Drinking Water Treatment Case Studies and White Papers

  1. Monitor Your Pump For Process Efficiency

    Pumps are all too frequently one of the most overlooked and abused pieces of equipment in process automation, yet nothing moves without them and a process becomes inefficient when they don’t operate properly or completely shutdown. 

  2. Ultrasonic Metering For Small Water Meter Applications

    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.

  3. Drinking Water Disinfection - Coquitlam Water Treatment Plant, British Columbia (Case Study)

    In 2005, in response to changes to the Canadian Drinking Water Quality guidelines, the Greater Vancouver Water District Board approved a proposal to upgrade the Coquitlam WTP with UV disinfection technology to act as the primary means of disinfection.

  4. How Larger Flow Meters Speak Volumes

    As the price of water continues to increase, errors in flow measurement are magnified for distribution networks that transport large volumes of water. These systems often incorporate meters over 48 inches in diameter, which can be a challenge to calibrate. Learn how choosing the proper calibration method can ensure the most accurate measurements.

  5. Harmful Algae: How To Stay Ahead Of The Bloom

    It’s the call no water treatment plant superintendent wants to receive, especially not while on vacation. Andy McClure, Superintendent of Toledo, Ohio’s Collins Park Water Treatment Plant, answered his phone to hear his head of operations report that the level of microcystin in the finished water was high, caused by a large harmful algal bloom (HAB) that was impacting the plant’s Lake Erie intake.

  6. Ultrasonic Vs. Radar Level Technology In The Water Industry

    In recent years, the debate about which technology is best suited for water and wastewater level measurement and monitoring is heating up. There are those who argue that ultrasonic level technology has been uncontested as the standard for level and open-channel measurement applications in the water industry.

  7. Integration Of Membrana Ultrafiltration And Gas Transfer Membrane Technologies Produces High Quality Water And Controls Corrosion In Cooling Water System

    By incorporating Membrana UF and Gas Transfer Membrane (GTM) a resort customer was able to reduce the risk of contaminating its cooling water and protect other system components from corrosion. The compact systems exceeded performance expectations and reduced maintenance and operating costs while maximizing the available space.

  8. Case Study: Aquatech Supplies One Of Most India's Largest Tertiary Treated Sewage Recycle Plants
    The water supply body in Mumbai having increased water charges to almost a dollar per cubic meter of water in year 1998-99, and the huge water quantities demanded for processing of fertilizers, RCF required a solution wherein it could effectively recycle the sewage water to be made available by the Municipal body. By Aquatech International Corporation
  9. Meters Monitor Flow And Provide Pump Protection

    A Municipal Water Plant in the Southeast United States treats and supplies potable water to a large metropolitan area. Part of the process requires accurate flow measurement of the water from individual pumps to the main distribution system. Part of the process requires accurate flow measurement of the water from individual pumps to the main distribution system.

  10. How To Clean, Inspect, And Calibrate pH Sensors

    Once a pH sensor is installed in the process and operating, how do you determine when it is time to take the sensor out of the process and do a cleaning, or a calibration? Does one perform both a cleaning and a calibration or just a cleaning, or just a calibration? By Fred Kohlmann - Analytical Product Business Manager
