Drinking Water Application Notes

91. 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
92. The 'First Line Of Defense' In Protecting Membrane Filters 8/9/2019

    Multi-element, self-cleaning pretreatment filters optimize membrane filter life and production while minimizing maintenance and downtime.

93. VFD Energy Savings For Pumping Applications 4/6/2017

    In the early days of variable frequency drive (VFD) technology, the typical application was in process control for manufacturing synthetic fiber, steel bars, and aluminum foil.

94. Reduced Bore Electromagnetic Flowmeter 10/29/2021

    Being able to accurately measure both the quantity and rate of water passing through a water distribution system is crucial to gain an informed understanding of overall efficiency. As such, achieving a measurement that is exact as possible can have a significant impact on key areas. This includes supply planning, maintenance, resource deployment, leakage detection and the overall environment.

95. Application Note: Using Real-Time Telemetry For Ecological Monitoring Of Coastal Wetlands 2/3/2011
    The Grand Bay National Estuarine Research Reserve (NERR)in Mississippi is one of 27 protected estuarine reserves across the United States. By YSI
96. Drinking Water Testing By Ion Chromatography Using Ultrapure Water 9/29/2022

    This application note demonstrates the suitability of ultrapure water produced by a Milli-Q IQ  7000 water purification system for the IC analyses of inorganic ions and DBPs in drinking water.

97. Circuit Board Cleanliness Testing 10/29/2021

    Contamination of circuit boards can bring about severe degradation of insulation resistance and dielectric strength. Cleanliness of completed circuit boards is, therefore, of vital interest. For those companies who have established circuit board cleaning procedures, the MIL Spec P-28809 has been used as a guideline for control. Now a simple "on line" test for the relative measurement of ionic contamination has been developed.

98. Biofouling Control In Cooling Towers With A Halogen Stabilizer 10/22/2020

    Biofouling in cooling towers is undesirable because it can reduce heat transfer efficiency, restrict water flow, and accelerate corrosion rates. Of even greater concern is the fact that pathogen growth in cooling towers can lead to disease transmission. Given the favorable growth environment of a cooling tower, these microorganisms can reproduce, proliferate and form complex biofilm communities. Legionella bacteria, which cause Legionnaires’ disease, are one of the greatest concerns from a public health standpoint because infections are often lethal and cooling towers are the most frequently reported non-potable water source of Legionnaires’ disease outbreaks (Llewellyn 2017).

99. 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.

100. Reduce Or Eliminate Water Hammer With Valve Positioners 5/19/2022

     Water hammer, which can occur in just about any pumping system and even steam systems, can lead to pipe breakage, equipment damage or even total system failure. Addressing water hammer at the source is the savviest and most cost-effective way to handle the issue.
