  • Developments in string wound filter cartridges

    String wound filter cartridges are the most commonly used filtration media for reducing contamination in water and other liquids. Filtration applications include reverse osmosis and water softening prefiltration, boiler feed water for steam generation, cooling towers and heat exchangers, bottled water, edible oils, oil and gas production, process water for textiles, electroplating and anodizing ...

  • 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 ...

  • Advances in String-Wound Sediment Filter Cartridges

    In the mid-1930s, the first string-wound depth filter cartridge entered the U.S. market. It was made from a woven wire mesh core surrounded by a cotton yarn, which was wound to form the depth filtration medium. The yarn itself was a tightly twisted medium and the major filtration essentially took place at the points of crossings of the yarns- which formed a diamond-shaped pat-tern-rather than ...

  • New polypropylene media for string-wound filter cartridges

    String-wound cartridges are among the most commonly used filtration media for reducing sediments and other suspended impurities in liquids and water. Traditionally these cartridges are made from 'roving' or 'friction-spun' yarn and factors such as media migration and chemical leaching were among the major drawbacks. With a new innovative development in the polypropylene filter media for making ...

  • The productive environmental laboratory: BSK Labs boosts efficiency with Metrohm IC

  • Unmixing Water From Waste: The imporance of filters, cartridges and housings as a function of manufacturing

    In manufacturing, water and water-based solutions are regularly filtered for various purposes and outcomes – including for cleaning, cooling, and movement. The filtering process is crucial to quality, performance, and cost savings. With the wrong filter in place, pumps can be destroyed, liquid being filtered can become “unusable” for the intended purpose, cleaning solvents can ...

  • New developments in filter cartridges for reverse osmosis pre-filtration

    Reverse osmosis (RO) pretreatment systems are designed to reduce suspended solids to a level that will provide the most suitable conditions for the performance of the membrane system. Depending upon the quality of the feed water, pretreatment may include settlement, clarification, multi-media filtration, and chemical treatment. However, sediment pre-filtration is always required to ensure that ...

  • Hom’: a simple point of use water treatment device

    This study sought to explore a locally assembled ‘Hom’ point of use water treatment device by assessing aspects of its performance and possible effects of using it on compliant households and communities. The conceptual framework highlights poverty and environmental degradation as causes and consequences of one another, with ill-health caused by water-borne diseases reinforcing both to form a ...

  • Let’s Talk About the Design of Cartridge Dust Collectors

    When it comes to choosing a cartridge filter, the choice usually depends on the application. Systems with finer particles require a cartridge filter, and these come in the choice of two. Surface and Depth-Type Filters A surface filteris ideal when filtering remains of similar-sized particles. Depth-type filters capture pollutants and particles ...

  • Continuous filament media revolutionize string wound cartridges

    Depth filter cartridges made from a cotton string wound media and a metal core were first introduced in the market in the mid-1930s. By the late 1970s cartridges with a polypropylene (PP) core and yarn had become popular because they had a very wide range of chemical resistance, and therefore could be used in a wide variety of applications. Initially, the string media was a roving (a bulky ...

  • 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 ...

  • Using a Self Bailer on Containment Sumps to Filter Hydrocarbons

    How do you eliminate problems associated with the collection of rainwater in outdoor containment systems and maintain compliance with EPA and Clean Water Act regulations?  Since most outdoor oil storage tank sumps and oil drum spill pallets will inevitably be exposed to local precipitation and storm water runoff from nearby catchment surfaces, it is necessary to make sure you ...

  • Continuous fibres lead to successfuI filter

    An improved design of wound string filter has doubled contaminant holding capacity and avoided the shedding of small fibres bad into the fluid. Tom Shelley investigates Wound string filters are setting new benchmarks for efficiently catching large amounts of dirt, without risk of introducing stray fibres or other contaminants into the fluid stream being filtered. Initially ...

  • 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 ...

  • Beta ratios explained and applied to liquid filter selection

    Liquid Filter Beta Ratios: Absolute rated liquid filter selection is tied to the media micron rating, materials of construction, construction design, and particulate removal efficiency filter factor known as its Beta Ratio (Figures 1, and 2). Consider that Engineering and Purchasing usually see absolute rated liquid filter efficiencies from vendor data sheets and quotes listed at 99%, ...

  • 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 ...
