Drinking Water Treatment Application Notes

  1. Degassing Sea Water Has Never Been This Compact, Efficient, And Adaptable
    6/27/2017

    3M™ Liqui-Cel™ Membrane Contactors offer a modular skid option for off-shore oil platforms that is significantly smaller and lighter than traditional vacuum towers.

  2. Disinfection By-Products (DBP) Precursor Monitoring
    2/1/2013

    Chlorine has long been used as a primary disinfection method for many water and wastewater treatment applications. However, there is growing concern about the harmful DBP’s produced by the use of chlorine.

  3. Chemical Cost Comparison Of A Conventional Deaerator vs. A 3M™ Liqui-Cel™ Membrane Contactor System
    6/27/2017

    Mixed bed ion exchange is often used to polish reverse osmosis (RO) permeate in many industrial water systems. This process has been utilized for several years and it is well known that the management of the dissolved carbon dioxide (CO2) in the water is critical for an efficient operation. By Membrana

  4. Application Note: Using Real-Time Telemetry For Ecological Monitoring Of Coastal Wetlands

    The Grand Bay National Estuarine Research Reserve (NERR)in Mississippi is one of 27 protected estuarine reserves across the United States. By YSI
  5. Degassing Boiler Feed Water in China with 3M™ Liqui-Cel™ Membrane Contactors
    7/6/2017

    ShenLan Environment Inc. located in Shanghai, China uses 3M™ Liqui-Cel™ Membrane Contactors in their boiler feed water treatment systems. These systems realize lower operating costs with the added benefit of reducing the chemicals added to the boiler feed water.

  6. 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.

  7. 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).

  8. Dissolved Oxygen Measurement
    11/11/2013

    One of the most important measurements in the determination of the health of a body of water is its dissolved oxygen content. The quantity of dissolved oxygen in water is normally expressed in parts per million (ppm) by weight and is due to the solubility of oxygen from the atmosphere around us.

  9. Reverse Osmosis Application Bulletin
    5/3/2016

    Electrical conductivity is the most convenient method for testing RO water quality and membrane performance. Pure water is actually a poor electrical conductor. The amount of ionized substances (salts, acids, or bases) dissolved in water determines its conductivity. Normally, the vast majority of the dissolved minerals in tap, surface or ground water

  10. Control Of Drinking Water Clarifiers
    4/13/2017

    "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."
