Wastewater Treatment Case Studies and White Papers

  1. Optimize Ozone For Wastewater Reuse

    Over the past several years, we've had overwhelming response and feedback to several articles we've written about using ozone for water and wastewater disinfection. The profound drought across many areas of the country has piqued interest in this wastewater reuse, and more specifically how ozone can play a role. This article answers some of the most common questions about ozone systems for wastewater applications. 

  2. Packaged Wastewater Treatment For Guantanamo Bay

    In 2001, with the growing population at Naval Station Guantanamo Bay, and expected future growth, a wastewater treatment system was needed to handle the increase in flows. Fluence worked directly with the United States Navy to design an advanced wastewater treatment plant to meet those needs. The intent was to supply four or five large packaged wastewater treatment systems at different locations around the base.

  3. Reliable Bar Screen Designs For Worst-Case Scenarios

    By their very nature, wastewater bar screens are intended to operate under some pretty tough conditions. When a storm surge hits, however, both the severity of conditions and the criticality of results ratchet up several notches.With heavy storms seeming to occur more frequently and with greater intensity, here are multiple points to consider while reviewing mechanical bar screen performance.

  4. Dry Pit Submersibles Lower Costs And Eliminate Unscheduled Maintenance

    A utilities department was experiencing frequent unscheduled maintenance visits and corresponding unbudgeted repair bills for the pumps at the township’s main pump station.

  5. New Developments In Thermal Dispersion Mass Flow Meters

    This paper describes a newly developed microprocessor-based thermal dispersion mass flow meter that uses four temperature sensing elements in its flow sensor instead of the traditional two elements and automatically manages changes in gas selection, gas temperature, gas pressure, and outside temperature.

  6. 100% Reuse: 5-Stage BNR And Secondary Clarification

    The Emerald Coast Utilities Authority (ECUA) manages water and wastewater treatment for Pensacola, FL, and surrounding areas. The 19-acre Main Street Wastewater Treatment Plant had been in operation since the 1970s and began to require many upgrades.

  7. Post-treatment Aeration Maintains Dissolved Oxygen In Effluent High-Solids Wastewater Prior To River Discharge

    The LeSourdsville WWTP in Butler County, Ohio, was required to meet their NPDES permit requirement of 6 mg/l dissolved oxygen at the plants Miami River outfall.

  8. Integrated Level Solutions For The Future

    Smarter measurement supports safer, more efficient and more sustainable operations, improving uptime and extending servicelife, whatever the industry sector.

  9. Is There A Correlation Between ATP And Other Traditional Microbiological Methods?

    Perhaps the most common question that we’re asked is how our ATP tests correlate with traditional microbiological methods.  Unsurprisingly, when people are used to getting their information in a certain way, they naturally want to know how a new method will stack up against it.  However, the mechanisms of culture-based techniques and ATP analyses are completely different, and in many ways, so are the results they produce. 

  10. Fixed-Film Treatment System Handles Fluctuating Population Changes With Ease

    A retreat and camp facility struggling with variable flow conditions and associated wastewater issues turns to a fixed-film treatment system designed just for that application. The results have far exceeded expectations: treatment quality surpasses permit levels and regular operation and maintenance requirements are at an all-time low.
