Drinking Water Application Notes

  1. Application Note: YSI 600 Optical Monitoring System Used To Protect Lake Oconee, Georgia Water Quality
    12/27/2005
    Northern Georgia is experiencing unprecedented development; consequently, water quality in many of its watersheds is in jeopardy of severe degradation. The State of Georgia, Environmental Protection Division (EPD) has implemented an NPDES monitoring and enforcement program designed to prevent construction activities from impacting water quality
  2. Application Note: Troubleshooting A pH Electrode
    1/26/2011

    Many factors affect performance of a pH electrode. When performance degrades, it is always a challenge for the analyst to identify the cause. Common troubleshooting procedures, which include evaluation of slope, electrode drift, time response, and accuracy, take considerable time. By Thermo Fisher Scientific

  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. Chlorine Method For UKAS Accreditation And DWI Compliance At Welsh Water
    4/13/2017

    In 2013 the Drinking Water Inspectorate for England & Wales announced that water samples collected in England and Wales must be tested in a laboratory that meets specific standards for drinking water sampling and analysis. At the time of the new instruction, the chlorine method employed at the Welsh Water Bretton laboratory was unable to meet these requirements, notably for the prescribed limit of detection. This prompted the laboratory to investigate new analytical options for monitoring residual chlorine.

  5. Application Note: Busseron Creek Watershed Partnership Addresses Concerns In A Rural Watershed
    1/20/2010
    As with other watershed organizations, the Busseron Creek Watershed Partnership (BCWP) exists because of surface water quality degradation. In this case, those waters drain 163,231 acres of a watershed that crosses the boundaries of Vigo, Clay, Green, and Sullivan counties in West- Central Indiana. By YSI
  6. A Strategy For Optimizing Water Treatment Plant Performance Using Light Scatter Technologies
    6/7/2013

    Two new particle detecting technologies have been developed to help optimize filter performance at water treatment plants (WTP).

  7. Air / Gas Mass Flow Meter Improves Wastewater Treatment Processing Efficiency
    12/15/2017

    One of the most common processes in wastewater treatment is the activated sludge method, which biologically treats the wastewater through the use of large aeration basins. This process requires the pumping of compressed air into the aeration basins where a diffuser system ensures the air is distributed evenly for optimum treatment. The energy needed to provide compressed air is a significant cost in the operation of a wastewater treatment plant.

  8. 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.

  9. Thermal Flow Meters For Mixed Gas Applications
    5/22/2017

    Fox Thermal Flow Meters use a constant temperature differential (constant Δ T) technology to measure mass flow rate of air and gases.

  10. Determination Of Pesticide Residues In Honey, By An Automated QuEChERS Solution
    9/17/2014

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