Wastewater Case Studies and Whitepapers

  1. The Benefits Of Virtual Modeling In Wastewater 4/21/2023

    In this article, learn how photogrammetry can be used to give operators a virtual glimpse at underground infrastructure, helping them better plan repairs and rehab work. 

  2. Michigan Utility's New Pumps Underscore Advancements In Wastewater Handling 3/18/2014

    Ypsilanti’s pumps, originally put into service in 1982, became priority candidates for replacement after operating ten years beyond their expected 20 year service life. The Ypsilanti Community Utilities Authority (YCUA), included the project in the utility’s Master Plan.

  3. BOD Interceptors: Transforming Wastewater Treatment Plants Into Renewable Energy Resources 2/12/2014

    In communities across the United States, wastewater treatment plants are consuming vast amounts of energy to remove and dispose of energy rich organics. As any government comptroller can attest, the cost of the energy required to run a conventional activated-sludge treatment plant takes up a large portion – up to 40% – of a municipality’s budget.  Ironically, the very substance being treated could produce more than enough energy to run the treatment plant itself.

  4. Upgrading A 100-Year-Old Pump Installation In New Orleans 3/9/2021

    Finding just the right pump for an application can be quite a challenge, especially when the building presents several constraints. Sulzer updated a near antique installation.

  5. 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.

  6. The "Design For Autonomous Net-Zero Water Buildings" Project Funded By NSF 8/24/2015

    The students at the University of Miami will know firsthand the importance of rethinking the way we handle wastewater and water with a Net-Zero water treatment system on site.   The project showed the viability and feasibility to take buildings off the water grid to provide water recycling and how it can be achieved without raising the cost of high quality water.

  7. Optimizing Aeration For Nutrient Removal: A Deep Dive Into Jet Aeration's Role 12/22/2025

    Jet aeration improves nutrient removal by delivering superior oxygen transfer, intense mixing, and flexible process control—cutting energy use, enhancing BNR performance, and supporting long-term operational reliability.

  8. Workhorse Screens Benefit Cedar City 10/21/2020

    During 26 years at Utah’s Cedar City Wastewater Treatment Plant, Eric Bonzo says he’s seen it all – including, as most people working at the sharp end of the industry will testify, things he wishes he’d never seen.

  9. Replacement Vacuum Feeders For Hypo Treatment End Heavy Feeder Maintenance Burden At WWTP 4/30/2014

    The instrumentation supervisor for the City of Baltimore, MD’s 150-MGD Back River wastewater treatment plant (WWTP) reports that replacement of problematic vacuum feeders with more advanced vacuum feed units has ended heavy maintenance burdens associated with sodium hypochlorite (hypo) treatment of plant effluent.
