Water Instrumentation White Papers & Case Studies,

  1. Meters Monitor Flow And Provide Pump Protection
    12/15/2016

    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.

  2. ORP And pH — What You Don’t Know Can Hurt You
    11/15/2016

    When I look back at 2016 one of the most significant trends I observed was the growing acceptance of ORP measurements, especially for monitoring disinfection. With one caveat, the ORP value measured in a solution provides an unambiguous measure of the disinfection efficacy.

  3. United Water Solves Big Data Problem With Siemens Magnetic Flow Meter Technology
    11/15/2016

    United Water, a division of the global conglomerate Suez Environement, operates regulated water systems in eight states, and provides contract services to over five million people.

  4. Automated Wireless Monitoring Of Wastewater Collection Systems
    8/11/2016

    Telog Instruments, Inc. offers a comprehensive remote monitoring system, Telogers, for wastewater collection system operators. Telogers provides an automated system of collecting, archiving, analyzing, presenting, reporting and sharing data from collection system remote assets such as flow meters, rain gauges, CSO/SSO surcharge sensors, lift stations, pretreatment water quality, air quality, and pressure sensors.

  5. AMERICAN Pipe And Valves Ensure Georgia Project Flows With Ease
    6/29/2016

    The estimated $30-million West Side Loop 48-inch Replacement Project is one of three capital projects being conducted by the Cobb County-Marietta Water Authority to provide additional water to western Cobb County and Paulding County in Georgia. For the project, a 48-year-old, 36-inch pre-stressed concrete cylinder pipe (PCCP) that recently failed is being replaced with 48-inch ductile iron pipe.

  6. Ozone Vent Gas For Aeration At Wastewater Plant Expansion In China
    6/17/2016

    The Jimo, China, municipal wastewater plant was originally designed to treat a combination of municipal and textile wastewater (120,000 m3/d) with Class IB effluent limits for BOD, COD, ESS, TN, NH3-N and TP.

  7. Carbon Dioxide For pH Control Of Landfill Leachate
    6/16/2016

    A landfill operator’s leachate treatment plant in Missouri required pH reduction following lime-softening and prior to the biological wastewater treatment process. Carbon dioxide (CO2) was chosen as a substitute for sulfuric acid due to improved process control and a reduced tendency to form scale.

  8. In-Situ Oxygenation System Enables Increase In Capacity For Municipal Wastewater Treatment Facility
    6/16/2016

    To increase capacity within the existing footprint of a wastewater treatment facility in Michigan, two existing tanks were converted to aeration tanks with pure-oxygen aeration provided by Praxair’s In-Situ Oxygenation (I-SOTM) System.

  9. Monitoring Lead In School Drinking Water
    5/23/2016

    The EPA’s guidance documentation “3T’s for Reducing Lead in Drinking Water in Schools and Child Care Facilities: Training, Testing, Telling” recommends for schools to routinely test their facility’s drinking water, with a focus on lead levels in drinking water fountains.

  10. In-Situ Calibration: Methods And Pitfalls Of Thermal Mass Flow Meter Sensor Field Validation
    5/1/2016

    Mid-to-large size facilities and campuses inevitably have hundreds of flow instruments to monitor, maintain, and repair. For a reliability engineer, ensuring that all instrumentation meets ISO 9000 or similar standards is a time-consuming responsibility. By Matthew J. Olin, President & CEO, Sierra Instruments, Inc.
