Drinking Water Application Notes

  1. (E)-2-Nonenal In Beer
    4/5/2015

    Numerous compounds contribute to changes in beer flavor as it becomes stale. One of these compounds, (E)-2-nonenal, has been investigated as a major source of the papery/cardboard flavor that develops in aged beer.

  2. Water Determination In Liquefied Petroleum Gas Using GC BID And Ionic Liquid Column Watercol™
    6/28/2018

    Water in petrochemical feedstocks can cause problems for processors. Freezing of pipe lines and valves and poisoning of expensive catalysts are just a few examples.

  3. 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.

  4. Active Energy Control – Energy Reductions Of Up To 10% Above Standard Drives
    4/1/2017

    Energy costs continue to increase. At the same time, there is increased pressure to reduce utility bills without sacrificing operations or comfort.

  5. Application Note: Employing Best Water Quality Monitoring Practices To Reduce Runoff During Construction
    8/4/2011
    Under proposed EPA stormwater runoff guidelines, construction site operators will be required to actively monitor or sample stormwater discharges daily. The enhanced effluent rules take effect in August 2011 for construction sites that disturb 20 or more acres and February 2014 for sites that disturb 10 or more acres, and they may stipulate a strict numerical limit of less than 280 NTU for average turbidity (sediment in water) on any day.

  6. Control Of Active Chlorine Disinfection By-Products (DBPs) Of Drinking Water Using The THM Plus Method
    4/13/2017

    Determining trihalomethane levels using standard analytical methods requires expensive equipment and highly qualified personnel, which also means that analysis costs are very high. For these reasons, trihalomethane analysis poses a serious problem for companies that supply drinking water. Read the full application note to learn how two drinking water laboratories improved quality control of water delivered to end users.

  7. How To Read An Encoder
    9/13/2013

    The HR-E LCD encoder has a 9-digit Liquid Crystal Display (LCD) to show consumption, flow and alarm information. The display automatically toggles between 9-digit and 6-digit consumption, rate of flow and meter model.

  8. 1,2,3-Trichloropropane (1,2,3-TCP) Application Brief
    2/4/2016

    Previously TCP has been used as as a degreaser, paint remover, and cleaning agent. Currently TCP is utilized as a chemical intermediate in the manufacture of various organic chemicals.

  9. The Basics: Keeping Our Water Clean Requires Monitoring
    4/30/2014

    Keeping the water in our lakes, rivers, and streams clean requires monitoring of water quality at many points as it gradually makes its way from its source to our oceans. Over the years ever increasing environmental concerns and regulations have heightened the need for increased diligence and tighter restrictions on wastewater quality.

  10. 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.
