  • Solid / gas separation with fabric filters

    A myriad of filter media are utilized today for separation of particulate matter in industrial gas filtration applications. These media range from single use (deposable) to semi-permanent media and include fiber, fabric, ceramic, membrane, metal mesh, and sintered metal media. Semi-permanent media are usually cleanable, either on or off-line, and are primarily intended for long-term (up to ...

  • Two Case Histories of Industrial Water Reuse Via Membrane Technology

    Abstract This paper describes two successful applications of ultrafiltration (UF) and reverse osmosis (RO) membrane technology used to reclaim water, reduce waste water discharge costs. The first case history covers oily waste water treatment at a major aluminum beverage can manufacturing plant. The second case describes treatment of waste water from a multi-plating bath section of a major ...


  • Biological filtration of poor quality brackish water reducing Reverse Osmosis membrane fouling

    Abstract A primary limitation in applying Reverse Osmosis (RO) is loss of performance caused by membrane fouling resulting from compounds that bacteria can use as energy or nutrient sources. When these compounds enter RO membranes, they are capable of sustaining extensive bacterial growths on the membrane sheets as well as within feed channel spacers. This leads to the entrapment of ...

  • New developments in filter cartridges for reverse osmosis pre-filtration

    Reverse osmosis (RO) pretreatment systems are designed to reduce suspended solids to a level that will provide the most suitable conditions for the performance of the membrane system. Depending upon the quality of the feed water, pretreatment may include settlement, clarification, multi-media filtration, and chemical treatment. However, sediment pre-filtration is always required to ensure that ...

  • BioLargo`s AOS Filter Wins `Technology Star Award` - New Technology Magazine -The First Word on Oil Patch Innovation

    Advanced disinfectant technology developer sets sights on oil and gas applications A small publicly-listed Santa Ana, Calif.–based company that is developing water purification and advanced disinfectant technologies, all using some form of iodine, sees one of its Edmonton-developed technologies as a way to clean up and even eliminate oilsands mining tailings ...

  • Understanding Crossflow Filtration

    There's a lot of attention being given to water availability and purity, with good reason. Obtaining enough water is a struggle in some areas. In others, water is tainted with contaminants. It is therefore predictable that regulations and economics will force careful water treatment and stress water re-use. Fortunately, there are water treatment methods that can help you meet the water quality ...


  • Air/water cleaning for the control of particulate fouling

    Fouling of feed spacers in spiral wound membrane elements due to particulate fouling and biofouling is one of the main operational problems of nanofiltration or reverse osmosis membrane plants. Removal of particulate fouling from spiral wound membrane elements is investigated using frequent air/water cleaning (AWC). In a pilot setup two spiral wound elements were operated in parallel and were fed ...

  • Methods of Water Purification

    This article is excerpted from 'Pure Water Handbook' published by OsmonicsĀ®, 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 ...

  • Features of Reverse Osmosis (RO)

    1. Removal of dissolved salts  Reverse osmosis can stably and effectively remove dissolved salts, dissolved organic substances (trihalomethane, its precursors, agricultural chemicals, etc.), and micro fine particles (living germs, dead germs, and many other micro fine particles) from water. Thus it is ideal for a wide area of applications ranging from production of ultra pure water to ...

  • RO Feedwater: Treat It Right

    Summary Crossflow membrane filtration systems, such as reverse osmosis (RO), nanofiltration (NF) or ultrafiltration (UF), are good alternatives to traditional filtration and chemical treatment. However, to get the best performance from them, careful attention must be paid to feedwater conditions. Pretreating feedwater can lengthen the life of membrane elements, improve the quality of the ...

  • Oil refinery reduces energy consumption with a Culligan Solution

    Challenge A major petroleum refinery was looking to replace a hot lime softener. Naturally occurring minerals such as Calcium, Magnesium and Silica can cause scale in steam boilers and other types of equipment used in refinery operations. Scale deposits in steam boilers con reduce equipment efficiency and increase energy, chemical, disposal and maintenance costs. Hot lime softening is a ...
