WASTEWATER FEATURES, INSIGHTS AND ANALYSIS

  1. How Calibration Impacts Flow Meter Performance
    7/12/2018

    Utility managers and operators rely on flow meters to provide critical information for process monitoring and control. They require and fully expect the flow data to be accurate and reproducible.

  2. Benefits Of Remote Access To Primary Wastewater Treatment
    7/12/2018

    A real-world, industrial application of remote process monitoring proves that a little technology can go a long way in terms of cost savings and process improvement.

  3. Innovative Water Use In An Urban Setting
    7/12/2018

    Rather than waiting on water scarcity and reacting to a crisis, the San Francisco Public Utilities Commission is forging its own future, and that of others, by blazing a trail of water-reuse practice and policy.

  4. Integration Of CFD Modeling In Wastewater Treatment Design
    7/12/2018

    This overview of computational fluid dynamic (CFD) modeling for wastewater treatment plant design reveals how it is applied to different system components, as well as why (i.e., the benefits) and when (in the design process) it should be applied.

  5. West Deptford Energy Station Becomes Model Of Highly Efficient And Sustainable Energy Generation
    7/11/2018

    Veolia furnished West Deptford Energy with a BIOSTYR® Biological Aerated Filter (BAF) and Hydrotech Discfilter system, allowing effluent from a municipal wastewater plant to be reused, with a treatment capacity of 7.35 MGD, in the operation of their new “green” energy station. 

  6. How To Avoid System Downtime When Installing Flow Meters
    7/11/2018

    Water and wastewater utilities rely on accurate flow measurement for important process controls. These may include recycle streams, chemical dosing systems, and other operational functions. In addition, regulators require utilities to measure certain flows, such as treatment plant influent and effluent and potable water pumping. Accurate flow measurement is also important for monitoring and reducing unaccounted-for water.

  7. Even Flow Secret To Clarification Success
    7/10/2018

    The key to high rate clarifiers such as inclined plate settlers is flow distribution says Tom Grubb, Regional Manager with Meurer Research. “Each inclined plate is like a miniature little sedimentation basin,” Grubb told Water Online in a recent Water Talk interview at AWWA’s ACE 2018. “To get good effluent quality, it’s critical that you have the same flow to each plate.”

  8. From Australia To California, Log Reduction Credits For MBR Systems
    7/10/2018

    Jon Loveland, Global Practice Leader - Alternative Water Supply at Black & Veatch, shares insight on a major development for membrane bioreactor (MBR) systems and potable reuse.

  9. The Challenge Of Flow Disturbances On Meter Accuracy
    7/10/2018

    Accurately measuring flow is critical for water utility operations. Also, regulatory agencies mandate flow monitoring and require annual calibration of meters. But even a meter in perfect condition and properly calibrated can read inaccurately. Flow disturbances are a common cause of accuracy and repeatability errors.

  10. Optimizing Tank Flushing Using A Rapid Decision-Making Framework
    7/5/2018

    In 2017, a municipal water treatment plant was commissioning a new elevated tank. The tank had been cleaned, flushed and disinfected, but initial test results indicated unacceptable water quality. After a second cleaning, the tank was refilled and water samples were sent to the lab for follow-up testing.
