  • 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 ...

  • 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 ...

  • Advantages and basic facts for the use of Lenzing PROFILEN based filter media

    Normal PTFE filter bags have a very good chemical resistance but on the other hand they do not have a high dust separation efficiency. Lenzing PROFILEN® is a compromise between a high efficiency and a high flow rate after cleaning of gases with all the positive aspects of normal PTFE bags. Basics To acquire a better feeling and understanding for the advantages of Lenzing PROFILEN® it is necessary ...

  • Equivalence of Air and Water Permeability Tests in Evaluating Engineering Fabrics

    Permeability characteristics of civil engineering filter fabrics are currently evaluated by three types of tests: air permeability and falling-head and constant-head water permeability. Test procedures for the falling-head and constant-head water permeability tests are discussed, and results from these tests are correlated to air permeability results for filter fabrics. Several commercially ...

  • C&L Fabrication Select Warden Biomedia To Install New Wastewater Treatment Plant at Darver Castle - Case Study

    Based in County Louth on the east coast of Ireland, Darver Castle sits in 50 acres of fine parkland, and provides hotel and wedding facilities. The existing wastewater treatment plant at Darver Castle was experiencing challenges in operating at the level of consent limit set by the Environment Protection Agency (EPA). It was clear that the existing treatment plant needed to be replaced with a new ...

  • Attachment behaviour of inorganic particles on fibrous media: combined effects of dissolved organics and divalent cations

    A systematic study was carried out to investigate the attachment of inorganic particles to fabric media in the presence of divalent cations and the dissolved organics in water, on filter media, or on both. The presence of organics (humic acid, HA) reduced the attachment of inorganic particles on the fabric. Specific attachment trends were observed for the inorganic particles–fibre system. ...

  • Removing Solids with Automatic Self-Cleaning Filters

    Introduction The “art” of filtration utilizes many methods for separating solid particles from fluids. There is often no right or wrong method. Water quality and customer requirements usually determine the “best” method for each unique situation. Ridged screens, pleated cartridges, string wound cartridges, melt blown cartridges, woven fabrics, non woven fabrics, sintered metals, granular ...

  • Improve performance by installing a larger filter bag

    YOU MIGHT NOT NEED a more powerful dust collector after all. That’s the word from woodworkers who’ve replaced the original equipment filterbags on their collectors with bags that are more efficient. You might ask, “What can be more efficient than the 1 micron bag that came with my collector?” The answer is a 1 micron bag that’s properly sized for your machine and ...

  • Evaluation of dynamic membrane formation and filtration models at constant pressure in a combined coagulation/dynamic membrane process in treating polluted river water

    In this study, a dynamic membrane (DM) was formed by flocs produced by river water pollutants reacting with polyaluminum chloride (PAC). The DM was used to separate the flocs from the mixed liquor at constant pressure. Two support media for the DM were tested: non-woven fabric filter and dacron mesh. The formation time of the DM was determined according to the critical flux. The formation ...

  • Can we reposition the preferred geological conditions necessary for an infil

    The quantity and quality of feed water for desalting is critical for efficient operation of a desalination plant. This paper considers a synthetic permeable system designed to take advantages of the advances in directional drilling as well as incorporate the use of geotextile fabrics to transfer the preferred infiltration characteristics to any coastal site. The filtered seawater collection ...


  • Efficient Removal of Organic and Inorganic Suspended Solids

    ABSTRACT The Romans used sand as a filter media to treat their drinking water 2000 years ago. Centuries ago water was poured through layers of cloth to remove visible impurities in drinking water with fabric bags and paper cartridges soon following. Darcy employed sand beds in Dijon, France over 200 years ago to conduct his experiments for developing his famous equation to describe fluid flow ...

  • OM-1 Oil Mist Eliminators Collect Coolant Mists, Lubricant Mists, Smoke

    A major midwest metalworking facility uses 24 OM-1 Mist Eliminators to collect oil mists from over 200 sources, including grinding, dressing, CNC machining, lathes and heat treating operations.  OM-1's ability to accommodate smoke gives it an advantage over centrifugal-type oil mist collectors, which are not usable for smoke. Both soluble and non-soluble oils are used;  OM-1 collects ...
