  • Particulate Control Strategies for Incineration

    Abstract This paper discusses various particulate emission control strategies that can be employed for Municipal Solid Waste (MSW), Municipal Sewage Sludge, and Industrial Waste Incineration facilities. An example will be given of a particulate control installation that successfully cleans off-gases from an incinerator at a large photographic products plant. Data supporting a theoretical ...


  • 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 ...

  • Why Your Project Should Include Articulated Concrete Blocks

    During any construction project, large or small, planning for potential construction erosion is essential. Failing to take into consideration the possibility of erosion when planning a construction site will not only reduce the quality of the soil at the site, but it may also damage surrounding properties, harm the local environment and result in hefty fines and liability costs. To avoid the ...

  • Wet Electrostatic Precipitation Demonstrating Promise for Fine Particulate Control

    Editor’s Note: Part l of this two-part feature on wet electrostatic precipitation (wet ESPs) outlines the need for multi-pollutant air pollution control technologies, the basics of wet and dry electrostatic precipitation, the ability of wet and dry ESPs to treat fine particulate, and the use of wet ESP technology at Northern States Power Company’s Sherco Station. Part II will explore the key ...


  • Predicting Diesel Particulate Filter Performance

    The diesel particulate filter (DPF) has been used for many years in the control of diesel particulate matter (DPM)emissions. This technology is characterised by extremely high efficiency and high sensitivity to the application conditions. Research and testing performed by Diesel Controls Ltd. over the past two years has resulted in improved methods for predicting the application based performance ...

  • 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 ...

  • 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, ...

  • Particulate matter, halogen and aerosols - Case Study

    Example: Production of anodes for aluminium smelters as well as electronic industry (TFT-LCD) Similar tasks: Carbon and graphite industry, smelting of aluminium, coating of metals An anode producer has several ring furnaces to stabilise the anodes by carbonization for later processing in a melting bath. The hot exhaust gases pass through double walls in between the anodes where the gases ...

  • Mesoscale controls on particulate matter pollution for a mega city in a semi-arid mountainous environment: Tehran, Iran

    Tehran, the mega-city capital of Iran, suffers from high concentrations of PM10 throughout the year. Emissions from transport combined with mesoscale atmospheric features related to the mountainous terrain lead to a distinctive diurnal pattern in concentrations. Air quality data from monitoring stations show that the highest concentrations of PM10 are in the morning and evening periods, ...

  • High efficient cyclone systems with electrostatic recirculation for particulate matter (PM) emission control

    The development of new optimized dedusting systems has particular and increasing relevance for atmospheric particulate emission control. Indeed, traditional "particulatetraps" present several disadvantages that foster the search for alternative solutions. Industrial cyclones are, for their robust construction, absence of moving parts and general application, an appropriate technology for emission ...

  • Influence of aeration and permeate flux on deposition of particulates on membrane surface

    In microfiltration, a deposit of foulant tends to form on the membrane surface and this usually controls the performance of the filtration process. This paper discusses the influence of physical parameters such as aeration and permeates flux on migration and deposition of above micron particles on the membrane surface. Kaolin clay suspension of particle 3.7–8▒μm with mean particle diameter 4.1▒μm ...
