  1. Not All Sprockets Are The Same 5/12/2022

    There is a common misconception that all sprockets are the same, simply because they have the same number of teeth and run on 720-series chain. There are a number of other features that distinguish between a long-lasting, wear-resistant gear and a sprocket that needs to be replaced after a few years due to wear or failure.

  2. MBBR Technology Helps Plant Maintain Discharge Compliance, Achieve Sustainable Growth 8/18/2020

    A bacon processing plant in the Midwest was overloaded by more than 50%. Even though the system continued to maintain compliance, the plant proactively decided to expand its wastewater treatment facility to ensure they met their growing demand and maintained their standing as exemplary corporate citizens and environmental stewards.

  3. How Turbo Aeration Blowers Optimize Wastewater Treatment Efficiency 9/30/2024

    To operate at peak efficiency, the implementation and operation of high-speed turbo aeration blowers should consider proper blower sizing, sequencing, and control.

  4. Green Stormwater Infrastructure Is Having Its Day 8/13/2020

    Not long ago, systems engineered to manage and mitigate stormwater runoff were predominately of the “gray” variety. Today, however, more and more municipalities are embracing green stormwater infrastructure (GSI).  

  5. Coming Clean With The Environment 8/18/2013

    With population and energy costs rising, Long Island wastewater treatment plants figured out a cost-effective way to control pollution and conserve resources. By Jon Richens, senior process engineer, WesTech Engineering

  6. Using ATP And NGS To Monitor Nitrification 10/28/2020

    China Steel Corporation, a steel producer in Taiwan, produces wastewater that is high in organics, ammonia, solids, and other waste products. The wastewater is treated on-site using a series of biological treatment processes. The variable influent quality can make it challenging to meet treatment objectives.

  7. Plant's Aeration Output Increased While Electricity Is Decreased 8/14/2013

    Located in New Haven County, Connecticut, in the eastern USA, the wastewater treatment plant in Meriden has a design inlet flow of 43,911 m3/day (11.6 mgd) with a maximum inlet flow of 143,386 m3/day (38.0 mgd). Upgraded in the 1960s and 1980s, the plant has been in existence since the 1800s.

  8. Work Smarter, Not Harder: The Phased Assessment Strategy For Sewers (PASS) 2/21/2023
