  • Thermally Enhanced Soil Vapor Extraction

    Introduction Thermally enhanced SVE is a full-scale technology that uses electrical resistance/electromagnetic/fiber optic/radio frequency heating or hot-air/steam injection to increase the volatilization rate of semi-volatiles and facilitate extraction. Thermally enhanced SVE is normally a short- to medium-term technology. Electrical Resistance Heating Electrical resistance heating uses ...

  • 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.

  • Thermal Remediation of Karst Limestone – Redstone Arsenal, Alabama

    Abstract: Electrical resistance heating (ERH) was used for the thermal remediation of two sites at Redstone Arsenal (RSA) near Huntsville, Alabama. Both sites feature karst limestone with heavy clay overburden. The two sites are located about five miles (10 km) apart, but differ considerably in the characteristics of the limestone. At site RSA-053, the heavy clay is underlain by very hard, ...

  • The Behavior at the Shrinkage Limit of Clay Undergoing Drying

    In this paper, possible links between the shrinkage limit and distinct changes in other properties of a clay soil undergoing drying are discussed. These properties include the volumetric air content of the soil, the heat of wetting, the tensile strength, the total suction, and the thermal resistivity of the soil. The distinct changes are of interest in themselves, and possible explanations for ...

  • Incineration

    Introduction: High temperatures, 870 to 1,200 °C (1,400 to 2,200 °F), are used to volatilize and combust (in the presence of oxygen) halogenated and other refractory organics in hazardous wastes. Often auxiliary fuels are employed to initiate and sustain combustion. The destruction and removal efficiency (DRE) for properly operated incinerators exceeds the 99.99% requirement for hazardous waste ...
