Drinking Water Treatment Application Notes

  1. A New Way Of Designing With Reverse Osmosis Membranes
    7/23/2015

    Process design in water treatment is historically confined to proprietary or user-defined spreadsheets on a unit operation basis, with users manually adding results from each unit process upstream into the next operation.

  2. Application Note: Busseron Creek Watershed Partnership Addresses Concerns In A Rural Watershed
    1/20/2010
    As with other watershed organizations, the Busseron Creek Watershed Partnership (BCWP) exists because of surface water quality degradation. In this case, those waters drain 163,231 acres of a watershed that crosses the boundaries of Vigo, Clay, Green, and Sullivan counties in West- Central Indiana. By YSI
  3. 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.

  4. Analyzing Total Organic Carbon In Sea Water
    4/2/2015

    The analysis of Total Organic Carbon (TOC) in seawater can be both challenging and expensive. The concentration of organic carbon in seawater is of considerable interest. The effect this matrix can have on TOC analyzers can lead to rapid consumable turnover, costly maintenance and repairs.

  5. Measuring The Chlorine Content In The Emergency Chlorination Of Waterworks
    12/14/2011
    Many municipal waterworks perform no permanent disinfection of drinking water. However, in many cases a process known as emergency chlorination takes place. The process is switched on in case of need, adding chlorine to the drinking water as a disinfectant.
  6. Non-Contact Radar Level Meter Improves Reactor Vessel Measurement
    7/4/2013

    A North Carolina-based specialty chemical manufacturer, a major producer of insect repellent, was looking for a better way to measure the liquid level in its glass-lined agitated reactor. The company uses a number of complex technologies to manufacture sebacates, adipates, isophthalates, catalysts, alkyds, and other natural and renewable chemistries based on castor and citrates.

  7. Application Bulletin: Reverse Osmosis
    3/19/2008
    Osmosis is the phenomenon of lower dissolved solids in water passing through a semi-permeable membrane into higher dissolved solids water until a near equilibrium is reached
  8. Application Note: Turbidity Monitoring In Drinking Water Treatment Plants
    8/30/2005

    Turbidity, or the relative clarity of a liquid (in this case drinking water), is caused by the presence of microscopic particles such as clay, silt, or other fine undissolved matter

  9. 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.

  10. Solution For Algae Blooms
    12/17/2015

    Harmsco® Filtration Products is pleased to offer a solution to the ever increasing blue-algae blooms in water sources. A multi-barrier approach is necessary to physically remove intact (algae and cyanobacteria) before they rupture in the treatment process and then remove extracellular cyanobacteria through adsorption.
