  • Comparison of a Regenerative Thermal Oxidizer to a Rotary Concentrator

    INTRODUCTION The regenerative thermal oxidizer (RTO) is a very durable, well-proven technology suitable for treating a wide variety of emission streams. However, The RTO may not be the most economical technology available. Two very common systems for treating emissions from coating and finishing processes are the RTO and the concentrator/ oxidizer system. To determine which system is best suited ...

  • Very large waste gas volumes with low contaminant concentration - Case Study

    Example: Electronics industry Similar tasks: Paint shops, spectacle coating, coating on the inside of cans The electronic industry produces semiconductors that generate very large waste gas streams that are only slightly contaminated. These waste gas streams are purified in rotary adsorbers. The continuous regeneration of the adsorbers generates highly contaminated ...

  • Enhanced Bioremediation of High Contaminant Concentrations in Source Residual Area (PDF)

    Although enhanced bioremediation has proven to be effective at many sites, typically it has been applied to relatively low contaminant concentrations and in relatively permeable media. The project site described herein is an application that potentially extends the practical limits of in situ bioremediation applications. An active eyewear manufacturing facility located in Western NY was found to ...

  • Analytical and experimental study on bending vibration of internal combustion engines shafting system based on wave equations

    This paper proposes a new analytical approach to study the bending vibration of N step shafting system. Changes of the shaft step properties under rotary condition are governed by two–dimensional wave equations. The source of the bending vibration is first analysed. Then strain and stress equations of the spinning shaft are established. After Hamilton principle is applied, a two–dimensional wave ...

  • Phthalates: W.R. Grace - Dewey & Almy Chemical Division, New Jersey, USA

    Project Ex situ Treatment of Soils Impacted with Bis (2-ethylhexyl) phthalate Summary Soil impacted with bis (2-ethylhexyl) phthalate (BEHP) was treated ex situ in two covered land treatment cells containing approximately 450 yards of excavated soil. Concentrations of BEHP as high as 7,710 mg/kg, were reduced by 91.1% to 99.5% following 10 months of active ...


  • PaHs: Domtar Former Wood Preserving Site - Trenton, Ontario, Canada

    Project Bioremediation of Polycyclic Aromatic Hydrocarbon (PAH) & Pentachlorophenol Summary Soils impacted with PAH and Pentachlorophenol were treated in situ and ex situ in an independent study for the US EPA Superfund Innovative Technology Evaluation (SITE) program. The in situ treatment plot’s initial mean PAH concentration was 118.0 mg/kg. Chlorophenol ...


  • PaHs:Hamilton Harbour, Ontario, Canada

    Project Bioremediation of sediment impacted with PAHs Summary The effectiveness of DARAMEND® bioremediation was demonstrated on 150 tons of sediment dredged from PAH impacted regions of Hamilton Harbour. The harbour is adjacent to a heavily industrialized area and the sediments have been impacted with a variety of contaminants including residue from coal coking ...

  • Pyrolysis

    Introduction: Pyrolysis is formally defined as chemical decomposition induced in organic materials by heat in the absence of oxygen. In practice, it is not possible to achieve a completely oxygen-free atmosphere; actual pyrolytic systems are operated with less than stoichiometric quantities of oxygen. Because some oxygen will be present in any pyrolytic system, nominal oxidation will occur. If ...

  • Bioremediation replaces “dig and dump” for treatment of pesticides in soil

    Historical usage of organochlorine pesticides (OCPs) such as DDT, toxaphene and dieldrin has resulted in long-term soil contamination, because these substances typically do not degrade naturally at significant rates, so sites are still impacted decades after the end of application. For example, DDT use in Canada ended over 30 years ago, but impacted soil remains at many sites. Such was the case ...
