Wastewater Case Studies and Whitepapers

  1. Anammox Sidestream Deammonification Process Allows Plant To Reduce Capital And Infrastructure Costs 9/23/2020

    Pierce County’s main goal was to reduce the discharge of nitrogen to Puget Sound while also reducing plant operating costs while in nitrogen removal mode. After upgrading, the new system continues to remove greater than 80 percent of ammonia and 75 percent of total inorganic nitrogen, equating to a reduction of over 400 tons per year of nitrogen loading to Puget Sound.

  2. Center Feed Drum Screen Is Mission Critical To MBR Plant 12/23/2014

    Huber’s center-feed drum screen was recommended as the best technology to prevent wash around that can ruin the membrane bioreactor at a WWTP in Las Vegas.

  3. 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.

  4. Keys To Improved Quality And Flow Accuracy In Industrial Effluent Applications 8/2/2021

    To ensure regulatory compliance and protect infrastructure, local wastewater utilities are increasingly requiring industrial operations to provide them with quality and flow monitoring information before discharges reach the utility. Industrial companies can be proactive toward this obligation — in turn, saving money and avoiding compliance issues — by collecting the most accurate data in near real-time.

  5. Better Drinking Water Quality Starts Upstream 1/12/2021

    While every potable water treatment process requires a balance of chemistry and biology to deliver safe, clean drinking water, added concerns from upstream stormwater or agricultural runoff only make the job that much more difficult. How can we do a better job of safeguarding water treatment plant (WTP) operations while protecting the health of water utility customers against threats of upstream nonpoint source (NPS) pollution?

  6. Comparing Sludge Removal Systems For Water Treatment Plants 5/12/2022

    Due to limited clearance and accessibility, effective removal of settled sludge beneath tube settlers has long been a challenge for plant owners and design engineers. They needed a sludge removal solution with a low-profile design that would offer flexibility during operation and maintenance.

  7. A New Paradigm In Aeration Technology 5/13/2014

    The DO2E organization sprang from one individual’s attempt to solve an aeration problem in a fish hatchery and realizing that his device to do so had many other applications as well. This device broke up algal blooms as well as aerating, and it was only a short step to modify it into breaking up FOG (fats, oils, and grease) deposits in grease traps and lift stations. This device was patented, thus DO2E was born.

  8. Bioloop Retrofit Reduces Energy Consumption By 43 Percent 3/31/2015

    When a broken shaft caused a malfunction in one of the brush aerators at the village of Liberty, NY, WWTP, the village worked with its engineers to develop a plan for repair and upgrade.

  9. Can Heavy Rain Cause Sewer Backup? 9/9/2024

    Heavy rain is a fact of life in most areas around the world. While it can be refreshing and calming to see, it also brings with it a number of issues that have to be considered. 

  10. Location, Location — The Key To Aeration 5/17/2019

    As with any industrial process, the right tool for the job depends on the nature of the task at hand. In aerobic wastewater treatment, that optimal choice often comes down to a balance between the biological and financial demands of the application. Either way, here are several performance comparisons of how multiple aeration methods and locations stack up in industrial wastewater treatment applications.
