  • Field demonstration of a near-real-time multi-metals ambient fence line monitor case study

    National emissions standards for hazardous air pollutants (HAPs) are required under Section 112 of the Clean Air Act to limit the release of specified HAPs. Permitting, monitoring and enforcement of these emission limits are an integral part of managing air quality to protect human health and the environment. However, this is difficult and highly uncertain in the case of fugitive emissions ...

  • Guide for developing a multi-metals, Fence-line monitoring plan for fugitive emissions using x-ray based Monitorsa case study

    Airborne metals and metal compounds are of particular concern to human health. Not only are they included in the United States (U.S.) Environmental Protection Agency’s (EPA) list of 187 hazardous air pollutants (HAPs), they represent 8 of the 33 urban pollutants identified by the EPA as posing the greatest potential health threat in urban areas. This is particularly significant since 80% of ...

  • Planning For Fenceline Monitoring

    The development of a general framework for fence-line monitoring can go a long way toward getting a plan quickly implemented, with less stress and potentially large cost-savings. Automation can greatly reduce operational costs of the fence-line monitoring as well as reducing data loss due to equipment problems. No facilty expects to do fence-line monitoring, therefore they seldom plan for it, but ...

  • Measuring unburned carbon in flyash with an automated, on-line monitor

    Increasingly stringent NOx regulations have required plant operators to modify traditional combustion processes. SOx regulations and deregulation have forced plant operators to diversify their coal sources. And new mercury control requirements have been instituted by the U.S. Environmental Protection Agency. These changes challenge plant operators who are trying to achieve the low carbon levels ...

  • On-line monitoring of enzymatic activities in water and water resources

    On-site detection of enzymatic activities has been suggested as a rapid surrogate for microbiological pollution monitoring of water resources (e.g. using glucuronidases, galactosidases, esterases). Due to the possible short measuring intervals enzymatic methods have high potential as near-real time water quality monitoring tools. This presentation describes the successful realization and ...

  • Nuclear power plant on-line sensor calibration monitoring implementation issues

    The use of empirical models for on-line monitoring (OLM) of safety-critical instrumentation for calibration reduction has been investigated for over a decade. To help support the regulatory review of possible licence amendments for US nuclear power plants, a series of three NUREG/CRs is being developed for the US Nuclear Regulatory Commission. The third of these volumes, entitled 'Limiting Case ...

  • Continuous on-line monitoring of dissolved oxygen in the activated sludge of a sewage treatment plant

    Dissolved oxygen is traditionally measured using a Clark cell, which relies upon a gas-permeable membrane for its opera-tion. Such sensors are subject to fouling with subsequent loss of accuracy, making frequent maintenance and calibration necessary. The objective of this development was to take advantage of specific properties of microelectrode arrays, such as low flow-dependence, insensitivity ...


  • Municipal sewer remote monitoring

    Sewers are critical heavy duty infrastructure components requiring costly maintenance. Many municipalities suffer from ageing pipelines that pose higher chances of failure. Sewer leak or overflow results in high cost as a result of civil reimbursement and due to inflected illness. Moreover Civilian frustration that results form the overflow is often targeted towards the municipality. Overflow can ...

  • Monitoring Hydrocarbons in Bilge Water

    The Situation Various processes onboard ships, such as machinery wash-down, maintenance, and leakage generate oily wastewater. This contaminated water flow collects in the bilge of the ship. Marine diesel, lubricating oils, grease, as well as garbage may be present in bilge water. The bilge water is discharged overboard, with oil and grease concentrations in the discharged water limited ...
