    Summer 2015 marked the completion of two years successful operation of an ERG (Air Pollution Control) Ltd designed, installed and commissioned waste gas treatment plant at the Saffil production facility in Widnes.  Background Saffil Ltd, a wholly owned subsidiary of Unifrax, produces high temperature insulation products, for use in automotive catalytic convertors and other ...

  • Particulate polycyclic aromatic hydrocarbons in urban air of Tehran

    Epidemiological studies have shown correlations between the concentration of particles in the air and increase of daily rates of respiratory and cardiovascular diseases and mortality (Douglas et al.,1992; Jonathan et al.,1995; Auron et al.,1995). Elevated lung cancer rates among women in rural china have been attributed to emissions from their coal-fired stoves (Mumford et al.,1987;Alder and ...

  • Trends of lead in suspended particulate matter in Zagreb air

    Monitoring of lead in Total Suspended Particulate Matter (TSPM) started in Zagreb, Croatia in 1971 at three measuring sites. Monitoring of lead concentrations in PM10 started in 1999. This paper presents the trends of annual mean values for lead concentrations in TSPM and in PM10 particles. The obtained data showed a decreasing trend of lead in TSPM, especially during the last ten years when the ...

  • Air/water cleaning for the control of particulate fouling

    Fouling of feed spacers in spiral wound membrane elements due to particulate fouling and biofouling is one of the main operational problems of nanofiltration or reverse osmosis membrane plants. Removal of particulate fouling from spiral wound membrane elements is investigated using frequent air/water cleaning (AWC). In a pilot setup two spiral wound elements were operated in parallel and were fed ...

  • Particulate removal - Case Study

    Application QAFCO (the Qatar Fertiliser Company) operates the world's largest ammonia and urea production site at Mesaieed City, Qatar. The QAFCO 5 expansion project is a $3.2 billion investment to expand capacity to help meet the increased demand from agriculture. It is scheduled to come on stream in 2011. Each of the QAFCO plants uses highly explosive high-pressure natural gas from ...

  • Expect Tighter Particulate Matter Standards

    Particulate matter (PM) is a hot button issue poised to raise business costs and litigation. The U.S. Environmental Protection Agency (EPA) was recently due to issue final PM standard revisions. EPA last year proposed stronger National Ambient Air Quality Standards (NAAQSs) for fine PM (2.5 micrometers or less in diameter (PM2.5)) and the 24-hour PM2.5 standard. However, EPA sought to keep annual ...

  • Case study - Organic particulate filtration

    Overview A food products company that mixes various types of waxes and other components to make the base for chewing gums was faced with the issue of cleaning up a slightly odorous, visible emission being exhausted from two of their process lines. The components of the emission were hot particles of chewing gum and some volatile organic compounds (VOC's). The particles would quickly clog ...

  • Seasonal apportionment of the sources of ambient air particulates in the city of Trieste

    A PCA/APCS model was applied to PM2.5 data, which were collected for the Svevo and Muggia districts of the City of Trieste. The sampling campaigns covered the winter and summer periods of 2006. The set of investigated species comprised major inorganic ions, organic and elemental carbon and several Polyaromatic Hydrocarbons (PAHs) that were considered as probable or possible carcinogens by ...

  • Health Effects of Fine Particulate Air Pollution: Lines that Connect

    Efforts to understand and mitigate the health effects of particulate matter (PM) air pollution have a rich and interesting history. This review focuses on six substantial lines of research that have been pursued since 1997 that have helped elucidate our understanding about the effects of PM on human health. There has been substantial progress in the evaluation of PM health effects at different ...

  • A Special Issue of the Journal of the Air & Waste Management Association on the Particulate Matter Supersites

    This special issue of the Journal of the Air & Waste Management Association contains 15 peer-reviewed scientific papers from the specialty conference Particulate Matter Supersites Program and Related Studies, which was held in February 2005 in Atlanta, GA. Other peer-reviewed papers will appear in companion issues of the Journal of Geophysical Research, Aerosol Science and Technology, and ...

  • Frequency distribution of particulate matter (PM10) in urban environments

    Hourly measurements of particulate matter with an aerodynamic diameter less than 10 µm (PM10) were recorded in Athens, Greece and Manchester, UK, for a period of one year. The lognormal, gamma and Weibull distributions were selected to fit the concentration frequency distribution of the measured PM10 data. Moreover, the statistics of Mean Bias Error (MBE), Root Mean Square Error (RMSE) and index ...

  • 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, ...
