Drinking Water Application Notes

1. 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.

2. Application Note: Continuous Monitoring Of Drinking Water Provides Assurance Of Safety 9/28/2005
   A water utility in Ohio wanted to learn more about the variability of water quality parameters such as pH, ORP, turbidity, and chlorine. Previously, most of these parameters had been measured by spot sampling protocols with only a few measurements during a daily period. In order to more accurately assess the water variability, the utility used a YSI 6920DW Drinking Water Multiprobe
3. Flow Monitoring At Sea Water Reverse Osmosis Plant Improves Water Distribution 1/6/2025

   Read about a desalination plant that was in need of a practical verification methodology for permanent and/or temporary (portable) solutions on large pipes.

4. Immediate pH Correction For Fluctuating Flow 2/19/2014

   In a number of water, wastewater and industrial process applications, pH is one of the most critical and highly sensitive analytical measurements.  Examples of critical pH applications include: Reverse Osmosis (RO) systems in which a controlled feed of caustic solution is typically added to the feed stream in order to convert a portion of dissolved carbon dioxide into bicarbonate precipitate allowing for removal by the RO membrane.

5. The Basics: ORP and Free Chlorine Monitoring 5/13/2014

   Oxidation Reduction Potential or Redox is the activity or strength of oxidizers and reducers in relation to their concentration. Oxidizers accept electrons, reducers lose electrons. Examples of oxidizers are: chlorine, hydrogen peroxide, bromine, ozone, and chlorine dioxide. Examples of reducers are sodium sulfite, sodium bisulfate and hydrogen sulfide. Like acidity and alkalinity, the increase of one is at the expense of the other.

6. Irrigation Technology In Agriculture: How New Technologies Overcome Challenges 1/29/2019

   As the world’s population continues to increase at a fast pace, more food and water will be needed to sustain humanity. In the past 50 years, we have tripled our need for water and food, and there are no signs of this trend slowing down. As a result of these conditions, smart, innovative agricultural practices are needed now more than ever. Technology can, and already does, aid agriculture in innumerable ways. One prominent part of agriculture that can use technological innovation to increase efficiency and effectiveness is irrigation.

7. SensyMaster Thermal Mass Flowmeter 8/3/2021

   SensyMaster helps to improve the operating costs of the most cost intensive process in sewage plants: Aeration. High-measuring performance and state of the art technology helps customers increase plant efficiency.

8. LC-MS/MS Analysis Of PFAS Extractables In Polyethersulfone Syringe Filters Using EPA 537.1 5/18/2022

   A key consideration for any PFAS method is to avoid contamination that can impact the accuracy of data, including those coming from sample preparation techniques such as filtration.

9. 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

10. Ultrasonic Level Measurement In Water And Wastewater Plants 5/19/2016

    Radar technology is often viewed as the “best” method of level measurement, but this isn’t necessarily true in the water industry.
