Drinking Water Measurement White Papers and Case Studies

  1. Are Test Strips Still Relevant For Water Analysis?
    9/26/2017

    Today’s environmental laboratories are audited and accredited companies where quality control (QC) and quality assurance (QA) reign. Advanced technology is needed to measure parameters for regulatory compliance down to parts per billion. In a world of regulatory mandates, can test strips still be used for water analysis?

  2. Precise Biogas Flow Measurement
    4/25/2016

    As oil prices remain high, we are in the midst of a nation-wide initiative to seek renewable sources of energy to increase energy efficiency and energy security. Renewable energy accounted for 13.2% of the domestically produced electricity in 2012. Among the sources of renewable energy is the production of biogas from landfill gas (LFG) or digester gas.

  3. Making Turbidity Readings Consistent, Reliable, And Compatible
    1/23/2019

    When water treatment plant (WTP) instrument readings impact regulatory compliance, any discrepancy between laboratory and inline instrument readings can be disconcerting. Fortunately, improved sensor technologies and Mobile Sensor Management capabilities can enhance operator confidence in managing the significance of those readings throughout WTP processes.

  4. Why A Little Knowledge About Sensors Can Be A Dangerous Thing
    6/4/2014

    Every day our technical support people answer questions on the selection of sensors for pH, ORP, conductivity, dissolved oxygen and turbidity. No issue generates more confusion than cell constants for conductivity sensors. The vast majority of returns we process are for conductivity sensors that were ordered with the wrong cell constant. It turns out that cell constants are something that we all read but that most of us don’t really understand. Pick the wrong cell constant for a probe and your analyzer will happily give you numbers to 3 significant digits. The only problem is those numbers are wrong.

  5. What's Faulty — Your Treatment Or Your Testing?
    9/29/2017

    The primary reason for laboratory testing at a water or wastewater plant is to determine if the facilities are meeting regulatory limits. Both proper operation and accurate testing are of utmost importance to ensure compliance. However, regulators and operators must consider limitations of the test methodology, as they may affect analysis results. The last thing any plant manager wants is unwarranted problems as a result of faulty analysis.

  6. Northshore Utility District Boosts Reading Efficiency By More Than 900 Percent, While Improving Customer Service
    9/19/2013

    When Northshore Utility District began searching for a new meter reading solution in 2006, achieving a strong return on investment was a critical factor in its selection process.

  7. Ultrasonic Metering For Small Water Meter Applications
    9/19/2013

    For many years, ultrasonic metering has been utilized for large scale liquid and gas measurement. However, it is a relatively new technology for small meter applications — particularly those designed for potable water.

  8. Keep Your Pumps Running Smoothly To Optimize Process Efficiency
    12/1/2017

    Industrial pumps consume up to 20% of the world’s energy production and can be responsible for 25 to 50% of a process plant’s energy bill, according to Europump, the Hydraulic Institute and other sources. Nothing moves without them in a process plant, and they are expensive to purchase, maintain and even more to repair or replace. Reducing pump lifecycle costs (their purchase, operation and maintenance) is critical in a process plant optimizing efficiency and product output. The process and the surrounding equipment configuration can be responsible for unnecessary high pump lifecycle costs.

  9. Integrated Automation Solution Eases Water And Wastewater Operations
    3/11/2013

    The water and wastewater industries face challenges at every turn — from population growth to strict environmental and financial regulations to downsizing. The complex nature of both industries puts a great deal of pressure on plant operators, who typically tackle tasks manually. Download this datasheet to learn how integrated automation software delivers improved reliability and flexibility throughout the entire operation. 

  10. Optioneering Helps MidCoast Water Transform Gloucester Water Network Into A Reliable, Efficient System
    12/1/2015

    MidCoast Water delivers water and sewerage services to 40,000 households in the Manning, Great Lakes, and Gloucester communities of New South Wales in Australia. It also supplies 8 billion liters of water a year to Karuah in the south, Crowdy Head in the north, and Gloucester in the west.
