  • Filter backwash water treatment options

    Filtration acts as the final step in the removal of suspended matter and protozoa. The accumulated residue is removed during the backwash process and any subsequent recycling of filter backwash water could potentially re-introduce these contaminants into the main treatment process. By separating the filter backwash water from the main treatment process, factors that could interfere with the ...

  • Nitrogen removal in micro-polluted surface water by the combined process of bio-filter and ecological gravel bed

    Nitrogen removal in micro-polluted surface water by the combined process of a bio-filter and an ecological gravel bed was studied. Sodium acetate was added into micro-polluted surface water as carbon source and the nitrogen removal under different C/N ratio, hydraulic load and temperature were investigated. The results showed that the variations in C/N ratio, hydraulic load and temperature have ...

  • Organic matter removal in bio-filters to achieve biologically stable water downstream of the process

    Organic removal contaminants reclamation has increased over the past years as it has many advantages over other treatments. Product water from water treatment plants can be chemically complex resulting in physical and biological changes during transportation in the distribution systems. The general aim of this study was to evaluate the effectiveness of biofilters for reducing the concentration ...

  • Low cost processes for the removal of phosphates in water and wastewater

    This paper presents a synopsis of various low-cost techniques employed for the removal of phosphates from water and treated wastewater. Techniques employed include seawater flocculation and coagulation/flocculation using bittern, adsorption on fluidised raw dolomite bed, and filtration through iron and aluminium coated filter media. Seawater flocculation at a seawater concentration of 10% ...

  • Biofilm control strategies in industrial processing waters

    Bacterial biofilms cause a number of serious problems for industrial fluid processing operations. Mechanical blockages, impedance of heat transfer processes and microbially induced corrosion result in billions of dollars of losses each year. In engineered systems, such as cooling water systems, food processing, and other industrial applications possible risk to public health and product spoilage ...

  • Treatment of Spent Filter Backwash Wastewater Using Dissolved Air Flotation Process

    Spent Filter Backwash Water (SWW) is a major recycle stream that accounts for 10% (about 30 mgd) of the average flow at Blue Plains Advanced Wastewater Treatment Plant (AWTP) and a similar proportion of nitrification and denitrification treatment process capacity (DCWASA Focus, November 2004). The peak SWW flow and load result from increased filter washing during high flow events. The combined ...

  • Filter aids

    Filter aids are used to assist filtration of colloids, extra fine particles, gel like, and highly compactible materials, which are difficult to be filtered due to low filtrate rate, unacceptable filtrate clarity, high cake moisture content, or serious filter medium clogging. They can be used as “precoat” on the surface of filter media or in conjunction with feeding suspension as ...

  • Combination filters

    Simply defined, a combination filter is one that does at least one other processing job at the same time as filtering a suspension. The classic example, of course, is the packed bed of activated charcoal, which acts as a remover of chemical impurities from the suspension, as well as removing dust particles - although this is actually not a very good example, because it is primarily an adsorber, ...

  • Recycle of waste backwash water in ultrafiltration drinking water treatment processes

    In drinking water treatment, ultrafiltration (UF) membrane systems are generally operated at 90 to 95% recovery with production losses resulting from waste residual streams such as backwash water and clean-in-place (CIP) liquid residuals. In drought-prone regions, it may be desirable to apply alternative UF plant design configurations to increase recovery rates and minimize water loss. This ...

  • Soil Filters

    Soil filters (in german: Retentionsbodenfilter) are facilities for the removal of nutrients and/or pollutants; typically on the level of an industrial site, a quarter or a drainage system (sub-)catchment. Usually they are located at the discharge points to surface waterbodies to ensure water quality standards. Soil filters consist of two parts: The first part is a retention pond or basin for ...

  • An antimicrobial polycationic sand filter for water disinfection

    A new sand filtration water disinfection technology is developed which relies on the antimicrobial properties of hydrophobic polycations (N-hexylated polyethylenimine) covalently attached to the sand's surface. The efficacy of the filter disinfection process was evaluated both with water spiked with E. coli and with real aqueous effluent from a wastewater treatment plant. For the ...

  • Peach Processing Wastewater Treatment

    A major fresh pack operation of peaches and nectarines needed a screening system to remove the labels and peach fuzz from their wash water before it was pumped from the pond for irrigation use. Flow to the pond is a steady flow of 50 gpm, rising to 600 gpm during periodic draining of the peach coolers and washing systems. The water is a combination of wash water, labels and fuzz from the fruit, ...

  • Treatment of oil-field produced water by combined process of Anaerobic Baffled Reactor (ABR)-Biological Aerated Filter (BAF): a pilot study

    The combined process of Anaerobic Baffled Reactor (ABR) and Biological Aerated Filter (BAF) was used to treat the oil-field produced water. The experimental results showed that for ABR the removal efficiency of oil and COD was 84.5%, 40.8%, respectively, and the ratio of BOD5/COD of the effluent increased 24.8% when the flow rate was 0.3 m³/h. For the BAF, when the hydraulic loading rate was ...

  • Titanium Scrap Metal Processing

    Background A world-class processor of titanium scrap had a wash system whose cleaning solution was becoming contaminated with both free floating unemulsified tramp oil and emulsified water soluble oil that was being washed off of titanium turnings. As the level of oil contamination increased over time in the wash solution, cleaning effectiveness diminished. The processor uses a metric, ...
