Drinking Water Application Notes

1. Dosing Of Sodium Hypochlorite Solution For Drinking Water Disinfection 9/22/2022

   A water purveyor was in urgent need of a chemically resistant flow instrumentation with a long life of service that allowed reliable and long-term stable dosing of the sodium hypochlorite solution.

2. Protecting Pumps From Dead Head Conditions 4/6/2017

   The C445 motor management relay offers the most configurable protection options in the industry, with features specifically designed to protect critical pumps from costly damages due to dead-head and other underloaded or starved pump conditions.

3. 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.

4. 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%!

5. Cloth Media Filtration Removes Coal Ash And Coal Fines At Power Plants 1/15/2019

   Coal-fired power plants generate coal fines and coal ash from a number of sources, including coal combustion residuals (CCR), particularly fly and bottom ash from coal furnaces, and coal pile runoff during rain events. In support of an industry-wide effort to reduce, improve, and remove coal ash ponds, a variety of technologies have been tested and employed. Read the full application note to learn more.

6. 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.

7. Determination Of Polar Pesticide Residues In Food Of Plant Origin, By And Automate QuPPe Solution 9/29/2014

   The QuEChERS (Quick-Easy-Cheap-Effective-Rugged-Safe) sample extraction method was developed for the determination of pesticide residues in agricultural commodities.

8. Application Note: YSI Real-Time Water Quality Monitoring And The IPSWATCH-EMPACT Program 12/28/2005
   The Ipswich and Parker Rivers watersheds lie only a short distance north of Boston, MA. The first settlements in these watersheds began in the early 1600s. Since that time, residents have relied heavily on the natural resources of the Parker and Ipswich Rivers, their coastal estuaries and Plum Island Sound, which is known as the Great Marsh. This ecosystem has been designated and protected by the Commonwealth of Massachusetts as an Area of Critical Environmental Concern (ACEC).
9. Operations And LRV Calculations At Southwest Pipeline Project Drinking Water Treatment Facility 4/14/2016

   This presentation will discuss the operation of a 4 MGD pressurized two-stage Ultrafiltration (UF) plant over a 14 month period at the Oliver-Mercer-North Dunn (OMND) Drinking Water Treatment Facility, North Dakota.

10. Phosphate In Groundwater And Surface Water: A Rapid And Reliable Determination Method Using The Photometric Spectroquant® Test 1/31/2019

    Phosphorus is an essential element for organisms and plants. In natural, uncontaminated waters, it occurs as organically bound phosphate, condensed phosphates or as orthophosphate — often referred to by its chemical formula PO₄-P. The small quantity of phosphorus present in natural waters does not promote the growth of plants. However, a rise in the concentration of phosphorus results in the proliferation of algae, which leads to the eutrophication of the water body.
