  • Nitrogen Demand Increases for Semiconductor: How Safe Are You?

    As users demand ever-smaller smartphones and better televisions, semiconductor manufacturing plants are tasked with developing new products faster and using new materials. Key to the continued success of the semiconductor industry are inert gases, which include nitrogen and argon. When used safely, both nitrogen and argon play a number of important roles within the semiconductor ...

  • Oxygen, the fix for pond problems

    Aeration of a water feature should have three main considerations. These include preventing thermal stratification, balancing the dissolved oxygen levels throughout the water column from the sludge or benthic layer to the surface and balancing temperature levels throughout the water column. Although oxygen transfer from certain methods may be significant, the greatest amount of oxygenation takes ...

  • ppb Dissolved oxygen measurement

    Dissolved oxygen (D.O.) measurement is one indicator of water quality because oxygen is a common element contributing to corrosion reactions. This corrosion reaction provides the need for low level D.O. control since dissolved oxygen is responsible for costly replacement of piping and equipment by corrosive attack on metah. what is Dissolved Oxygen? Dissolved axygan (D.O.f is the ...

  • On-site regeneration of transformer oil

    Regeneration of transformer oil at the transformer’s location is an important preventive measure of transformer servicing.   Transformer life time is, in essence, the life time of its insulation system. The most widely used insulation is liquid insulation (transformer oils) and solid insulation (paper, i.e. cellulose insulation). The oil provides for at ...

  • Oxygen Release Compound - Canada Case Study

    EHC-O Oxygen Releasing Compound - ES&E Magazine (May 2007) A whimsical comment by the author Michael McClary compels one to realize that more intuitive processes can be overlooked when considering technology’s abilities to improve our natural environments. He said: “Irrigation of the land with seawater desalinated by fusion power is ancient. It’s called rain.” In situ treatment of ...


  • In situ bioremediation of pentachlorophenol by dissloved oxygen injection

    ABSTRACT: In September of 1982 a faulty valve on a railroad tank car resulted in the accidental release of a wood treating solution containing pentachlorophenol. Subsequent investigations indicated that the wood treatment dip tank had also been a source of soil and ground water contamination. A ground water and product extraction system was installed soon after the rail car release, but after 13 ...

  • Ontario Landfill Site - Case Study

    A Texas based company with waste management sites around North America have installed electrical generation plants at various locations that use methane collected from the waste. The daily operation of these sites include the management of the leachate, a liquid waste by-product of decomposition, and the collection of gas for electricity production. This is typically carried out at multiple wells ...

  • Remediation of BTEX in Groundwater with LNAPL Using Oxygen Releasing Materials (ORM).

    Abstract: A field scale study was conducted at a former gasoline service station to evaluate the remediation of groundwater contaminated with dissolved benzene, toluene, ethylbenzene, and xylenes (BTEX) using oxygen-releasing materials (ORM). The injection of oxygen through ORM slurry was the remedial alternative chosen to enhance the in-situ microbial degradation of the BTEX in groundwater. ...

  • Study of Natural Bioremediation Projects Using Time-Release Oxygen Compounds.

    ABSTRACT: Enhanced natural bioremediation studies are being conducted on a series of sites throughout the midwest United States. Each site exhibits a unique geologic condition, contaminant concentration, enhancement application, and remediation goal. Based on a review of 14 sites, the usage and effectiveness of enhanced bioremediation has been categorized to provide general guidelines for ...

  • The East-Sullivan Mine Site: from Abandonment to Restoration

    The East Sullivan mine was closed in 1966, leaving 15 Mt of acid-generating tailings free to contaminate the environment. An experimental wood waste cover was implemented in the early 80's in order to prevent sulphide oxidation. Contaminant production and dispersion were investigated in the 90's to validate that concept and guide later actions. Ligneous wastes stop oxygen, and also favour ...

  • Utilisation of landfill gas for the generation of energy

    The gases in landfill sites that develop during degradation processes, largely contribute to the greenhouse effect and additionally harbour considerable safety and health hazards. However, they are also often rich in methane and therefore a potential energy carrier. In many countries much of this potential for the generation of electricity and heat from landfill gas still exists. Furthermore, ...

  • E.On on-site sewage treatment plant (Ratcliffe-on-Soar)

    Located in Nottinghamshire, E.On's Ratcliffe-on-Soar facility is one of the most efficient coal fired power stations in the UK. With a total generation capacity of 2,000MW it produces enough electricity to meet the needs of approximately 2 million people. In March 2008 WPL were contacted by E.On to enquire about a replacement sewage treatment solution to serve personnel located at the site's ...

  • Compost Site Comes Back From the Brink

    The largest composter in the state of Washington, Cedar Grove Compost Company in Seattle, had its hands full of challenges in 1997 — confronted with a half million dollar fine, a lawsuit, and angry neighbors. With the adoption of an Environmental Management System (EMS), the compost facility has turned its precarious situation around and stayed in business, while dramatically cutting odor ...

  • A Tale of Two Sites - Enhanced Bioremediation of Explosives Impacted Soils

    The problem with OE compounds in soil A variety of organic explosive (OE) compounds have been used for military, geological and industrial applications throughout North America, and in most industrialized nations. During their manufacture, formulation and storage, these compounds have migrated to the soil. Compounds such as 2,4,6-trinitrotoluene (TNT), hexahydro-1,3,5-trinitro-1,3,5-triazine ...


  • ON-SITE SEWAGE SYSTEMS: NEW OUTLOOK FOR DECENTRALIZED WASTEWATER TREATMENT

    As researchers analyze the soils’ ability to absorb discharge, more knowledge is gained about alternatives to septic tanks and standard drain fields that include peat filter systems, constructed wetlands and drip irrigation. ONE out of every four American households currently treat and release wastewater on their own property. Although most people assume that on-site systems are confined to rural ...


  • Site Vulnerability Assessments for Facilities That Use, Store, or Transport Chemicals

    In response to pressing issues facing the new Department of Homeland Security, over 15,000 chemical and industrial plants may have to evaluate their vulnerability to terrorist attack and improve countermeasures at their facilities. Federal lawmakers are considering two bills requiring facilities to submit site security plans: the Chemical Security Act (Senate Bill S. 157, reintroduced in January, ...

  • Solving waste oil management and removal problems in power generating plants

    If your plant is like most, it is doing a good job of preventing oily water waste and waste oils from escaping into the environment. But at what cost? As labor resources dwindle, operating and maintaining drainage systems, oil separators, and sometimes inadequate oil removal equipment is expensive. Paying higher than needed costs for waste oil disposal, filtration and water treatment due to these ...
