  • 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 ...

  • MEDIA FILTRATION, MEMBRANES, OZONE, AND UV

    ABSTRACT For reclaimed water disinfection, pathogen reduction to acceptable public health risk levels is theprimary objective. A second emerging objective is the ability to destroy trace pollutants(endocrine disrupters (EDCs), pharmaceutically active compounds (PhACs)) at a reasonably lowcost.The WateReuse Foundation’s Innovative Reclaimed Water Treatment Project ...

  • Understanding the 3 Types of Arsenic Removal Used for Wastewater

    With the onset of the Industrial Revolution and the development of internal combustion engines and new manufacturing technologies, fresh water became an essential raw material not only for production, but for cooling purposes in manufacturing processes. However, when fresh water is used in an industrial process, it creates industrial wastewater composed of a variety of chemicals and other raw ...

  • Hydraulics stability of compost-based filtration media

    The longevity of compost-based storm water filtration systems has not been widely studied. Hydraulic conductivity measurements of compost amended sand media (20% and 50% v/v) within columns were undertaken. The results show that the filtration media in both columns had a reduction in the total saturated hydraulic conductivity. A tracer test showed there was no blockage due to biological or ...

  • Micro Media Filtration Proving Effective in Produced Water Softening Systems

    Having an eff ective, durable pretreatment system in advance of ion exchange produced-water softening systems is the fi rst, most critical line of defense – ensuring smooth, more troublefree performance downstream. It’s especially true when dealing with today’s ion exchange technologies, which require TSS (total suspended solids) of 0.1-0.5 mg/L and turbidities of 0.1-1 NTU ...

  • Power Industry using Micro-Media Filtration and short-bed ion exchange

    With the demand or higher efficiencies, lower maintenance and operating costs for boilwers and turbines, high-purity water treatment systems are becoming more crucial to the operation of power plants. Modern power plants, operating at supercritical and ultra upercritical boiler pressures and temperatures, require high-purity water that approaches quality levels at the theoretical levels. ...

  • Fox Metro Water Reclamation District Solves Filtration Problems with Innovative Aquadiamond® Cloth Media Filter

    The Fox Metro Water Reclamation District evaluated, installed, and successfully tested cloth media filtration in a diamond configuration in existing traveling bridge sand filter tanks. The conversion to the cloth media diamond filters increased the flow capacity of three existing sand filters basins from 79,485 m3/day (21 MGD) to 272,520 m3/day (72 MGD). The diamond filter builds on cloth media ...

  • Chemical and microstructural analyses for heavy metals removal from water media by ceramic membrane filtration

    This study aims to investigate the ability of low cost ceramic membrane filtration in removing three common heavy metals namely; Pb2+, Cu2+, and Cd2+ from water media. The work includes manufacturing ceramic membranes with dimensions of 15 by 15 cm and 2 cm thickness. The membranes were made from low cost materials of local clay mixed with different sawdust percentages of ...

  • Application of light-weight filtration media in an anoxic biofilter for nitrate removal from micro-polluted surface water

    The research investigated nitrate removal from micro-polluted surface water by the single-stage process of anoxic biofilter using light-weight polystyrene beads as filtration media. In this study, sodium acetate was used as an external carbon source and the nitrate removal efficiency under different regimes of hydraulic loading rate (HLR), water temperature, and C/N ratio was studied. In ...

  • A Comparison of Two Media Filtration BMP Treatments for the Removal of PAHS and Phthalates from Roadway Runoff

    Urban runoff is a major contributor to the degradation of our urban streams, rivers, and lakes (Pitt, 1995). Organic pollutants, such as PAHs and phthalates, in urban stormwater can contribute to receiving water degradation (EPA, 1983). A study in Rhode Island’s Narragansett Bay watershed found that urban runoff accounted for 71 percent of the total inputs to the bay for higher molecular weight ...


  • Filtration and manganese removal

    Manganese removal through a filter bed is generally carried out and accepted by practitioners and researchers as occurring through catalytic oxidation at the surface of MnO2 coated media, although manganese passage through a coated media filter has been little investigated.
