  • Monitoring NH3, N2O, CO2 and CH4 emissions

    In France, as in other countries, there is a need to improve knowledge of greenhouse gas and ammonia emissions from livestock production with various management options. The aim of this study was to quantify the NH3, N2O, CO2 and CH4 emissions from two pig solid manure heaps, turned and not turned, in order to examine the effect of turning on gaseous emissions and to obtain additional information ...

  • Quality and first flush analysis of stormwater runoff from a tropical commercial catchment

    This paper examines the storm runoff quality from a commercial area in south Johor, Malaysia. Six storm events with a total of 68 storm runoff samples were analyzed. Event Mean Concentration (EMC) for all constituents analysed showed large inter-event variation. Site mean concentrations (SMC) for total suspended solids (TSS), oil and grease (O&G), biochemical oxygen demand (BOD), chemical oxygen ...

  • Is Your Moving Bed Biofilm Reactor (Mbbr) Running On All Cylinders?

    Evaluation of a full-scale MBBR process for nitrification is reported. Performance of the MBBR was found to be highly dependent on the hydraulic characteristics of the basin which could be optimized with improved influent flow distribution at the basin inlet. Installing a baffle on the influent pipe or introducing influent at multiple points located laterally across the entire influent end of the ...


  • Nitrogen removal and ammonia-oxidising bacteria in a vertical flow constructed wetland treating inorganic wastewater

    Nitrogen removal performance and the ammonia-oxidising bacterial (AOB) community were assessed in the batch loaded 1.3 ha saturated surface vertical flow wetland at CSBP Ltd, a fertiliser and chemical manufacturer located in Kwinana, Western Australia. From September 2008 to October 2009 water quality was monitored and sediment samples collected for bacterial analyses. During the period of study ...

  • Impacts of Novel Protein Foods on Sustainable Food Production and Consumption: Lifestyle Change and Environmental Policy

    We analyse the impacts of a change in consumers’ preference for Novel Protein Foods (NPFs), i.e. a lifestyle change with respect to meat consumption, and the impacts of environmental policies e.g. tradable emission permits for greenhouse gases (GHGs) or an EU ammonia (NH3) emission bound per hectare. For our analysis we use a global applied general equilibrium (AGE) model that includes consumers’ ...

  • Replacement of hazardous chromium impregnating agent from silver/copper/chromium-impregnated active carbon

    Activated carbon (AC) is widely used as an effective adsorbent in many applications, including industrial-scale air purification systems and air filter systems in gas masks. In general, ACs without chemical impregnation are good adsorbents of organic vapors but poor adsorbents of lowmolecular-weight or polar gases such as chlorine, sulfur dioxide (SO2), formaldehyde, and ammonia (NH3). ...

  • NEC Directive Status Report 2014

    Reporting by Member States under Directive 2001/81/EC of the European Parliament and of the Council of 23 October 2001 on national emission ceilings for certain atmospheric pollutants This report describes the most recent emission inventory information provided by the Member States of the European Union (EU) at the end of 2014, under Directive 2001/81/EC of the European Parliament and of the ...

  • NEC Directive status report 2011

    'The aim [of the National Emission Ceilings Directive] is to limit emissions of acidifying and eutrophying pollutants and ozone precursors in order to improve the protection in the Community of the environment and human health... by establishing national emission ceilings…' Directive 2001/81/EC, the National Emission Ceilings Directive (NECD) (EC, 2001) highlights the importance of ...

  • Enhancing Biological Nutrient Reduction in Advanced Individual Onsite Wastewater Treatment Systems

    ABSTRACTAdvanced onsite systems need to continue to improve wastewater treatment through nutrient reduction. Some advanced onsite systems have been shown to reduce nutrients significantly. However, with modifications, these systems can reduce total inorganic nitrogen (TIN) to an even greater degree, and nitrate to levels below federal drinkingwater standards. INTRODUCTIONNitrogen compounds in ...

  • Development of a Conceptual Model to Explain Apparent Free Ammonia Inhibition in Wastewater Systems

    ABSTRACTThe common consensus among researchers and practitioners alike is that high free ammonia concentrations cause nitrite oxidizer inhibition in wastewater treatment systems. The work of Anthonisen et al. (1976), who produced an operational chart providing guidance on the free ammonia concentrations most likely to produce nitrite oxidizer inhibition, is considered by many to be the definitive ...

  • FTIR becomes best option for multi-gas emissions

    Globally, the number of industrial processes and emissions being monitored with Gasmet’s FTIR multi-gas technology has increased enormously in recent years as process managers exploit the benefits of being able to monitor a wide range of gases simultaneously and with minimal maintenance and calibration requirements. Gasmet CEMS (continuous emissions monitoring systems) are used for ...

  • Air pollution in Europe 1990-2004

    Overall picture This report analyses and presents changes in air pollutant emissions and their possible health or ecosystem impacts in Europe covering the period 1990–2004. Emissions of all air pollutants fell substantially during the period 1990–2004 in the 32 EEA member countries (EEA-32), resulting in improved air quality over the region. However, ambient concentrations of particulate ...

  • Revealing the costs of air pollution from industrial facilities in Europe

    This European Environment Agency (EEA) report assesses the damage costs to health and the environment resulting from pollutants emitted from industrial facilities. It is based on the latest information, namely for 2009, publicly available through the European Pollutant Release and Transfer Register (E-PRTR, 2011) in line with the United Nations Economic Commission for Europe (UNECE) Aarhus ...

  • Wastewater Treatment Plant Monitors Greenhouse Gas Emissions

    Globally, little attention is paid to gaseous emissions from wastewater treatment processes. This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions of greenhouse gases (GHGs) to help in the city’s efforts to ...

  • Total solution: Gas and particulate analysis in Cement industry

    Cement plants are increasingly required to install continuous emission monitoring systems (CEMS). While these represent a significant financial outlay, a range of other factors also need to be considered when selecting a suitable CEMS. To the inexperienced, selecting a suitable CEM can mistakenly be considered as simply ensuring that the applicable national regulations (eg MACT in the USA, ...
