    Sites where halogenated VOCs may be found include burn pits, chemical manufacturing plants or disposal areas, contaminated marine sediments, disposal wells and leach fields, electroplating/metal finishing shops, firefighting training areas, hangars/aircraft maintenance areas, landfills and burial pits, leaking collection and system sanitary lines, leaking storage tanks, radioactive/mixed waste ...

  • Standard Chlorine of Delaware Remediation

    By designing a 70-foot deep barrier wall, Black & Veatch was able to cut off contaminant source areas from a creek near New Castle, Delaware. The groundwater treatment system that Black & Veatch designed prevents site contamination from reaching the underlying drinking water aquifer. The Standard Chlorine of Delaware Site is a 65 acre area including an abandoned chlorobenzene ...

  • Chlorinated solvents: methylene chloride and TCE

    Introduction This paper presents the results of a scaled and phased approach to source remediation of high concentrations of recalcitrant chlorinated solvent compounds via soil vapor extraction (SVE) and vapor treatment at a Site in Southern California. Phase I began with refrigerated condensation (C3) in order to achieve high mass removal rates to reduce lifecycle costs and time ...

  • Electrical heating for the removal of recalcitrant organic compounds

    ABSTRACT This paper presents a remediation technology that combines electrical heating of the soil with extraction to achieve removal of vapour pressure sensitive compounds, such as chlorinated solvents, volatile and semi-volatile organic compounds, and heavier hydrocarbons. This technology is commercially known as the Electro-Thermal Dynamic Stripping Process (ET-DSP). As well the ...

  • Monitor Volatile Organic Compounds (VOC’s) with PPM Technology’s IAQ Monitor

    Volatile organic compounds (VOC’s) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors. VOC’s is one of numerous sensor options that can be incorporated into PPM Technology’s ...

  • Mechanical treatment of automobile shredder residue for its application as a fuel

    Enforcement of the Automobile Recycling Law in Japan requires utilization of automobile shredder residue (ASR). However, the high contents of copper (~5%) and chlorine (~1%) in ASR stand in the way of practical application. We studied methods for the removal of copper and chlorine from ASR so that it could be utilized as a fuel. By compression of the ASR for solidification with an extruder, the ...

  • Effective treatment of MtBE and breakdown products using C-Sparge and Perozone®

    Ozone oxidation systems like C-SpargeTM (microbubble ozone) and Perozone® (peroxide-coated ozone) are used for treatment of a variety of contaminants. From non-volatile to volatile compounds, from saturated to unsaturated compounds. The most common contaminants treated are chlorinated solvents, petroleum products and PAHs. Engineered microbubble systems with ozone (C-SpargeTM) or a combination of ...

  • 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 ...

  • Treatment of 1,4-Dioxane in Stockton, CA

    In the early 1990’s, the volatile organic compounds (VOCs) tetrachloroethylene (PCE) and trichloroethylene (TCE) were discovered in the vicinity of several city water supply wells near the city of Stockton, California. An aggressive, hydraulic containment/water reinjection system was installed to contain the plume and protect the quality of the drinking water. For several years, a treatment ...

  • New Treatment Technology Targets TOC/DOC Removal at Florida Utility

    Turn on any tap in Palm Springs, FL, and you will get crystal clear water. It has no odor, no metallic taste and compares favorably with most bottled waters. The residents are, quite naturally, very happy with it. Getting clean, refreshing water in Palm Springs was not an easy task. The ground water supply in South Florida typically contains large amounts of total organic carbon (TOC) in the ...

  • Full-scale SVE system operates in tandem with groundwater treatment

    Since 1993, SVE has been implemented using two designs at the TP Industrial, Inc. (TPI) site in Gardena, CA, to treat soil contaminated with chlorinated solvents. The SVE system was modified in 1997 to improve emissions control efficiency by using carbon adsorption units that treat effluent from an air-stripping system for treating site ground water. By the end of 2007, SVE had removed a ...
