  • Sensitivity of ozone and aerosols to precursor emissions in Europe

    We modelled the air quality in Europe during January and June 2006 using the MM5/CAMx model system and studied the sensitivity of ozone and aerosol formation to precursor emissions. Increased isoprene emissions by a factor of four in summer caused an increase in afternoon ozone by up to 10%. On the other hand, the effect on secondary organic aerosols (SOA) was very small. Reductions in ...

  • Case study - Oil and gas production

    Problem The largest U.S.-based independent oil and gas producer and one of the largest independent processors of natural gas and natural gas liquids in North America was in search of new technologies to maintain the pollution control efficiency at their natural gas treatment facility. In typical gas plants, the well head natural gas needs to be treated to remove water, CO2, any ...

  • Case study - Pemaco superfund site remediation

    OVERVIEW Pemaco was formerly a chemical facility located in a light industrial and residential area of Maywood, CA, adjacent to the Los Angeles River. No one knows how long hazardous substances had been leaking into the ground but the operations date back to the 1940's.  Up until closure of the facility in 1991, chlorinated solvents, aromatic solvents, and flammable liquids had ...

  • Case study - Wind turbine manufacturer implements clean air initiative

    Overview When you think about generating electricity from wind, clean energy comes to mind. However, the wind turbine production process can be a major source of air pollution without the proper controls in place. Manufacturing and painting the blades, towers and nacelles requires composite construction material and solvent based coatings. The potential to emit Volatile Organic Compounds ...

  • Case study - Standardization: a breath of fresh air for Anguil Environmental Systems

    OEM reduces engineering costs by 50 percent through standardizing on the Rockwell Automation® Logix control BACKGROUND According to the United States Environmental Protection Agency (EPA), each year millions of tons of air toxins are released into the air, mostly from man-made sources. Anguil Environmental Systems Inc., a Milwaukee-based air pollution ...

  • Ultra-trace arsenic speciation at Columbia Analytical

    Ultra-trace speciation of arsenic and other metals is performed using a variety of techniques tailored to the specific combination of species, matrix, and detection limits required. Currently, two analytical systems are applied: Ion Chromatography-Inductively Coupled Mass Spectrometry (IC-ICP-MS) and Hydride Generation-Cryogenic Gas Chromatography-Flame Atomic Absorption Spectrometry ...


  • Costs of air pollution from European industrial facilities – an updated assessment

    In 2011, the European Environment Agency (EEA) published a first assessment of the costs of air pollution caused by European industrial facilities. The report Revealing the costs of air pollution from industrial facilities in Europe (EEA, 2011) applied a simplified modelling approach to assess the damage costs to health and the environment in 2009, caused by pollutant emissions from industrial ...

  • The Progression of Remediation

    Environmental remediation involves the cleanup of contaminated ground water and/or soils impacted by a variety of contaminates. The predominate contaminates over the years have been petroleum hydrocarbons from leaking underground storage tanks and surface spills, as well as solvents and other volatile organic compounds (VOCs) from industrial processes. Today, the most effective, practical, and ...

  • 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 ...

  • LNAPL remediation using electrical resistance heating

    Abstract An Electrical Resistance Heating (ERH) pilot test was conducted in the fall of 1998 to determine the effectiveness of using ERH in combination with soil vapor extraction (SVE) for the remediation of benzene and light nonaqueous-phase liquids (LNAPL) at an island location on a river in the Midwest. Hydrocarbon-stained soils were discovered on an island in Ohio in May 1993 during the ...

  • Pilot tests lead to full-scale ISCO using sodium permanganate in fractured bedrock

    Two-phase pilot testing of in-situ chemical oxidation (ISCO) using sodium permanganate (NaMnO4) was conducted in 2000-2001 at the Tenneco Automotive site in Hartwell, GA, to evaluate feasibility of using ISCO to remediate a dissolved-phase trichloroethene (TCE) plume in a fractured bedrock aquifer [see May 2004 TNT]. The ISCO pilot was initiated to develop an alternate remedy for the off-facility ...

  • Solar Detoxification

    Introduction: In this process, vacuum extraction is used to remove contaminants from soils. After condensation, contaminants are mixed with a semiconductor catalyst such (e.g., titanium dioxide), and fed through a reactor which is illuminated by sunlight. Ultraviolet light activates the catalyst, which results in the formation of reactive chemicals known as 'radicals'. These radicals are ...

  • Air pollution in Europe 1990-2004

    Overall picture This report analyses and presents changes in air pollutant emissions and their possible health or ecosystem impacts in Europe covering the period 1990–2004. Emissions of all air pollutants fell substantially during the period 1990–2004 in the 32 EEA member countries (EEA-32), resulting in improved air quality over the region. However, ambient concentrations of particulate ...

  • Project profile - Blue Rhino Hamptonville, NC

    Background In 2007, Blue Rhino, located in Hamptonville, NC, contacted AdEdge Technologies, Inc. (AdEdge) to install an iron and manganese treatment system. The amount of iron (5.6 mg/L Fe) and manganese (0.6 mg/L Mn) were well above the maximum contaminant levels of 0.3 mg/L Fe an 0.05 mg/L Mn respectively. The pH of the Blue Rhino site (6.10) was quite below the maximum contaminant ...

  • Metal Coating Emission Control

    The use of regenerative thermal oxidizers is expanding into applications where they wouldn’t have been considered years ago, says Mike Scholz As the first generation of oxidizer systems in the industry nears the end of their service life, many canmaking plants face repair or replacement of their existing air pollution control systems. Like many others in the industry, a Silgan canmaking ...
