  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

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 media, frizzy balls ...

  • What water filtration system do I need?

    Water is abundantly available on the surface of the Earth. But do you know only 10% of the water is consumable, and the rest of the water is not usable? As the population is rapidly growing, the need for the consumable water is also growing. This increasing need for water has resulted in a scarcity of water in different regions. In such cases, the only solution is to reuse the ...
