  • 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 ...

  • Engineered biofiltration for ultrafiltration fouling mitigation and disinfection by-product precursor control

    A pilot-scale study was conducted to evaluate the impact of several biofiltration enhancement strategies in terms of organic removal to reduce disinfection by-product (DBP) formation potential and mitigate ultrafiltration (UF) fouling. Strategies included nutrient addition (nitrogen and phosphorus) to optimize metabolic degradation of organics, use of hydrogen peroxide (H2O2, peroxide) ...

  • Biofiltration optimization: phosphorus supplementation effects on disinfection byproduct formation potential

    This study investigates the effects of phosphorus supplementation on the formation potential of total trihalomethanes (TTHMfp) and five species of haloacetic acids (HAA5fp) during exposure to clearwell disinfection contact times. In addition, the study investigates the effects of phosphorus supplementation on the dissolved oxygen, organic carbon and nitrogen removal along with biofilm ...

  • 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, ...

  • 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 ...

  • Water reuse for the bottled water industry

    ABSTRACTThe bottled water industry uses a machine specifically designed for the washing of its containers (19-L capacity) and generates 6-L wastewater/container. This effluent can be used for watering of green areas and car washing. The objectives of the present work were to characterize the effluent and to propose a specific treatment to enable reuse of the effluent from the container washing ...

  • A large‐scale field trial of thin‐layer capping of PCDD/F‐contaminated sediments: Sediment‐to‐water fluxes up to five years post‐amendment

    The longer‐term effect (3‐5 y) of thin‐layer capping on in situ sediment‐to‐surface water fluxes was monitored in a large‐scale field experiment in the polychlorinated dibenzodioxin and dibenzofuran (PCDD/F) contaminated Grenlandfjords, Norway (four trial plots of 10,000 to 40,000 m2 at 30 to 100 m water depth). Active caps (designed thickness 2.5 cm) were established in two fjords, consisting ...

  • 25 Years of Success – Outokumpu Stainless DC Plasma Smelting Facility

    Design is not just what is looks and feels like. Design is how it works. Between 1982 and 1987, British Steel (Outokumpu today) made extensive investigations into the treatment of steel dust. Their research was far and wide and covered off many various methods of recycling, including alternative to plasma technologies. But, in 1985, they engaged Tetronics International to carry out a ...

  • Victor Project – De Beers Canada, Ontario case study

    In early 2006 De Beers Canada began the construction of its first Ontario diamond mine, in the James Bay Lowlands. To provide drinking water for this mining camp and its daily workforce of nearly 1,000 , the engineering- consulting firm AMEC recommended that De Beers Canada call on the expertise of H2O Innovation. H2O presented a solution that matched its client's very special needs and ...

  • Sea water desalination for sagunto, Spain

    The Problem The Sagunto locality is situated in the region of the Camp of Morvedre in Spain. In recent years, a strong industrial growth has been anticipated in the zone. This has provoked a growing requirement for water in the Municipal Region of Sagunto. For this situation, the Sagunto Council planed to cover part of the future hydraulic deficit for short and long term with the ...

  • Using Nanofiltration in Beverage Production

    The following article is based on a paper presented in August, 1990 at the 21st Annual Meeting of the Fine Particle Society in San Diego. Soft drink manufacturers, not to mention manufacturers of other beverage products, have always had a keen interest in the water that goes into their products. After all, it is the water that typically makes up 80%-90% of the product. In the past the water has ...

  • Methods of Water Purification

    This article is excerpted from 'Pure Water Handbook' published by Osmonics®, Inc. of Minnetonka, Minnesota USA and is printed with permission of Osmonics, Inc. Water treatment can be defined as any procedure or method used to alter the chemical composition or natural 'behavior' of a water supply. Water supplies are classified as either surface water or groundwater. The majority of public or ...

  • Water Reuse Terminology

    All water on Earth is used and reused, over and over, in an elegant water cycle. Water reuse occurs in various ways on a daily basis. It happens when a community’s treated wastewater is discharged into rivers or other water bodies. If you live in a community downstream of another, chances are you are reusing water from an upstream town. Scientifically proven advances in water technology ...
