  • A preliminary review of gas-to-particle conversion monitoring and modelling efforts in the USA

    Ammonia and inorganic acid gases emitted from livestock and poultry operations, manure treatment, handling and application can affect air quality by the formation of secondary fine particles. The process of gas-to-particle conversion (GTPC) of relatively short-lived gaseous ammonia to more persistent fine particles can affect local and regional air quality far away from the agricultural sources. ...

  • Different technology options for monitoring oil in produced water – inline continuous monitoring and IR analysis

    No offshore facility wants to be caught with a sheen around their platform as that can result in a costly fine for exceeding discharge permit limits for oil. Onboard oil in water analyzers are necessary to ensure the oil/water separation systems are functioning properly before overboard disposal of the produced water. Bench top analyzers have traditionally been used to test oil in water although ...

  • Bioremediation Technologies for Marine Sediments

      USA – Baltic International Symposium on Advances in Marine Environmental Research, Monitoring and Technologies. Klaipeda, Lithuania. June 15-17, 2004 Global commerce relies heavily on waterborne transportation. Innovative, economical and environmentally sound ways to manage ...


  • Media expansion monitoring improves filtration

    In municipal surface water treatment plants, optimum filter performance is a crucial component. Filtration is the primary treatment process at water treatment plants, and backwashing is the primary means to keep filters functioning properly to produce safe drinking water for the public. Since 2000, Entech Design, Inc. has used underwater acoustic sensing technology to monitor filter media ...

  • Common Treatment Technologies for Nonhalogenated VOCs

    Soil vapor extraction (SVE), thermal desorption, and incineration are the presumptive remedies for Superfund sites with nonhalogenated VOC-contaminated soil. Because a presumptive remedy is a technology that EPA believes, based upon its past experience, generally will be the most appropriate remedy for a specified type of site, the presumptive remedy approach will accelerate site-specific ...

  • New laser-based dust emission monitoring system

    Abstract A new generation of continuous particulate matter concentration monitoring instruments is presented, covering a measuring range of 0 to 1000 mg/m3. The laser-based scattered light instrument gives an improved stability as well as excellent resolution in the low range. This enables high concentration measurement as well as especially low emission monitoring down to 0.01 mg/m3 with a ...

  • Monitoring Leaks from Heat Exchanger - Paper Plant

    The Situation A Paper plant in the Eastern US uses 500 GPM filtered pond water for cooling lubricating oil in their paper line.  The now warmer water is sewer to an on-site pond.  Because the water is used to cool lubricating oil, the plant could not reuse the water in their pulping process for fears of possible oil contamination of the paper pulp.  The plant needed to be ...

  • Reliable silica monitoring supports power station efficiency

    West Burton B CCGT is a Combined Cycle Gas Turbine power station near Nottingham in the UK. It has three open-cycle gas turbines capable of generating enough electricity for approximately 1.5 million UK homes. In common with all combustion based power stations, the CCGT has a requirement to monitor silica levels in the Plant’s water and steam processes. Sean Todd, the Plant’s Control ...

  • Application of Membrane Technology for the Recovery and Reuse of Water

    Abstract As water and sewer costs are expected to increase over the next decade, membrane technology will continue to be a viable and economical option in the recovery and reuse of water. This paper describes the mechanism of membrane effected separation (specifically reverse osmosis, ultrafiltration and microfiltration), membranes commercially available, membrane element configurations, and how ...


  • In situ Chemical Oxidation: An Innovative Groundwater Remediation Technology

    A promising new technology, in situ Chemical Oxidation (ISCO), has the potential to supplant the more widely used pump-and-treat groundwater remediation technology by destroying groundwater contamination in situ (in place). ISCO is the process of oxidizing contaminants in the groundwater and soil by injecting water containing high concentrations of an oxidant to the site of the contamination. ...

  • Monitoring heat exchanger leaks in Paper plant - Case Study

    The Situation A paper plant in the Eastern United States uses 500 gallons per minute filtered pond water for cooling lubricating oil in its paper line. The resulting warmed water is diverted to an onsite pond. Because the water is used to cool lubricating oil, the plant could not reuse the water in its pulping process for fears of possible oil contamination of ...

  • A novel acoustic imaging tool for monitoring the state of rapid sand filters

    A new technology based on acoustic waves is developed to monitor the state of sand filters used in drinking water treatment. Changes in the sand filter, due to the removal of suspended particles from the water and their accumulation in the pores, result in an increase of the bulk density and acoustic speed of the granular material. Consequently, the reflected acoustic response changes as the ...

  • Electrocoagulation Wastewater Treatment: Specialized Technology to meet the needs of food & beverage wastewater

    The effects of water scarcity and stricter environmental regulations placed on water usage are increasing the cost of using freshwater globally. The consequences of these increasing costs on food and beverage companies are twofold, since the companies are charged for both the water that they utilize in their processes and on their wastewater discharge. Additionally, the food and beverage industry ...

  • 2012 and Beyond: State of-the-Art Radiation Monitoring Systems for Nuclear Power Plants and Accelerators
