  • 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 ...

  • Andover, Vapor Extraction and Refrigerated Condensation Case study

    Vapor Extraction and Refrigerated Condensation was used as a primary source removal technology to remediate high concentrations of recalcitrant chlorinated solvent compounds at the WDE Site in Minnesota. The use of Refrigerated Condensation has achieved high mass removal rates and will reduce the lifecycle costs and time of remediation. History 6,600 drums of hazardous ...

  • In-well Vapor Stripping - Technology Overview

    In-well vapor stripping technology involves the creation of a ground-water circulation pattern and simultaneous aeration within the stripping well to volatilize VOCs from the circulating ground-water. Air-lift pumping is used to lift ground-water and strip it of contaminants. Contaminated vapors may be drawn off for aboveground treatment or released to the vadose zone for biodegradation. ...

  • Vapor Steamers for Tile and Grout Maintenance

    Tile and grout cleaning is undoubtedly a tiresome and time-consuming job. Tiled floors are normally used in areas that experience heavy traffic. As a result, the floors can get quite dull and dirty at the end of the day. Then, there is the issue of grout, a highly porous surface that quickly absorbs dirt and develops stains. Rigorous scrubbing can wear away the grout and spoil its appeal. For ...

  • Vapor intrusion mitigated through solar-powered exhaust systems

    EPA Region 6 undertook a Superfund removal action earlier this year at the Delfasco Forge site in Grand Prairie, TX, to address trichloroethene (TCE) vapor migrating from a groundwater plume. Region 6 and the State had determined after extensive site investigations that technologies such as soil vapor extraction or natural attenuation would require several years to remove or reduce the plume ...

  • Taking Fossil Fuels to the Next Level - Standards Underpin Extraction, Processing and Distribution

    To the average person, the oil and gas industry may appear simple — a matter of literally tapping into a natural resource and distributing it to customers. Of course the matter of extraction is rarely simple, and in the case of emergent hydraulic fracturing technology, it is particularly complex and capital-intensive. In fact, the world of petroleum and natural gas extraction, distribution ...

  • Bioslurping - Technology Overview

    ABSTRACT Bioslurping involves the simultaneous application of vacuum enhanced extraction/recovery, vapor extraction, and bioventing to address LNAPL contamination. Vacuum extraction/recovery is used to remove free product along with some groundwater, vapor extrac tion is used to remove high volatility vapors from the vadose zone, and bioventing is used to enhance aerobic biodegradation in the ...

  • Horizontal Wells - Technology Overview

    Horizontal well technology has been incorporated into many current environmental remediation applications (and associated contaminants), such as in situ bioremediation, air sparging, vacuum extraction, soil flushing, free product recovery, etc. Ac cording to information reviewed, this technology is most applicable to sites with relatively shallow soil and/or groundwater contamination, and can ...

  • Common Treatment Technologies for Nonhalogenated VOCs

    Soil vapor extraction (SVE), thermal desorption, and incineration are the presumptive remedies for Superfund sites with nonhalogenated 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 ...

  • Thermal Desorption - A Viable Solution

    Untitled Document As regulations continue to tighten, the need for expedient and accurate remediation technology is of great importance. When faced with the demand or need to reach ...


  • 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: ...

  • Steam Enhanced Creosote Pumping - Case Study

  • Enhancing the Versatility of Steam Cleaners with Dry Steam Cleaners

    Steam cleaning machines are powerful cleaning systems that utilize the amazing action of hot steam to clean a large number of surfaces. Although hot steam is aggressive on dirt deposits, it is very gentle on surfaces. For this reason, it is great for use even on surfaces that can be damaged by harsh chemicals or high pressure levels. This makes steam cleaning equipment perfect for maintaining ...
