  • High-Tech Filters

    The current economic situation of the cement industry creates sensitivity regarding off-times and process stability. More stringent air-pollution laws, especially when using waste-derived fuels, are drawing more attention to the off-gas cleaning facilities, usually bag filters. This article does not deal with electrostatic precipitators - as even they have well known disadvantages. By using more ...

  • Solid / gas separation with fabric filters

    A myriad of filter media are utilized today for separation of particulate matter in industrial gas filtration applications. These media range from single use (deposable) to semi-permanent media and include fiber, fabric, ceramic, membrane, metal mesh, and sintered metal media. Semi-permanent media are usually cleanable, either on or off-line, and are primarily intended for long-term (up to ...

    Maguin has developed the Cercat filter for high temperature air pollution control. In this article, David Gambier and Hélène Real outline the technology, as well as installations planned for 2009. Maguin has been present in the waste thermal treatment field since the 1970s. The company’s knowledge has been built through the turnkey supply of thermal treatment units for different kinds of products ...

  • To prevent blinding in dust collection systems, consider filter type, filter size and selection of the filter media used

    All dust collection systems, regardless of size, share a common problem—dust blinding. Simply stated, blinding is defined as when dust particles plug the holes in a filter and stop the flow of air through the filter, resulting in the dust collector performing poorly. All types of collectors, whether stand-alone units, cyclones or full-scale baghouses, are subject to blinding. To better ...

  • Treating Industrial Water with Membrane Technology

    A variety of industries are finding that it makes sense to reevaluate the way they treat industrial process water, both to improve the quality of their products and increase the efficiency of their processes. Purification systems utilizing crossflow membrane filtration, such as reverse osmosis (RO), nanofiltration (NF) or ultrafiltration (UF) can be a good alternative to traditional filtration ...


  • Crusher and milling machine in stone processing industry

    Stone processing mainly includes crushing and grinding. Both methods are used to reduce the size of or powder industrial rocks and minerals by crushers or grinding machines, which are called Stone processing machines and equipments. After processing, the stone or rock can apply in construction, building, highway and some chemical industries. Crusher is to make bigger stone (30mm~1000mm) smaller ...

  • 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, ...

  • Mercury spill control procedures - industrial hygiene news

    Mercury is a known neurotoxin that is extremely toxic even in small amounts. It directly affects the central nervous and renal systems, causing developmental delays, motor and brain problems like those associated with autism. Mercury’s hidden danger also lies in when at room temperature, when exposed it vaporizes readily. Once it has become an aerosol, it is absorbed into the lungs and ...


  • Controlling scale deposits in the pulp & paper industry

    The pulp and paper industry is one of the heaviest users of water within the North American industrial economy, requiring on average 54 cubic meters of water per metric ton of finished product.  As water is used in nearly every part of the manufacturing process, accumulation of scale is a phenomenon that can occur in all pulp and paper making processes. This occurs even with the purest water ...

  • Controlling Stack Emissions in the Wood Products Industry

    Electrostatic precipitation has been a reliable technology since the early 1900's. Originally developed to abate serious smoke nuisances, the manufacturers of zinc, copper, and lead quickly found electric gas cleaning a cost efficient way to recover valuable product carried out of the stacks from furnace operations. Today electrostatic precipitators are found mainly on large power plants, cement ...


  • Pilot and Industrial-Scale Experimental Investigation of Numerically Optimized Cyclones

    A new geometry of reverse-flow gas cyclones obtained by numerical optimization was shown at the laboratory scale to be significantly more efficient than other high-efficiency designs. However, it is usually recognized that experimental results obtained with laboratory-scale or sampling cyclones cannot be extrapolated to pilot or industrial scales. The present paper confirms, at these larger ...
