  • Increased water treatment plant capacity at a Mexican power station using Micro Media Filters ahead of RO and Replacing EDI with ion exchange

    Abstract: This paper describes the process and equipment used to treat a Mexican secondary water source in order to supply boiler feed make-up to a combined cycle power plant. RO pretreatment is provided by a highly efficient micro media filter that produces a filtrate with a turbidity of 0.1 – 0.2 NTU and an SDI value of 3 – 5. Following the RO, a compressed-bed ion exchange system ...

  • 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 ...

  • Filter backwashing

    Backwashng a drinking water system filter means reversing and increasing the water's flow to flush out accumulated debris and particles. Backwashing is not only vital to the life of a filter, it is fundamental to the quality of water coming out of the filter. Sooner or later, all filters need to be backwashed or ...

  • RP18 as a Filter case study

    More than just an adsorbent fabric, RP18's special design qualities make it a good filter too. The construction of RP18 is such that there is a large amount of free space which allows water to pass through whilst retaining the oil. This has been illustrated also in 'A method for Cleaning Foreshores' case study. This fabric is useful where water flows are high and the amount of oil retained is ...

  • Replacement Fill Control Valves with Electronic Flow and Metering Improve Pressure, Stop Leakage and Prevent Valve Failures

    The City of Modesto, California is situated 90 miles east of San Francisco and has approximately 200,000 residents relying on 200,000 of gallons of water a day. The City needed to upgrade three water storage tanks that hold approximately 750,000 gallons each. After years of using motor operated valves to fill water storage tanks, the city recognized that there were just too many problems. ...

  • TB 72: Chinese chemical plant optimizes water treatment by replacing double pass ro with a single pass ro and liqui-cel® contactor system

    Electrodeionization (EDI) is widely used in many industrial water treatment systems throughout the world. In order to maximize the operating stability and life expectancy of an EDI system they were often designed with double pass RO using caustic injection pretreatment. However, in response to recent efforts to lower the capital expenditure and operating costs of double pass RO water treatment ...

  • Developments in string wound filter cartridges

    String wound filter cartridges are the most commonly used filtration media for reducing contamination in water and other liquids. Filtration applications include reverse osmosis and water softening prefiltration, boiler feed water for steam generation, cooling towers and heat exchangers, bottled water, edible oils, oil and gas production, process water for textiles, electroplating and anodizing ...

  • New Style Automatic Self-Cleaning Filters for Mill Cooling Water (Phase 1)

    ABSTRACT Replacement of hot-mill rolls is expensive and often requires production to cease during the process. Surface deterioration of rolls escalates as cooling water quality decreases. This manuscript will describe the installation and performance of a new cooling water filtration system in a northeast Ohio hot-roll mill that incorporates well proven suction scanning technology with ...

  • 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 ...

  • Dual-media filters, Fredrikstad waterworks, Norway
