Drinking Water Application Notes

  1. 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.

  2. Bringing Efficiency And New Confidence To BOD₅ Analysis
    2/4/2013

    Biochemical Oxygen Demand (BOD) analysis is the test everyone loves to hate—and for compelling reasons.

  3. (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.

  4. Chinese Chemical Plant Optimizes Water Treatment By Replacing Double Pass RO With A Single Pass RO And 3M Liqui-Cel Contactor System
    6/1/2016

    Electrodeionization (EDI) is widely used in many industrial water treatment systems throughout the world. In order to maximize the operating stability and life expectancy of an EDI system they were often designed with double pass RO using caustic injection pretreatment.

  5. 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.

  6. Flow Meter Enhances Chlorination System Performance For Municipal Water Department
    12/12/2017

    The water municipality at a mid-size city in the Western region of the U.S. serving a population of about 180,000 people needed to address a chlorine disinfection system problem at one of its water treatment plants.

  7. Improved Efficiencies In TOC Wastewater Analysis For Standard Method 5310B And EPA Method 415
    10/16/2014
    Total organic carbon (TOC) measurement is of vital importance to the operation of water treatment due to organic compounds comprising a large group of water pollutants. TOC has been around for many years, and although it is a relatively simple analysis in theory, operational efficiency is paramount.
  8. New Water Turbidity Measurement Technology — The US Experience
    2/3/2017

    The amount of insoluble matter present in drinking water is an essential quality indicator. Silt, sand, bacteria, spores, and chemical precipitates all contribute to the cloudiness or turbidity of water. Drinking water (DW) which is highly turbid can be unpalatable and unsafe. Consumption of even low concentrations of certain bacteria and other microorganisms can cause serious health effects. Consequently, an accurate and sensitive measurement of turbidity is vital for ensuring that drinking water is free of these contaminants.

  9. 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.

  10. Innovative Solutions To Drinking Water Decontamination In Small And Medium Treatment Plants
    9/21/2017

    Air stripping technology effectively removes VOCs, THMs, and CO2 for improved adherence to water quality regulations.
