  • Vinyl Chloride Attenuation By Direct Injection of Time-Release Magnesium Peroxide.

    ABSTRACT: This case study shows that there is potential to remediate dissolved vinyl chloride by oxygenation in the field. Residual vinyl chloride concentrations have been remediated in the field at a mid-western site with a phosphate-intercalated peroxygen (ORC®, a proprietary formulation of magnesium peroxide that releases oxygen slowly). The site was formerly operated as an aluminum coating ...

  • On the over-investment in automotive technology

    This paper discusses the reasons for continuing very high levels of R&D spending in the automotive industry in spite of the fact that both the automobile and the market for automobiles are widely considered to be mature. Most R&D appears to be product and not process-related. The microelectronics revolution has to some extent rejuvenated the automobile. Besides that, government regulation has ...

  • Technology: clean air’s unsung hero

    Last year, we celebrated the 40th anniversary of the U.S. Clean Air Act (CAA) and the 20th anniversary of the 1990 Amendments to the CAA. The CAA has been a huge success. From 1990 to 2008, emissions of six common pollutants were down 41%, while gross domestic product grew 64%. Emissions of volatile organic compounds dropped 31%, carbon monoxide dropped 46%, and sulfur dioxide dropped 51%. Lead ...

  • Application of Membrane Technology for the Recovery and Reuse of Water

    Abstract As water and sewer costs are expected to increase over the next decade, membrane technology will continue to be a viable and economical option in the recovery and reuse of water. This paper describes the mechanism of membrane effected separation (specifically reverse osmosis, ultrafiltration and microfiltration), membranes commercially available, membrane element configurations, and how ...


  • New environmental management technology meets demanding needs of E&P clients

    Exploration & Production companies are constantly pushing the envelope in terms of performance, because increased performance has a direct translation into increased revenue. E&P companies are under tremendous pressure to produce, both to meet growing demand as well as to take advantage of market prices. At the same time companies are also under increasing pressure to meet the ...

  • DNAPL Characterization Methods and Approaches, Part 2: Cost Comparisons`, Ground Water Monitoring & Remediation

    Contamination from the use of chlorinated solvents, often classified as dense nonaqueous phase liquids (DNAPLs) when in an undissolved state, pose environmental threats to ground water resources worldwide. DNAPL site characterization method performance comparisons are presented in a companion paper (Kram et al. 2001). This study compares the costs for implementing various characterization ...

  • The analysis of auto industrial clusters competitiveness in China in the context of economic globalisation

    The paper mainly discusses the impacts of economic and market globalisation on the international competitiveness of China auto industrial clusters through three relative aspects: opening market, FDI effects and global management strategy. With the process of the integration with the whole global value chain, the new value point can be innovated and obtained; the implementation of the FDI strategy ...

  • Enhanced Bioremediation of Chlorinated Solvents (PDF)

    Enhanced in situ bioremediation of chlorinated solvents in groundwater has been successfully demonstrated at many sites by supplying lactic acid as an electron donor. The source of lactate for these successful pilot tests is Hydrogen Release Compound (HRC), a polylactate ester specially formulated for slow release of lactic acid upon hydration. HRC has been delivered to chlorinated ...

  • 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 ...

  • Who says you need multiple wire breaks for a PCCP pipe to fail?

    Abstract On Sunday, October 5, at about 2:30 a.m. a section of 72-inch prestressed concrete cylinder pipe (PCCP) failed. The 72-inch-diameter PCCP was nominally capable of sustaining an internal pressure of 281 psi. Previous examinations of the pipeline, utilizing the best available nondestructive examination techniques, provided little indication that this pipe section was at risk of ...

  • Systems approach - Petroleum site

    An 18-month, in-situ biological program, specifically aimed at accelerating the current attenuation process such that the owner can sell the property began May 5, 2000.
