  • Ivey-sol technology has potential to increase oil recovery of oil-sands waste by 15-25 percent

    Alberta’s oil sands are comprised of one of the world's largest sources of bitumen, containing an estimated 1.6 trillion barrels. About two tonnes of oil sands must be dug up and processed to produce one barrel of oil. Oil sands recovery processes include extraction and separation systems to remove bitumen from sand and water. Separating the oil from the sand is difficult and costly, and getting ...

  • How to Optimize Oxidation Systems for Efficient Operation

    Emphasis on air management within converting-process dryers and ovens is critical to the design of pollution-control systems for treating exhausts containing VOCs (volatile organic compounds). Efficient air management allows the pollution-control system to be optimally sized to meet the needs of the process. Good process control further defines the emission stream by avoiding the need for large ...

  • Case study - Coater replaces old oxidizers With energy efficient systems

    Overview Emission control and the operating costs associated with meeting environmental regulations were nothing new for the Coated Products Division of Brady Corp. The company has been manufacturing coated films for nearly 60 years, demonstrating over that time a commitment to pollution prevention and emission reduction programs. But these considerations were magnified ...

  • 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 ...

  • Replacement of Hot Caustic Paint Stripping Process with High Pressure Water Jet System: Ford Australia

    Ford Australia Ltd replaced an existing hot caustic paint stripping process, used for cleaning car skids, with a high pressure water jet system. This project has resulted in annual savings in the order of $300,000 from reduced chemical, energy and waste disposal costs. Significant improvements in paint quality were also achieved through the ability to clean the skids on a more regular basis than ...


  • Treatment of industrial wastewater

    All industries produce some type of waste product, either from production, maintanance or both. These hazardous and non-hazardous wastes need to be properly stored, treated and discharged to a sewer system or otherwise disposed of. Wastewater treatment is a multi-stage process to renew wastewater before it is discharged to the municipal sewer system. The goal is tio reduce or remove organic ...

  • Thermal Desorption Unit - Overview, Types and Applications

    Thermal desorption is basically a remediation technique heavily used to clean contaminated soils, sludge’s etc. This technique uses heat to vaporize the contaminants, and works only for volatile contaminants. These include typically organic wastes composed of hydrocarbons, such as coal tar wastes, chlorinated solvents, oil refining wastes, fuels, pesticides, and a lot other. In the process, ...

  • The search for water contamination can create hazards of its own

    It''s a paradox. Most of the very technologies being used today to test water for contaminants actually return more pollution to the environment than the tested water itself. Nevertheless, as we all know, water testing is crucial to our health. Modern industry has unleashed tens of thousands of chemicals into the environment. Many of these chemicals are essential, but it''s the control of them ...

  • Power plants use oil skimmers to prevent contamination from spills

    Most hydroelectric plants designed in the 1960s were built with a station drainage sump that collects all drainage from the plant. As designed, float switches activate sump pumps that discharge liquids directly into the tailrace. The system cannot distinguish between types of liquids, so in the event of an oil leak, oil in the sump could be released into the tailrace. Modern ...

  • A method for reducing purge volumes in deep monitoring wells: a purging experiment.

    Regulatory agencies often require three well casing volumes or more be purged prior to collection of groundwater samples for chemical analysis. Costs are high for testing and disposing of potentially hazardous purge water; therefore, efforts must be made to minimize waste-water volume while obtaining representative groundwater samples. Lockheed sponsored a purge experiment on two deep monitor ...

  • Will your oil in water analysis method match the regulatory method?

    Anyone involved in field analysis of oil in water will continually get the question “Does your equipment match the regulatory method?” While the amount of oil in water is highly regulated -- it can also be a challenging measurement. It is complicated by the fact that oil comes in many forms and the measurement is defined by the particular regulatory method. When EPA 1664 is the ...
