Drinking Water Application Notes

1. 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.

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. Application Note: YSI Water Quality Monitoring Buoys Help Connecticut DOT Protect The Housatonic River
   12/27/2005
   When replacement of the Sikorski Bridge spanning the Housatonic River was authorized, Paul Corrente and the Connecticut Department of Transportation (CT-DOT) set about the design and development of a water quality monitoring program to monitor the contractor’s in-water activities to insure full protection of the river from perturbation
4. Application Note: Vertical Profiling Safeguards Drinking Water And Sheds Light On Cyanobacteria
   2/3/2011
   A search for algal toxins in North Carolina reservoirs has evolved into an ongoing early warning system for three important drinking water reservoirs—which serve two large cities—and yielded a greater understanding of the dynamics of blue-green algae, or cyanobacteria, in the state’s reservoir system. By YSI
5. 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
6. 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.

7. Measuring The Chlorine Content In The Emergency Chlorination Of Waterworks
   12/14/2011
   Many municipal waterworks perform no permanent disinfection of drinking water. However, in many cases a process known as emergency chlorination takes place. The process is switched on in case of need, adding chlorine to the drinking water as a disinfectant.
8. Lab Gas Sub-Metering Accuracy Improves With Thermal Flow Meters To Save Money
   12/1/2017

   Facility administrators will find the advanced ST100 Series Thermal Mass Air/Gas Flow Meter from Fluid Components International (FCI) helps them improve the accuracy of specialty gas point of use and sub-metering operations to achieve accurate billing in their labs for better cost tracking and control.

9. Real-Time Conductivity Monitoring Estimates Chloride Levels In Minnesota Watershed By Using The Aqua TROLL 200
   11/18/2011
   Monitoring deicing chemical levels can help researchers, city governments, and regulatory agencies understand runoff impacts on surface water, groundwater, and surrounding environments.
10. Hydrogen Sulfide Removal From Water Using AquaSorb® CX-MCA
    2/19/2014

    The “rotten egg” odor in some water supplies is caused by sulfide in water. Sulfide can be treated using oxidation techniques, the goal being to convert the sulfide to high oxidation state species such as sulfate to eliminate the taste and odor concerns. Traditional oxidation techniques such as ozone and chlorine can be used, but can be expensive due to the equipment required to add and monitor the oxidant, and can lead to by-products such as trihalomethanes (THMs), which are regulated in drinking water supplies.
