  • Aerosol filtration in nanofiber filter media

    Nanofiber filter media are used in air filter applications where a compact filtration system with very high overall and fractional efficiency and low initial pressure drop  is required.  Moreover, because the aerodynamic drag force on nanofibers is very low compared to the drag on the large dust particles collected on the nanofiber media, this media is ideal for application to ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Filter Your Air with Cartridge Dust Collector

    A cartridge dust collector uses filtering cartridges and is a self-cleaning dust collector. The cartridges it uses are made from synthetic fibers and cellulose that is treated chemically. This ensures the particles are efficiently collected without forming an excessive pressure drop in the system. Structure A cartridge dust collector uses an air-jet cleaning structure to preserve ...

  • 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 ...

  • 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 ...

  • 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, ...

  • Why choose an electrostatic, washable air filter?

    When deciding what type of air conditioner or furnace filter to use, you should keep two things in mind: Airflow and Efficiency. In order to work at its optimum level, the a/c or heating unit requires no restriction to air flow. You should choose a filter that has the least effect on airflow, but removes the most dust from the air. ACI’s electrostatic air filters allow the air conditioning ...
