Wastewater Case Studies and Whitepapers

  1. The Cost Of High Solids In Your Wastewater Treatment Plant 2/12/2018

    Conventional activated sludge wastewater treatment plants (WWTP) operate with solids (mixed liquor suspended solids ­– MLSS) concentrations ranging from approximately 1500 to 5000 mg/L. In membrane bioreactors (MBRs), typical MLSS concentrations are even higher (10,000 to 12,000 mg/L). 

  2. Acoustic Sewer Inspection Saves Oakland, Maine, Time And Money 9/20/2024

    Discover how the SL-Rat program realized over $51,000 in crew labor and financial savings, while reducing the risk of sanitary sewer maintenance issues, for the town of Oakland, Maine.

  3. Easy To Digest: H2S Removal Rids City Of Lift Station Odors 8/11/2017

    A constant problem in many wastewater collection systems is the formation of hydrogen sulfide (H2S) in the lift stations as well as from biofilms further downstream in the delivery piping to the wastewater treatment plant. DO2E representatives suggested that the City of Taylorville (IL) use their proprietary digesters equipped with an ozone (O3) capability to remove this problem from our system.

  4. Grinders, Shredders And Comminutors – An Evolving Technology 11/20/2020

    Comminution technology has been evolving quite rapidly in response to the increasing burden entrained solids have placed on treatment facilities. More advanced devices have been developed in rapid succession. The result has been an exciting and fluid race between the leading manufacturers to develop the best size reduction device. The latest grinder innovations to be introduced have coupled the power of twin shaft grinding with higher flow capabilities and screw screening systems. Here’s a rundown on the past and present state of the art in wastewater solids reduction.

  5. Improving Dissolved Air Quality With The AirWhip™ DAF Pump 7/23/2024

    Learn how incorporating the AirWhip™ pump technology into DAF systems can achieve efficient flotation, improving the quality of the dissolved air and allowing maximum adhesion to the floc particles.

  6. Durable Screen Line Expanded To Meet Vertical And High-Flow Applications 11/18/2020

    Water and wastewater plant operators often encounter challenging screening situations that aren’t well served by conventional products. This includes deep channel applications, where space is very limited, as well as high-flow applications. To address these growing demands, Parkson recently expanded its Aqua Caiman® line to include the Aqua Caiman® Vertical and Aqua Caiman® HD.

  7. HST™ Turbocompressor For Sky-High Savings In Wastewater Treatment 4/1/2020

    The town of Fraser, Colorado, USA, with an annual mean temperature of 32.5°F is the coldest town in the lower 48 states and gets frost year-round. At an elevation of 8’574 feet, it is also the highest location for Sulzer’s HST 20 turbocompressor in the world. The Fraser WWTP high-speed blower upgrade was completed in early 2019, replacing older centrifugal blowers, which were loud and costly to operate.

  8. HeadCell Project Wins 2018 DBIA Award of Excellence 2/5/2021

    Each year the Design Build Institute of America (DBIA) selects the best large-scale Design-Build projects in the United States in a wide variety of infrastructure categories. Atlanta, Georgia’s R.M. Clayton Water Reclamation Facility (WRF) headworks upgrade project featuring HeadCell® grit separation won the coveted 2018 DBIA National Excellence Award in the Water and Wastewater category. Read the full case story to learn more.

  9. Successful Flygt 4220 Mixer Trial Wins Over Hesitant Utility 2/2/2023

    Explore how a wastewater treatment plant realized significant energy savings and increased performance with adaptive mixer technology.
