  • Filtration media: Shapes and manufacturing processes

    The shape of the filtration media and the production process directly affect the absorption capacity of the granulate and consequently the efficiency of filtration. Granules in the shape of a pellet (cylinder) do not facilitate such a high degree of compaction as spherical granules, so that the passage of the air flow becomes easier, ...

  • Technical Resources for Gas-Phase Air Filtration

    Gas-phase air filtration is a highly specialized branch of air filtration with a very short list of reputable and knowledgeable companies manufacturing the dry-scrubbing media, filters, and systems in which they are employed. The list becomes even shorter when considering where to go for the ...

  • Calculating pressure drop of nanofiber air filter media

    Nanofibers are becoming an integral part of many advanced air filtration media thanks to their enormous specific surface area. The large surface area, however, can cause strong resistance against fluid motion, which leads to an increase in pressure drop. Pressure drop caused by fibrous media has been the focus of many pioneering studies in the past, resulting in analytical or empirical ...

  • Pleatable UPE membrane media in pulse-cleaned dust removal air applications

    Media Selection For initial tests, three media were selected for comparison. These structures are all designed for use in pulse-cleanable cartridges, with processing on blade pleaters. Arioso™ M7001-11 is a Solupor® ultra-high molecular weight polyethylene (UPE) membrane designed for F9/MERV16 efficiency at very low resistance laminated to a 200 gsm, stiff, high permeability ...

  • World’s largest compressible media filtration plant eliminates combined sewer overflows, with potential for dry-weather use

    The City of Springfield, Ohio, recently opened its 100 MGD enhanced high-rate treatment facility, designed to treat and disinfect combined high-volume stormwater and wastewater flows generated by wet-weather conditions. Utilizing EPA-documented Compressible Media Filtration technology – FlexFilter™ from WesTech – the system can also provide tertiary filtration and disinfection ...

  • Gas-phase air filtration: Protecting you from what you can’t see.

    Air filtration, covered previously, targets solid matter (particulates) such as dirt, dust, leaves, and any visible airborne debris. Gas-phase filtration is for the unseen pollution that is airborne gases that may have an odor–but not always. This is chemistry that came from a liquid or solid to become a gas at ambient temperature. Gases act very differently than particles since they are ...

  • Innovative Multi-Media Filter – Continuous Backwash Filter

    The disadvantages of conventional MMF based pretreatment Conventional pretreatment is based on multimedia filters (MMF) implemented in large scale desalination plants. Although this filtration method is well proven and provides reliable filtration efficiency, it conceals an inherent drawback, the disadvantages of which relate mainly to the backwashing mechanism. The ...

  • It’s Time to Rethink Cooling Tower Filtration

    ABSTRACTThe dissipation of ambient or process heat in large HVAC systems, manufacturing facilities, power generation plants, refineries, metal mills and forges, chemical plants and food processors is most often accomplished by cooling towers. These simple structures facilitate the transfer of unwanted energy (heat) from a transport liquid (usually water) to the atmosphere. The bane of cooling ...

  • Rolled Filters Move Filtration in a New Direction

    When selecting filtration technology, industrial users have long wrestled with the tradeoffs of dirt-holding capacity versus particle selectivity or quick-and-dirty change-outs versus process time. For many applications, a self-contained rolled filter offers an effective solution to both problems. Constructed with polypropylene hardware and various media in a spiral-wound design, rolled filters ...

  • Application Data for Dry-Scrubbing Media in Collection Systems

    Abstract Dry-scrubbing systems have been used for many years to control odors in wastewater applications. The systems have ranged in size from larger multiple bed scrubbers for force mains and large pump station applications to smaller single bed systems and modular systems in small wet wells, motor control centers, and other areas. Two reasons for their continued use are simplicity of ...

  • The Dangers of Hydrogen Sulfide and Filtration with Activated Carbon

    Hydrogen sulfide (H2S) is a poisonous, highly flammable, colorless gas that is associated with a ‘rotten egg’ odor. As stated by cchealth.org, “hydrogen sulfide is created naturally by decaying organic matter and is released from sewage sludge, liquid manure, and sulfur hot springs.” It also is a by-product from industrial processes such as natural gas processing, ...

  • Expanding Reservoir Air Filters

    In all vented tanks, the rise and fall of fluid levels is offset by a corresponding volume of incoming and outgoing air. Keeping the incoming replacement air clean is essential for contamination control and thus the reliability of hydraulic systems. While targeting the system's reliability, JLM Systems Limited has developed the OilMiser™ Reservoir Aspirator (ORA) kit. This product represents a ...

  • Effective production of rapid filters with polystyrene granules as a media filter

    In conventional water treatment stations, the filter cleaning is performed with the use of filtered water. To save water and obtain higher production, the use of polystyrene (PS) beads has been proposed as a granular filter element because it is a granular element with a low specific mass. By being lightweight, this material requires a lower water velocity during backwash. The PS beads were ...
