Drinking Water Treatment Application Notes

  1. Determination Of Pesticide Residues In Tea
    4/10/2015

    In 2012, Americans consumed well over 79 billion servings of tea, which is just over 3.60 billion gallons.

  2. All WirelessHART Devices Are Not Created Equal
    12/4/2015

    Though they all must support routing functionality, some devices do it better than others.

    Routing consumes more energy, so the lifetime of the battery will be affected.  Therefore, a device with a battery that is inexpensive, has a long lifetime, and is easy to change would be ideal. With all this considered, a WirelessHART temperature transmitter is a suitable option to operate as a repeater.

  3. Application Note: Ozone Measurement In Potable Water
    3/1/2010

    Ozone is a powerful oxidizing agent that can be used to destroy the organic compounds that affect the taste and odor of potable water. Environmental concerns have led to increased use of ozone because, unlike chlorine, it does not form hazardous by-products.

  4. Organics Monitoring (TOC)
    2/1/2013

    Total organic carbon (TOC) testing is the traditional method for determining organic matter in water. However there is a far more practical, affordable and often more useful way to measure organic matter. UV absorbance testing (UVA) is rapidly becoming the preferred method of measuring organics even when the levels of organics being measured are very small.

  5. Preliminary Assessment Of Water Quality In Riviera Grise Near Port-Au-Prince, Haiti
    10/17/2012

    The Riviera Grise drains water from the Cul-de-Sac watershed, Haiti, which covers most of the rural areas along the flood plains and areas that extend into steep hillsides. It also covers urban areas of Port-Au-Prince, the capital city of Haiti.

  6. Veterinary Drug Residue Analysis Using The AutoMate-Q40: An Automated Solution To QuEChERS
    10/1/2014

    QuEChERS is a Quick-Easy-Cheap-Effective-Rugged-Safe extraction method that has been developed for the determination of pesticide residues in agricultural commodities.

  7. Secret To Disinfection Monitoring For High Chlorine Residual Wastewater Applications
    8/2/2015

    Some wastewater applications require chlorine residuals greater than can be effectively monitored using DPD due to the oxidation of the Wurster dye to a colorless Imine. Such applications include industrial wastewater processes that inherently have a high chlorine demand thereby requiring a more robust monitoring method.

  8. Ultrapure Water For Determination of Toxic Elements In Environmental Analyses
    4/10/2018

    In this paper the importance of reagent water quality for toxic element environmental analyses is discussed, and the suitability of fresh ultrapure water produced using MilliporeSigma water purification systems for ICP-OES and ICP-MS trace element analyses in environmental laboratories is demonstrated.

  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. 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
