Drinking Water Application Notes

  1. Free Chlorine Measurement In Drinking Water Treatment 12/21/2005

    Before water can be used as a safe and reliable source for drinking water, it must be properly treated. Since water is a universal solvent, it comes in contact with several different pathogens, some of which are potentially lethal, and inactivation is accomplished through chemical disinfection and mechanical filtration treatment. This treatment consists of coarse filtration to remove large objects and pre-treatment which includes disinfection using chlorine or ozone

  2. Application Note: Troubleshooting A pH Electrode 1/26/2011

    Many factors affect performance of a pH electrode. When performance degrades, it is always a challenge for the analyst to identify the cause. Common troubleshooting procedures, which include evaluation of slope, electrode drift, time response, and accuracy, take considerable time. By Thermo Fisher Scientific

  3. TOC Analysis: The Best Tool In A Drinking Water Facility's Toolbox 5/3/2019

    SUEZ Water Technologies & Solutions designs and manufactures Sievers Total Organic Carbon (TOC) Analyzers that enable near real-time reporting of organic carbon levels for treatment optimization, quality control & regulatory compliance. TOC has a wide range of applicability at a drinking water plant, and therefore any drinking water utility — large or small — can measure TOC in their laboratory or online in their treatment process.

  4. Leak Detection On Water Distribution Network Using Clamp-On Flowmeters 5/22/2023

    A global engineering company realized that their leak identification methods were time consuming and expensive, and so began to explore alternative solutions, such as ultrasonic flow meters. 

  5. 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.

  6. Water Treatment In Boilers And Cooling Towers 10/29/2021

     Most people recognize problems associated with corrosion. Effects from scale deposits, however, are equally important. For example, as little as 1/8" of scale can reduce the efficiency of a boiler by 18% or a cooling tower heat exchanger by 40%!

  7. Determination Of Hexanal In Foods Utilizing Dynamic Headspace 4/9/2015

    Hexanal is one of many well-documented aromatic components that contribute to flavor and aroma in common consumer food products containing omega-6 fatty acids. Hexanal content is also used to measure the oxidative status of foods rich in omega-6 fatty acids.

  8. Why Should We Care About NSF/ANSI 61 Certification? 3/17/2021

    According to National Sanitation Foundation (NSF) and the American National Standards Institute (ANSI), it's a set of standards relating to water treatment and establishes criteria for the control of equipment that comes in contact with either potable water or products that support the production of water.

  9. LC-MS Analysis Of PFAS Compounds In EPA 533 After Supelclean™ ENVI-WAX SPE Cleanup 8/29/2022

    This application note demonstrates the extraction and subsequent analysis of 25 related analytes from water using Supelco SPE cartridges.

  10. 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.
