Wastewater Case Studies and Whitepapers

  1. 10 Years After Installation, Insta-Valve 250 Helps Isolate Repair Area 9/20/2021

    A previously installed Insta-Valve 250 insertion valve provided control for a fire pump removal without backflow between the water distribution piping and the water treatment facility.

  2. Disruptive Technology Makes Ozone A Better Option 6/30/2020

    Sidestream injection (SSI) systems are shaking up the water treatment industry, unseating industry-standard fine bubble diffusion (FBD) systems by delivering fast, high-efficiency ozone transfer with a small footprint. 

  3. Keeping The Operator In Focus: The Four Pillars Of Operator Effectiveness 8/2/2018

    This paper shows how the four pillars of operator effectiveness lead operators to greater awareness, faster response and better decisions.

  4. Town Of Kittery, Maine Relies On Lime Feeders For pH Control For More Than 25 years 6/26/2017

    The Francis L. Hatch water filtration plant is in the coastal town in York county Maine and has an average capacity of 2.6 MGD. This is a surface water plant that utilizes hydrated or “slaked” lime (calcium hydroxide) to maintain the pH level around 7.0. For over 25 years, the district has used two of the UGSI Chemical Feed model 32‐055 Feeders to mix dry hydrated lime with water to create a lime slurry solution that can then be added to the finished water treatment.

  5. Why You Need To Be Prepared For The Next Superstorm (And How To Do It) 4/19/2023

    Understand why a storm preparedness plan is crucial to overcome challenges such as power outages and equipment damage. 

  6. Biologically Engineered BioFilm Modifications For The Enhancement Of Collection System Transformations And Impacts On BNR Wastewater Treatment 10/17/2006
    Increased influent RBCOD and heterotrophic plate counts coincided with the start of bioaugmentation in this study. Observed influent sulfide levels were also lower during bioaugmentation
  7. Using Green Infrastructure To Maximize Ecosystem Benefits 5/10/2022

    As part of an agreement with the EPA to reduce contaminated stormwater overflows from reaching the Mississippi river, the City of St. Louis, Missouri has enacted a $100 million grant program to support the installation of rain gardens and other types of green infrastructure across the city.

  8. Improved Mixing And Fine Bubble Aeration Help To Reduce Water Exchange, Shorten Production Cycle And Increase Overall Growth Rates 10/30/2019

    Finca Empacadora de Tilapia Milagro is one of the fastest growing and successful tilapia projects in Central America since its operation started in 2015.

  9. Converters: The Real Heroes Of Flow Measurement 7/17/2020

    Durable and reliable flow meters play a vital role in municipal water operations, but having the right converter to capture and transmit the resulting information is critical to maximize their value. Converters are expected to be robust and too often are taken for granted. Selecting the right converter to pair with your flow meters can make the difference in whether your data provides an average return on investment or the maximum benefit.

  10. Decreasing Lifecycle Costs: Don't Lose Dollars Chasing After Cents 10/27/2022

    This article explores some of the best practices to ensure overall station reliability, i.e., “total station efficiency,” in order to keep operating costs and downtime at a minimum.
