  • Common Treatment Technologies for Halogenated VOCs in Air Emissions/ Off-Gases

    Three technologies that are most commonly used to treat halogenated VOCs in air emissions/off-gases are carbon adsorption, catalytic oxidation, and thermal oxidation. Carbon adsorption is a remediation technology in which pollutants are removed from air by physical adsorption onto the carbon grain. Carbon is 'activated' for this purpose by processing the carbon to create porous particles with a ...

  • How to Save with Cooling Tower Credits

    Cooling towers dissipate heat from recirculating water used to cool chillers, air conditioners, or other process equipment to the ambient air. Heat is rejected to the environment from cooling towers through the process of evaporation. Therefore, by design, cooling towers use significant amounts of water. The thermal efficiency and longevity of the cooling tower and equipment depend on the proper ...

  • Advanced Enviro - Septic™ Wastewater Treatment System Septic Tank Effluent Filters and Charco al (Odor) Filters NOT Recommended

    Abstract: Effluent filters are installed in the outlet from the septic tank with the intended purpose of retaining solids inside the tank, preventing them from entering the treatment system and/or dispersal field. The concern is that if solids escape from the septic tank, they could cause clogging of the system components or the soil interface. While this may be a legitimate concern for some ...

  • EPA mandatory reporting of GHGs rule

    Recent EPA Guidance EPA does not intend for the calibration requirements of 98.3(i) to apply to any units where the rule allows the use of “company records” to quantify fuel usage or other parameters; however, a facility’s GHG monitoring plan must include descriptions of the procedures and methods used for quality assurance, maintenance, repair of all flow meters ...

  • Workers` silica exposure at Fracking sites far exceeds OSHA Limit, NIOSH study finds

    The concentration of silica in the air workers breathe exceeded occupational health criteria at all 11 hydraulic fracturing sites tested by the National Institute for Occupational Safety and Health, the American Industrial Hygiene Association announced July 31. Researchers measured the silica levels of more than 100 personal breathing zone samples at fracking sites in five states, finding levels ...

  • Preparing for CRC – what should organisations be doing now?

    What is the CRC? The forthcoming Carbon Reduction Commitment (CRC), scheduled to start in April 2010, will be the first ‘cap and trade’ scheme aimed at reducing greenhouse gas emissions from non-energy intensive industries. Unlike previous emissions trading schemes, the CRC aims to encourage reductions in electricity use rather than directly limiting emissions from burning fossil fuels. ...

  • Project profile - Lummi Island, Washington arsenic, iron, sulfide treatment system

    Background In mid 2004, AdEdge Technologies Inc. (AdEdge) was selected by Miller Water Association and Anvil Corporation to assist in the design of a fullscale arsenic treatment project for this small community. Arsenic levels are alarmingly high at 0.18 mg/l, 18 times higher than the new Federal standard of 0.010 mg/l. In addition to arsenic, many of the homeowners using the water ...

  • Ambient Air Sampling Methods

    Pollutants are nothing but any substance that may present in an atmosphere in such a concentration that it may harmful to surrounding, living organism or human being. Sampling and analysis of air pollutants is known as Air quality monitoring and it is major part of environmental monitoring. There are many advanced types of ambient air Sampling methods. we will learn here only which are most ...

  • Legal lookout: meet the GHG rule

    EPA signs final rule requiring greenhouse gas emissions reporting. On Oct. 30, 2009, EPA issued a final rule that requires reporting of greenhouse gas (GHG) emissions from all sectors of the economy. The final rule applies to fossil fuel suppliers and industrial gas suppliers, direct GHG emitters, and manufacturers of heavy-duty and off-road vehicles and engines. The rule requires only that ...

  • Dry Ice –Carbon Dioxide: Where is it being used and how to handle safely?

    Carbon dioxide, in its solid form, is colder than ice.  It is so cold, in fact, that handling it without protection can cause frostbite.  It does not melt, but instead dissipates into a gas that can be dangerous to breathe.  This substance is called dry ice, and, when handled properly, has many useful applications. The most practical use of dry ice is to keep things cold. It can be ...

  • Hole Dug, Leak Found - City Of Ottawa Entrusts Smartball Platform To Look For Leaks In Tranmsission Main

    When your inspection task is to survey a critical pipeline for leaks, nothing is more satisfying than trusting your technology to predict the leak location and then standing by as the client excavates the area to find a flow of water within one meter of exactly where you said it would be. The above-described "leak-where-predicted" recently happened with the City of ...

  • Case study - Reactor vent emission control

    OVERVIEW Many chemical and petroleum companies use batch reactors to make their products.  These reactors typically have vents which are opened and closed during emptying, filling, mixing, heating or cooling and other steps of the production process.  The gases coming from these vents must be controlled under most government regulations.  Generally speaking, the ...
