  • 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 ...

  • Thermal Treatment Technologies

    Hot gas decontamination: Hot gas decontamination is a technology still in the pilot-scale of development that can be used for decontamination of explosives-contaminated masonry or metallic structures. The method involves sealing and insulating the structures, heating with hot gas stream to 260 °C (500 °F) for a prescribed period of time, volatilizing the explosive contaminants, and destroying ...

  • Determining Proper Cooling Tower Size

    To maximize water-based cooling tower benefits, the appropriate tower size must be selected, requiring the identification of several critical factors. Cooling towers are a relatively inexpensive and reliable way of expelling heat from a number of industrial processes, including nuclear & thermal power plants, petroleum refineries, petrochemical plants, food processing plants, as well as HVAC ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Thermal treatment of thick peat layers – DNAPL removal and shrinkage

    Abstract A PCE DNAPL source zone was treated using thermal conduction heating combined with multi-phase extraction. Thick peat layers, even when contaminated with PCE DNAPL, were remediated to average soil PCE concentrations of 0.17 mg/kg (99.6% reduction compared to starting levels). This was accomplished in 83 days of heating, by elevating the temperature to the boiling point of water, and ...

  • 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 ...

  • The potential for thermal energy recovery from wastewater treatment works in southern England

    This paper asks how much heat could be recovered from wastewater treatment plants under UK climatic conditions, and can this heat be used effectively to reduce their carbon footprint? Four wastewater treatment sites in southern England have been investigated and the available heat quantified. Issues relating to the environmental, economic and practical constraints on how this energy can be ...

  • Application Guide for Thermal Desorption Systems

    EXECUTIVE SUMMARY Systematic guidance information on various currently available thermal desorption systems is not readily available. The purpose of this Application Guide is to provide (1) technical information on, design and performance characteristics, cost, associated regulatory compliance issues, and contracting strategies for deploying thermal desorption systems, and (2) to establish a ...

  • 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 ...

  • What’s the Temperature? Thermal Modeling and its Importance in Thermal Remediation

    What is a model? A beautiful person who struts down a run way, a scaled down sculpture of the Empire State Building, or a series of equations that describe some phenomenon? Did you guess all of the above? Gold star! Models come in many different shapes and sizes. In the environmental consulting and remediation industry, the word “model” often refers to a numerical model. Numerical ...

  • 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, ...
