  • Effective production of rapid filters with polystyrene granules as a media filter

    In conventional water treatment stations, the filter cleaning is performed with the use of filtered water. To save water and obtain higher production, the use of polystyrene (PS) beads has been proposed as a granular filter element because it is a granular element with a low specific mass. By being lightweight, this material requires a lower water velocity during backwash. The PS beads were ...

  • Biofiltration as pre-treatment to water harvesting and recycling

    This paper presents the results of the long term biofilter experiments conducted with raw stormwater collected from a canal at Carlton, in Sydney. Anthracite and granular activated carbon (GAC) were used as a single filter media in biofilter columns. Media heights of 75 and 40 cm were used. The filter columns were operated at filtration velocities of 0.12 and 0.25 m/h. The removal efficiency for ...

  • Rich microbial communities inhabit water treatment biofilters and are differentially affected by filter type and sampling depth

    Factors affecting microbial diversity (richness) and community structure in biofilter columns were investigated. At a pilot filtration plant, granular activated carbon (GAC), anthracite and sand-based filters were used to treat stormwater from an urban catchment. After 12 weeks operation, sand media filters clogged (hydraulic conductivity declining by 90%) and all filters were destructively ...

  • Dual-media filters, Fredrikstad waterworks, Norway

    Fredrikstad Waterworks in southeastern Norway has an annual water production of 15 mill. cubic metres and supplies the municipalities Fredrikstad and Hvaler. During autumn 2003 they have renovated their dual-media filters. After around 8 years of operation, the volume of filter media in the existing sand/anthracite-filters was significantly reduced resulting in poor filtering ...

  • Fouling of low-pressure membranes during drinking water treatment: effect of NOM components and biofiltration pretreatment

    Fouling is a major challenge for low-pressure membrane drinking water treatment systems. Previous research has demonstrated that under the right conditions, biofiltration is an effective method to reduce fouling of low-pressure polymeric membranes. This study provides additional insight into the effect of biofiltration as a pretreatment for fouling reduction by using river water with different ...

  • A Low Cost Solution to Reduce Total Nitrogen Discharged from WWTPs – Meeting the 3 mg/L Regulatory Limit in Total Nitrogen Using Existing Downflow Tertiary Media Filters as a Medium for Denitrification

    Existing tertiary media filters for solids removal may be used as a medium for denitrification of the secondary effluent to reduce the Total Nitrogen (TN) discharged by a Wastewater Treatment Plant (WWTP). This study explores the use of tertiary media filters as a low-cost solution for WWTPs in reducing TN levels to meet upcoming nutrient discharge regulations. Three pilotscale filters with sand ...

  • Benefits of Anthracite Carbon Media for Municipal Potable Water Treatment Applications?

    Treating water to be of potable water quality requires fairly considerable treatment based on initial water quality. Many tend to jump straight to thinking about more technologically advanced treatments like reverse osmosis and the similar. Of course, there is a bit more involved in drinking water treatment for municipalities. However, anthracite carbon media has been used extensively in ...

  • MBBR Helps Seafood manufacturer meet regulatory requirements

    Abstract Seafood processor in Manta Ecuador has a high strength wastewater with TSS as high as 20,000 mg/l, FOG 700 mg/l, COD of 13,000 mg/l and BOD of 6,000 mg/l. Wastewater is discharged into Pacific Ocean across the street from the factory. Current treatment plant produces effluent with TSS of 150 mg/l, FOG of 80 mg/l, COD of 800 mg/l and BOD of 400 mg/l on average. New laws require that ...

  • Hybrid filtration method for pre-treatment of stormwater

    In this study the hybrid filtration process (combining fibre filter with deep bed dual media filtration) was investigated as pre-treatment to stormwater. This process was investigated in-terms of reduction in turbidity, dissolved organic carbon (DOC), colour, headloss development across the filters, suspended solids removal, organic matter removal, nutrients and heavy matter (such as iron, ...

  • Case study - Filtralite Fredrikstad

    When renovating the filters the waterworks was interested in testing alternative filter media and replaced the anthracite layer in one of the filters with Filtralite® media for evaluation. Filtralite® is a filter media made of expanded clay and delivered by Saint-Gobain (Weber). In March 2002 Filtralite® media was installed on top of the existing sand in one out of totally 8 filters. ...

  • 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 ...

  • Evaluation of Ceralite-A as Ammonia Removal Biological Treatment Support Media - Case Study

    Project Description A novel biological oxidation filtration treatment process was evaluated for removal of ammonia from a California groundwater source. In addition to ammonia, this groundwater had other contaminants such as iron, manganese, methane, hydrogen sulfide odor, color, high organic carbon, etc. As such, more conventional treatment processes such as breakpoint chlorination ...
