Wastewater Case Studies and Whitepapers

  1. Register Today For The Newterra Webinar: The Ideal Oxidation Ditch Doesn't Use Rotors, Discs, Or Diffusers 3/9/2022

    Join Newterra for a free webinar! Newterra’s Aire-O2 Tri-Oval design and Triton-based retrofit packages are the most capital and operating-cost efficient, and process-effective solutions for virtually any Oxidation Ditch. The unique operational characteristics of the Aire-O2 solution produce an unbeatable combination of optimal hydraulic and aeration efficiency. Independent testing and installations around the world show proof.

  2. Protecting Water Resources: A Multifaceted Approach 11/7/2017

    As the cost of and demand for potable water increases, engineers, planners, and utilities need reliable, innovative methods for protecting this valuable resource. Cost-effective and environmentally sustainable wastewater collection and treatment systems are vital components in the water cycle and therefore require careful analysis. While there is no single solution for every site or community, traditional ‘big-pipe’ systems are rarely appropriate in sensitive environments; fortunately, today there are more options than ever to consider.

  3. Translating Aeration Efficiency Into Dollars 5/14/2019

    The hardest aspects of comparing efficiencies among submerged aeration technologies are the many variables in capital expense (CAPEX), operating expense (OPEX), and complexity of wastewater makeup. Here are five major categories for evaluating industrial wastewater aeration efficiency.

  4. DELUMPER® Aids in Polymer Production 11/10/2020

    Steel Fire Equipment in Ontario, Canada needed help with their polymer production. The plant produces polymer for fire extinguishers. The pneumatic production system processes chemicals that often clump and sometimes even form into stone. They needed a crusher that could break up these chunks or the material would not flow through the system and the entire process would come to a halt. Steel Fire also needed the machine to be able to handle their production rate of 3000 – 4000 pounds of material a day and be powerful enough to break up very hard chunks.

  5. Precision Under Pressure: Engineering Custom Solutions For Pipe Emergencies 9/29/2025

    Emergency pipe repairs demand speed and accuracy. Custom engineered fittings ensure reliability in non-standard conditions, minimizing downtime, avoiding costly damage, and restoring service with precision and efficiency.

  6. Video Case Study: SPIRALIFT® SR Provides Septage Receiving Solution 11/23/2020

    The Willits, California Wastewater Treatment Plant services over 10,000 residents and receives 750 loads of septage each year, but found they had a serious problem. Heavy septage from “honey trucks” was dumped by haulers into its wet well which clogged the plant’s pumps and caused flow channels to overrun. The plant also lacked oversight as to who was pumping and what was being pumped into its system. It could not control the pH level of the wastewater. 

  7. Easy And Trouble-Free Self Priming Centrifugal Pump Adjustments 12/18/2012

    Most manufacturers employ a semi-open impellers in their self priming centrifugal sewage and trash pump designs. While other types of impellers, (enclosed, open or recessed), are sometimes used, this type of impeller has a proven field record for clog resistance and high efficiency. By Kevin Clemons

  8. Coal Yard Runoff Compliance Using Actiflo® Technology 3/6/2015

    Storm water runoff from a 37-acre coal storage yard utilized as part of daily operations at an industrial site in Southwestern Pennsylvania posed a problem when the Pennsylvania Department of Environmental Protection (DEP) updated the facility’s NPDES permit.

  9. The Top Seven Ways The STRAINPRESS® Helps With Digester Debris Issues 1/15/2024

    Read about the seven ways that the HUBER Sludge Cleaner STRAINPRESS® saves money and time while establishing a safer work environment.

  10. Sulzer Equipment Increases Wastewater Treatment Capacity And Efficiency 6/28/2023

    After twelve years of operation, a modernization of a WWTP was needed for the removal of nitrogen and phosphorous pollutants, as well as an enlargement by another 100’000 PE (population equivalent).
