  • Overheating Damage at Activated Carbon Filter

    At one of the DMT’s plants recently a safety incident occurred. An Activated Carbon Filter overheated due to an incorrect mode of operation, causing damage to the installation. This led to a significant financial loss including business interruption impacts. To raise awareness for correct operation of Activated Carbon Filters, DMT publishes this S.H.E. bulletin to prevent this from ...

  • TCE plume management through edible oil injection and natural attenuation

    Two pilot-scale edible oil barriers were constructed in the upper portion of a 1,500 m long chlorinated solvent plume at Dover Air Force Base (AFB), DE. Edible soybean oil was injected into two 6.1 m-long barriers with monitoring wells spaced up to 4.6 m downgradient. Barrier 1 was treated by low pressure, direct injection of soybean oil into ten wells spaced 0.6 m apart. After eight months, a ...

  • Innovative Injection Technique to Treat DNAPL in Granular and Fine Grained Matrices

    High Energy low volume pulses of a water based suspension of a unique treatment material (BOS 100) consisting of granular activated carbon that has been impregnated with metallic iron were employed to remediate DNAPL at a large urban industrial facility. Initially, injections were completed using conventional hydraulic fracturing and large portions of the dissolved phase plume responded to this ...

  • ISCR-Enhanced Bioremediation Accelerates Groundwater Cleanup at Active Manufacturing Facility

    In the winter of 2008, full-scale in situ chemical reduction (ISCR) was implemented as a removal action at the Siltronic Corporation site in Portland, OR, to treat a source area contaminated by releases of TCE. The source area was considered to be the portion of the site with concentrations of TCE in groundwater greater than 11,000 µg/L, suggesting the ...


  • Liability and financial responsibility frameworks for carbon capture and sequestration

    Carbon dioxide capture and sequestration (CCS) is an important option for reducing CO2 emissions from human activities.  There is growing interest in CCS as renewable energy and energy efficiency alone are unlikely to deliver the emission reductions necessary to stabilize atmospheric concentrations of greenhouse gases by mid-century.1 CCS involves capturing CO2 generated from fossil fuel ...

  • Waste Gas in Metal Recycling: Hydrocarbons and carbon monoxide - Case Study

    Example: Aluminium recycling Similar tasks: Recycling of copper, lead, cink The waste gas in metal recycling usually contains particles (abraded metal, mineral dust), inorganic, acid substances (HF, HCI, SOx) and dioxins (PCDD/F) as well as a whole range of organic substances (unburned hydrocarbons) and carbon monoxide. Particularly, in the group of unburned ...

  • Enhancement of Terrestrial Carbon Sink Potential: A Possible Contribution to Mitigating Global Warming

    Introduction Climate researcher Klaus Hasselmann, Director of the Max-Planck-Institut (MPI) for Meteorology in Hamburg and a project co-ordinator of EC’s Environment and Climate Programme, was one of the first scientists to warn that recently observed global warming trends have a discernible human related forcing component. Climate model calculations show, that global warming is closely related ...


  • Greenhouse Gas Accounting Framework for Carbon Capture and Storage Projects

    Foreword Meeting the global challenge to reduce greenhouse gas (GHG) emissions and avoid dangerous climate impacts requires deploying a portfolio of emission reduction technologies. We must both commit to broad and deep efficiencies in the way our societies’ consume energy and to significant increases in power supplies from low carbon energy sources. At the same time, it ...

  • Blacks dry cleaner Tetrachloroethene remediation project

    Background PCE source area in soil and groundwater at an active dry cleaner. Performed demonstration of Bioavailability Enhancement Technology (B.E. T.rM patent pending). B.E. T.  is a source area bioremediation technology that enhances the dissolution of the chlorinated solvent contaminant and provides an electron donor for anaerobic reductive ...

  • VIGNEUX, France: Grand Systeme–Elimination of turbidity and microbiological retention

    Water is mostly taken from the Seine and then processed in three plants: Vigneux sur Seine, the most innovative, Morsang sur Seine, and Viry Châtillon. The Vigneux treatment plant is thus the link in a chain entirely dedicated to quality. Between 1993 and 1997, the facilityacquired a high-performance ozoning unit and an innovative water refining process, the Ultrafiltration by membranes combined ...

  • Case study – benzene contamination retail gas station, Colorado

    Introduction The scope of work for this site included an expansion of an existing soil venting system to remediate impacted soil and injection of a carbon-based petroleum degrading product to remediate long-term groundwater impacts. By using a combination of remediation technologies, including LT Environmental’s (LTE) TerraCert™ program, the overall goal of a cost effective cleanup ...

  • Comparative Effects of HRC Application at Four Project Locations (PDF)

    Four site locations in the Southern or Midwest United States were the venues for pilot testing of a commercially available injectable bioremediation product (HRC™) to enhance the reductive dechlorination of chlorinated solvents. This activity occurred from 1997 through the end of 2000. Prior to injection, each site exhibited bioattenuation of parent compounds such as PCE, TCE, carbon ...

  • SVE and Air Sparging

    Stage 1: The system is a PLC controlled plant equipped with telemetry. Rotary Lobe blowers were used to abstract vapour contaminated with chlorinated hydrocarbons and a similar high pressure blower was used to inject air via solenoid valves individually controlled by the PLC. Extracted vapour was treated in large GRS 2 tonne vapour-phase activated carbon vessels.Stage 2: The system comprised ...


  • Source area bioremediation of chlorinated solvents with edible oils emulsion

    Groundwater in a sand and gravel aquifer beneath this active manufacturing facility was contaminated with high concentrations of 1,1,1- Trichloroethane (1TCA) and cis-1,2-dichloroethene (cDCE), and their degradation products including ethene and ethane. An acclimated anaerobic microbial population was present at the site, but was limited by the availability of carbon. Emulsified edible oil was ...

  • Combined use of ISCO and ISCR to treat CVOCs at industrial site in Texas, USA

    Groundwater at an industrial site in Texas is impacted with Chlorinated Volatile Organic Carbon’s (CVOCs), primarily PCE and TCE, from historical waste disposal. The topography at the site slopes steeply towards a small channel where the groundwater discharges. Depth to groundwater ranges from approximately 20 ft bgs at the source area to 1 ft bgs close to the channel. The soil consists of silty ...


  • How To: Bioremediate chlorinated solvents without accumulating metabolites

    Chlorinated volatile organic compounds (CVOCs) such as tetrachloroethylene (PCE) and trichloroethylene (TCE), commonly used as dry cleaning solvents and degreasers, pose an ongoing threat to human health and wildlife when spilled into groundwater. Through the injection of bioremediation products into the impacted groundwater, the chlorine atoms can be removed from these compounds in situ. ...


  • A Pilot Study of Mercury Liberation and Capture from Coal-Fired Power Plant Fly Ash
