  • 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 ...

  • Pilot Testing Microfilters and Cloth-Media Filters for Lake Augmentation

    ABSTRACTMicrofiltration and cloth-media filtration were pilot tested for plant expansion and water supply augmentation purposes. The performance of the pilot units was assessed by evaluating key influent and effluent data, including suspended solids, turbidity, total phosphorous, hydraulic loading rate, flux, and chemical addition. Results showed that one of the cloth-media filters, and both of ...

  • 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 ...

  • Performance Testing of Micro Media and Conventional Filters operating on Heavy Oil Produced Water in the San Joaquin Valley (California)

    "Performance Testing of Micro Media and Conventional Filters operating on Heavy Oil Produced Water in the San Joaquin Valley (California)", an application note, was presented by Michael Dejak and Michael Sheedy at the 23rd Annual Produced Water Society Seminar taking place in Houston, TX, this past January. The Produced Water Society Seminar is held every year. Each seminar emphasizes the latest ...

  • Manufacturing facility cleaning case study

    The Challenge A large Industrial manufacturing facility found that their process used to perform the necessary tasks was creating an undesirable accumulation of heavy metals dust throughout the entire plant. Not only was this a potential health risk to the plant workers, there was a structural and safety problem because the dust could spark and cause a fire or explosion. ...

  • Water filtration media: Talking about a revolution?

    Developments in any field of endeavour are nearly always evolutionary, not revolutionary. It is normal to expect advances in manufacturing equipment, process control and chemical science to facilitate product improvements. In the field of liquid filtration there is frustration at the seemingly unbreakable linkage that exists between increasing pressure drop and lower flow rates as gains are made ...

  • 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 ...

  • Side-by-Side Pilot Testing of Two Disk Filter Manufacturers at the City of Merced Wastewater Treatment Plant

    ABSTRACTAs more wastewater treatment facilities upgrade to tertiary treatment for pathogen removal and trace pollutant reduction, the options for tertiary filtration expand. The use of cloth-disk media filtration (disk filters) for tertiary filtration is becoming more common because of the effluent quality, lower backwash rates, small footprint, and ability to meet ...

  • (Let) electronic data media be shredded - Case Study

    When disposing of digital data media, it is advisable to take care, as untold amounts of confidential data are stored on our computers, USB sticks, CDs and DVDs etc. and represent a security risk, above all for trading companies. But what happens to these storage media at the end of their life? The Federal Office for Data Security makes an unequivocal recommendation that the rule for hard disks ...

  • High performance microbiological filter

    Filtration processes are a large cost component of pharmaceutical manufacture. The particle retention efficiency, particle capacity of the filter and the liquid flux all impact on product cost. A non woven electropositive filler media has been developed whose active component is an alumina (AlOOH) fiber two nanometers in diameter and having a surface area of 350-500 m7g. The nano fibers are ...
