  • Soil Vapor Extraction (In Situ)

    Introduction Soil vapor extraction (SVE) is an in situ unsaturated (vadose) zone soil remediation technology in which a vacuum is applied to the soil to induce the controlled flow of air and remove volatile and some semivolatile contaminants from the soil. The gas leaving the soil may be treated to recover or destroy the contaminants, depending on local and state air discharge regulations. ...

  • Removal of vehicle exhaust fumes at fire stations

    The challenge The fire brigade of Kassel (Germany) was looking for three new vehicle exhaust extraction systems. Systems that would remove exhaust fumes very effectively, protecting the fire fighters from hazardous diesel exhaust fumes. Other fire stations within the Kassel region were already provided with extraction systems. The fire brigade of Kassel choose for a fully ...

  • Pennsylvania air national guard uses exhaust removal system

    Monoxivent’s 9000-MTR Hose Reel was used to remove toxic exhaust fumes from military vehicles at the Pennsylvania Air National Guard. Monoxivent's motor-operated hose reels are the premier solution to exhaust extraction. They provide the answer for customers who have obstructions, which prohibit the use of other types of overhead-exhaust systems.  At the Air National Guard facility, ...

  • 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 ...

  • Tenax extraction as a simple approach to improve environmental risk assessments

    It is well documented that using exhaustive chemical extractions is not an effective means of assessing exposure of hydrophobic organic compounds in sediments and that bioavailability‐based techniques are an improvement over traditional methods. One technique that has shown special promise as a method for assessing the bioavailability of hydrophobic organic compounds in sediment is the use of ...

  • Wind-driven SVE system extracts VOCs from landfill

    An innovative soil vapor extraction (SVE) system has operated at the former Ferdula Landfill site in Frankfort, NY, for the past 10 years. The system relies on wind-driven vacuum processes rather than electrically powered air blowers to extract volatile organic compounds (VOCs) from the landfill. After a two-year trial beginning in 1998, the New York State Department of Environmental Conservation ...

  • Enrichment of oxygen-containing aromatics in an extract from Zhundong subbituminous coal

    Zhundong subbituminous coal (ZSBC) was exhaustively extracted with isometric carbon disulfide (CDS)/acetone mixed solvent to afford extract 1 (E 1 ), which was sequentially extracted with petroleum ether (PE) and CDS to afford extracts 2 (E 2 ) and 3 (E 3 ). E 3 was gradiently eluted into effluent portions 1 to 5 (EPs 1 to 5) through a silica gel-packed column ...

  • Extraction of many emission sources in extensive factory premises - Case Study

    Example: Packaging Similar tasks: Coating, Automobile industry, paint production Different production processes lead to decentralised ventilation of emission sources. These decentralised ventilations are consolidated within a central air pollution control system. A producer of plastic, cardboard and composite material packages uses a range of printing units, laminating machines ...

  • Class I, Division 1 Industrial Lights for THC Extraction Labs

    The cannabis industry is growing at a rapid rate. According to a report published by Marijuana Business Daily, the emerging sector is forecasted to overtake craft beer and organic food products. With legalization gaining momentum, it could reach $44 billion by 2020. The study also pointed out that for every dollar spent on weed, the local economy gains three dollars. A recent trend in marijuana ...

  • Understanding bioavailability and toxicity of sediment‐associated contaminants by combining passive sampling with in vitro bioassays in an urban river catchment

    Bioavailable and bioaccessible fractions of sediment‐associated contaminants are considered as better dose metrics for sediment‐quality assessment than total concentrations. The authors applied exhaustive solvent extraction and nondepletive equilibrium sampling techniques to sediment samples collected along the Brisbane River in South East Queensland, Australia, which range from pristine ...

  • Sustainable Development, Renewable Resources and Technological Progress

    Conflicts between optimality and sustainability are typical in the literature on sustainable development. Using the capital-resource growth model, Pezzey and Withagen (1998, Scandinavian Journal of Economics 100 (2), 513–527) have proved that if natural resources are exhaustible, the time-path of consumption is single-peaked, declining from some point in time onwards. This paper extends the model ...

  • Capital Accumulation and Resource Depletion: A Hartwick Rule Counterfactual

    How much produced capital would resource-abundant countries have today if they had actually followed the Hartwick Rule (invest resource rents in other assets) over the last 30 years? We employ time series data on investment and rents on exhaustible resource extraction for 70 countries to answer this question. The results are striking: Venezuela, Trinidad and Tobago, and Gabon would all have as ...

  • Determining trace amounts of contaminants in water

    Introduction Pesticides, polychlorinated biphenyls (PCBs), and pharmaceuticals are a worldwide contamination problem. Several major US water bodies, such as the Hudson River, St. Lawrence River, Fox River and the Great Lakes have been contaminated with PCBs from industries discharging into these water bodies for decades. For example, from approximately 1947 to 1977, the General Electric ...

  • Peak phosphorus - conserving the world`s most essential resource

    Abstract Phosphorus (P) is one of the three major plant nutrients but it is the scarcest on the planet; at the current rate of exploitation, today's resources will be exhausted in about 70 years; 80% of the extracted P is used as fertiliser. Additional reserves might last another 200 years; when they are exhausted, crop yields will decline rapidly. All living cells require P; it cannot be ...

  • Common Treatment Technologies for Halogenated VOCs in Soil, Sediment and Sludge

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

  • Industrial Wastewater Treatment: Priority pollutant behaviour in on-site treatment systems for industrial wastewaters

    The majority of wastewaters deriving from the chemical industry consist of aqueous discharges produced during the physico-chemical processing of synthetic mixtures involving operations such as filtration, centrifugation, extraction and/or distillation. The wastewater streams, referred to as ‘process waters’ can include mother liquors, washing waters from the purification of products, ...
