  • 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 ...

  • 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 ...

  • 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%, ...

  • 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 ...

  • Should you select bag or cartridge filters for your industrial application?

    When it comes to industrial filtration, there are several different filter types to choose from when working with industrial grade liquids, including both bag filters and cartridge filters. Ultimately, however, the ...

  • 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 ...

  • Advanced, High Efficiency and Absolute-Rated Polypropylene Depth Filters

    For manufacturers seeking greater dirt- holding capacity and longer service life, Shelco Filters announces the introduction of its new PDA and PDH Series Polypropylene Depth Filters. These filters were developed for critical applications requiring absolute (99.9%) or high retention (90%) efficiencies in an economical, melt-blown depth filter cartridge. Each cartridge is ...

  • High-flow Filtration will Benefit Everyone

    The availability of commercial-grade high-flow filters and housing systems offer exceptional benefits for manufacturers across all industries – particularly for RO pre-filtering, or for filtering water and wastewater. These large, pleated filters are better performing with an enormous filtration area – lowering cost (and frequency) of replacement filters, and reducing ...
