Drinking Water Treatment Application Notes

  1. Capturing Ammonia In Flue Gas Condensate Treatment For Biomass Power Stations With 3M™ Liqui-Cel™ Membrane Contactors
    8/10/2017

    Heat and power generation in biofuel engine cogeneration plants has become increasingly important as process industries look for more economical and environmentally friendly ways to produce energy.

  2. 3M™ Liqui-Cel™ Membrane Contactors Are Widely Used In The Soft Drink And Brewing Industries To Control Dissolved Gasses
    7/10/2017

    Gas control is an important concern in the beverage industry. Oxygen in the water can oxidize flavor components and shorten the shelf life of the product. Carbon dioxide can also have an impact on taste and pH of the product.

  3. Control Of Drinking Water Clarifiers

    "The variable concentration of solids when purging lamella clarifiers creates problems with sludge dewatering. These problems are exacerbated when changing the flocculant. Read the full application note to learn how automatic control of purge cycles for clarifiers using the Sonatax sludge level probe resulted in reduced energy consumption and maintenance at the plant."

  4. 3M™ Liqui-Cel™ Membrane Contactors Can Help Meet Pure Steam Requirements In Pharmaceutical Industry
    8/10/2017

    Pure steam is used in sterilization chambers as a common method to sterilize pharmaceutical products, such as equipment parts, instruments, containers and materials for sterile environments.

  5. Accurate Flowmetering For Enhanced Water Network Performance
    5/9/2017

    Being able to accurately measure both the quantity and rate of water passing through a water distribution system is crucial to gaining an informed understanding of overall efficiency. As such, achieving a measurement that is exact as possible can have a significant impact on key areas including supply planning, maintenance and resource deployment, leakage detection and rectification and the overall environment, in terms of controlling abstraction and reducing unnecessary draw on natural resources.

  6. A Comparative Study Of On-Line And Laboratory TOC Analyzers For Analysis Of Raw And Finished Drinking Water
    4/5/2013

    Total organic carbon (TOC) analysis is an important indicator of water quality throughout the drinking water treatment process. Raw source water is progressively treated in chemical coagulation, flocculation, sedimentation, and filtration steps to remove particulate matter and natural organic matter (NOM).

  7. Network Monitors Water Quality In Shale Gas Drilling Region
    9/2/2011
    High-pressure injection of water, sand, and chemicals that fracture shale deposits deep underground to free trapped natural gas is employed by drillers tapping the Marcellus shale beds, a geologic deposit that stretches from central New York to Virginia and contains gas believed to be worth hundreds of billions of dollars. By YSI
  8. Improved Determination Of Volatile Organic Compounds In Water By SPME And GC/MS
    6/21/2018

    The analysis of water for volatile organic compounds is important due to their toxicity. The current methods for this determination lack of sensitivity, selectivity or capability for automation. This paper presents the new ISO 17943 Standard using Solid Phase Microextraction (SPME) and GC/MS. The sample preparation by SPME enables limits of detection and easy automation of the whole method. GC/MS provides the required sensitivity and selectivity. This ISO Standard was validated by an interlaboratory trial, which results confirm the outstanding performance for this method.

  9. A Strategy For Optimizing Water Treatment Plant Performance Using Light Scatter Technologies
    6/7/2013

    Two new particle detecting technologies have been developed to help optimize filter performance at water treatment plants (WTP).

  10. Removal Of PFCs With Activated Carbon
    12/30/2013

    In recent years, various perflorinated chemicals (PFCs) have come under increasing scrutiny due to their presence in the environment, in animals, and in human blood samples. There are two major classes of PFCs: perfluoroalkyl sulfonates such as perfluorooctanesulfonic acid (PFOS) and long chain perfluoroalkyl carboxylates such as perfluorooctanoic acid (PFOA) and perfluorononanoic acid (PFNA).
