Drinking Water Application Notes

  1. The Basics: Keeping Our Water Clean Requires Monitoring
    4/30/2014

    Keeping the water in our lakes, rivers, and streams clean requires monitoring of water quality at many points as it gradually makes its way from its source to our oceans. Over the years ever increasing environmental concerns and regulations have heightened the need for increased diligence and tighter restrictions on wastewater quality.

  2. Application Note: Vertical Profiling Safeguards Drinking Water And Sheds Light On Cyanobacteria

  3. Wireless PRV Monitoring Application Note
    11/21/2013

    Pressure reducing valves (PRVs) are used throughout water distribution systems to reduce pipeline pressure to a predetermined set point. This decreases water loss and prevents pipe breaks.

  4. New Water Turbidity Measurement Technology — The US Experience
    2/3/2017

    The amount of insoluble matter present in drinking water is an essential quality indicator. Silt, sand, bacteria, spores, and chemical precipitates all contribute to the cloudiness or turbidity of water. Drinking water (DW) which is highly turbid can be unpalatable and unsafe. Consumption of even low concentrations of certain bacteria and other microorganisms can cause serious health effects. Consequently, an accurate and sensitive measurement of turbidity is vital for ensuring that drinking water is free of these contaminants.

  5. 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.

  6. Accurately Measuring Network Leakage
    6/26/2015

    The pressures of supplying a growing global population mean that the world’s water supplies need to be managed more closely than ever.

  7. Lab Gas Sub-Metering Accuracy Improves With Thermal Flow Meters To Save Money
    1/20/2016

    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.

  8. Application Note: Water Flows From The Golden Hills Of California

    Each morning John Johnson drives the few miles from his smalltown home in northern California to the Center at Pardee Reservoir. Nestled among the foothills of the Sierra Nevada mountain range, the reservoir is a long 100 miles away from San Francisco Bay. By YSI
  9. Technical Note: Using 3M Liqui-Cel Membrane Contactors To Solve Resistivity Problems In A High Purity Water Loop
    1/30/2009

    Pureflow, Inc. is a Southeastern-based expert in designing complete water treatment systems as well as providing value-added solutions for fixing operational issues in existing systems. Pureflow teamed up with Membrana to help solve an operational issue at one of their customer’s facilities. By Membrana

  10. Application Note: Desalination Plants: YSI Instruments Monitor Flow & Water Quality At Multiple Stages
    2/3/2011
    Desalination is the process of removing salt from sea water or brackish river or groundwater to make potable water. By YSI
