Wastewater Treatment Insights

  1. Pride And Prejudice: A Philadelphia (Water Department) Story
    7/12/2018

    Recently, I had the opportunity to tour a unique and innovative facility, the Bureau of Lab Services (BLS), the “water quality heartbeat of the Philadelphia Water Department” (PWD), as described by BLS director Gary Burlingame.

  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. 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.

  6. Is There A Cure For Wastewater’s Summertime Blues?
    6/25/2018

    As we approach the hottest months of the year, wastewater treatment plant (WWTP) operators face a range of challenges arising from elevated summer temperatures. With all due respect to Eddie Cochran, this article outlines some of the cures — or at least preventive steps and countermeasures — for wastewater treatment’s “summertime blues.”

  7. Play It Again, Sam: Potable Water Reuse Striking New Chords
    6/21/2018

    The phrase “Necessity is the mother of invention” has been definitively traced back to early 16th century England, and even attributed to Plato in the Latin form, “Mater artium necessitas.” In today’s world of water, necessity is also becoming a major factor in rising interest regarding potable water reuse. This is especially true in areas where changes in climate or usage demands have stressed traditional sources of supply, as evidenced by increasing numbers of applications worldwide. For those who work in a water-stressed environment, this article can provide added perspective on specific points of opportunity — and points of caution.

  8. All-Natural Biofilm Media Derived From Plant Stock Enhances Clarifier Settling
    6/4/2018

    When clarifiers are not settling like they should, problems arise, including reduced capacities, high sludge volume indexes (SVI) and sludge blanket levels, and infiltration/inflow (I/I) washout issues.

  9. Point Level vs. Continuous Level Measuring Technologies
    5/14/2018

    While point level measuring approaches are regarded as simple and user-friendly, they lack the capabilities of more sophisticated continuous measuring instruments.

  10. How Sludge-To-Energy Technology Is Boosting Water Resilience And Slashing Emissions For Cities
    5/14/2018

    Growing cities are generating higher volumes of wastewater and putting a strain on clean water supplies, calling for solutions that extract value from “waste” and ensure the sustainability of resources — with the added bonus, or imperative, of protecting the environment.
