  • Modeling of air stripping from volatile organic compounds in biological treatment processes

    The removal of volatile organic compounds from biological treatment processes occurs through several mechanisms. These include biodegradation, adsorption onto solids, and air stripping or volatilization to the atmosphere. Volatilization results in fugitive emissions to the atmosphere, which is largely uncontrolled. Recent regulations have called ...

  • Potential of biofiltration for VOCs emission control and safety aspects

    Directive 99/13/EC on the emission of Volatile Organic Compounds (VOCs) is impacting on several industries in Italy, as well in other EU countries. Many small enterprises have to invest in new control systems and need to be helped to choose an appropriate and safe technology. As VOCs are highly flammable compounds, high concentrations in emission flows can pose a fire and explosion hazard if ...

  • Biotreatment of Organic and Inorganic Odors

    Air emissions from manufacturing operations and waste treatment plants often consist of a combination of odors and volatile chemicals. Odors are inorganic or organic compounds, which are present in low concentrations, typically 20 ppmv or less, which have an unpleasant odor. Volatile chemicals are often present at higher concentrations than odors, but may or may not have any odors associated with ...

  • Methods for the control of oil vapour emissions

    There are many oil vapours to discharge from oil containers into the atmosphere in oil operations (such as storage and loading). Two basic concepts are discussed regarding the control of oil vapour emission (OVE). The first is to invent active methods to restrain the OVE. The second is to develop passive tail–end remediation technologies to control the released vapour. Oil vapour recovery ...

  • Investigation of the effects of temperature and sludge characteristics on odors and VOC emissions during the drying process of sewage sludge

    Sludge drying is a necessary step for sludge disposal. In this study, sludge was collected from two wastewater treatment plants, and dried at different temperatures in the laboratory. The emission of odor and total volatile organic compounds (TVOCs) during the sludge drying process were determined by an online odor monitoring system. The volatile organic compounds (VOCs) in off-gas were analyzed ...

  • Role of final cover soil in regulating volatile organic compounds: emissions from solid waste disposal sites in developing countries

    The objective of this study was to investigate the emission of Volatile Organic Compounds (VOCs) from solid waste disposal sites and their remediation at final cover soil. This research was conducted using field cover soil lysimeters placed at the surface of a solid waste dumping area and batch experiments in the laboratory. It was found that benzene, toluene, chloroform and perchloroethylene ...

  • Vertical distribution of VOCs and ozone observed in suburban North Carolina

    As a continuing effort by the State of North Carolina to develop a State Implementation Plan for ozone control in the Raleigh Metropolitan Statistical Area, vertical measurements of C2–C10 hydrocarbons and ozone are made on a 610 meter multi-communications tower. Results signify that both long-range transport from fossil fuel combustion, petroleum exploration, ...

  • Three-dimensional modelling of photochemical air pollution in Switzerland and comparison with a multi-parcel Lagrangian model

    The photochemical smog situation in Switzerland on 29 July, 1993 was simulated using the 3-D grid model UAM (Urban Airshed Model) and the results were compared with those of a multi-parcel Lagrangian model. Sensitivity analyses concerning initial conditions, emissions, deposition, biogenic volatile organic compounds (VOC), and emission reductions were carried out. Results were compared with field ...

  • Odour control with Direct Cold Plasma

    Odour emission during the production or processing of food and feed is often an unwelcome side effect. However, by using cold plasma technology, the smell can be reduced up to 95%. Increasingly, feed manufacturers are being required to address the issue of emitting of odour and harmful contaminants into the surrounding community. Local communities, special interest groups and government ...

  • Solvent Recovery South of the Border

    With the advent of NAFTA, Mexico's package-printing industry, a major source of VOC emissions, is under increasing pressure to comply with envronmental regulations. One company, Grafo Regia, pursued an air pollution control process that has an economic payback compared to traditional oxidation. Volatile organic compounds (VOC’s) find wide spread use in the gravure printing and flexible package ...
