found to be impacted by tetrachloroethene (PCE). PCE concentrations in groundwater as high as 42,000 mircograms per liter (μg/L) were detected. During a nine-month period, an area defined by monitoring wells with PCE concentrations ...

  • Enhanced Removal of Separate Phase Viscous Fuel by Electrical Resistance Heating and multi phase Extraction

    Abstract A floating hydrocarbon plume at a manufacturing facility in Georgia was remediated using electrical resistance heating (ERH) and multi-phase extraction. The hydrocarbon was a specialty fuel similar to kerosene or diesel fuel. Initially, hydrocarbon covered an area of 4900 ft2 (500 m2) and was up to l0 ft (3 m) thick, with most wells containing 1-3 ft (0.5-1 m) of hydrocarbon. ...

  • In Situ Thermal Remediation of DNAPL and LNAPL Using Resistance Heating

    Electrical resistance heating (ERH) is an in situ thermal treatment for soil and groundwater remediation that can reduce the time to clean up volatile organic compounds (VOCs) from years to months. The technology is now mature enough to provide site owners with both performance and financial certainty in their site-closure process. The ability of the technology to remediate soil and groundwater ...

  • Three-Phase Heating? Six-Phase Heating? Which is Better?

    First off, both “three-phase heating” and “six-phase heating” are varieties of Electrical Resistance Heating (ERH) – there really isn’t that much difference between them. The skill of the electrode designers and the experience of the operators are far more important to the success of your project than is the number of electrical phases. Thermal Remediation Services uses the best phasing technique ...

  • In Situ Dechlorination of TCE during Aquifer Heating

    Laboratory and field efforts were undertaken to examine trichloroethene (TCE) dechlorination as a function of temperature as an aquifer is heated to temperatures approaching boiling. Experiments were conducted using sediment samples and during electrical resistance heating (ERH) treatment at the East Gate Disposal Yard (Fort Lewis, Washington), which contains nonaqueous phase TCE and hydrocarbon ...

  • In Situ electromagnetic heating for hydrocarbon recovery and environmental remediation

    Introduction Thermal recovery methods, as applied in heavy oil and oil sand deposits, and in environmental remediation, have the common objective of accelerating the hydrocarbon recovery process. Raising the temperature of the host formation reduces the oil and bitumen viscosity, and, in environmental remediation, increases vapour pressure. These effects assist in sweeping the substances ...
