Wastewater Case Studies and Whitepapers

  1. Clearing Channels And Tanks Of Rag And Fiber Produces Benefits Beyond The Tanks 11/20/2017

    Reduction of ragging is merely one of the benefits the EscaMAX® Perforated Plate Screen bestows upon its implementer. But this is such a huge factor, that mitigating it brings night-and-day results in other areas such as reducing debris in the grit channel, increasing space for energy-producing biosolids in tanks, and releasing cleaner end products. 

  2. Finding The Best Bearing Solution For Water Treatment Blowers 9/2/2020

    Edward Paro of Sulzer compares the strengths and weaknesses of two rival turbocompressor technologies: air foil bearings and active magnetic bearings.

  3. 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.

  4. 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.

  5. Improved Pump And Seal Reliability When And Where It Really Counts 3/25/2015

    Replacing mechanical seals twice per year was difficult and expensive for Chester, IL, but a more serious problem occurred when the seals failed with the Mississippi River at flood stage and the sealed lift station underwater.

  6. Calculating ROI When Adding Zeta Potential To A Water Treatment Facility 9/1/2021

    Zeta potential (Zp) provides unbiased guidance on the correct dosage of flocculent chemicals by measuring the charge of the particles that need to be filtered. This measurement not only can replace time consuming and subjective jar testing, but can provide actionable data that can save significant chemical cost and extend filter run times. 

  7. Jar Testing Gets An Upgrade 6/7/2021

    Jar testing is a common laboratory procedure used at water and wastewater treatment plants. In a set of beakers a defined amount of water is mixed with varying amounts of coagulant, and through observation by a trained operator the optimal amount of coagulant can be determined.

  8. What Type Of Dewatering Box Should You Choose? 8/30/2023

    In this article, take a look at types of dewatering boxes, benefits, and their applications for various projects.

  9. Sulzer Helps To Dewater "Stuttgart 21," The Largest Deep Construction Project In Europe 6/19/2023

    Read about a dewatering project that includes 57 kilometers of new railways with 34 kilometers of tunnels and 25 kilometers of high-speed lines. 

  10. Eclipse Gear Pumps For Chemical Dosing: Middlesex Water Company 8/15/2024

    Pulsafeeder’s Eclipse pumps provide successful chemical dosing at the Middlesex Water Company in Highland Park, New Jersey.
