Wastewater Case Studies and Whitepapers

  1. Sonoma County Improves Sludge Handling With Screw Press Pump Technology 12/7/2015

    When California’s Sonoma County Water Agency (SCWA) wanted to improve its sludge solids dewatering as part of a major sludge handling upgrade, they were seeking an alternative to outdated sludge belt press/conveyor technology.

  2. Dry Pit Submersibles Lower Costs And Eliminate Unscheduled Maintenance 10/2/2015

    A utilities department was experiencing frequent unscheduled maintenance visits and corresponding unbudgeted repair bills for the pumps at the township’s main pump station.

  3. Refinery Expands Production While Meeting Discharge Standards Quality 8/5/2016

    Petron Bataan Refinery wanted to expand production to process 180 thousand barrels of crude oil per day while changing its feedstock from Arab Light to less costly heavy and sour crudes.

  4. Navigating The Partial-Pipe Flow Challenge 10/10/2019

    One of the most perplexing challenges that wastewater plant operators face is the need to measure the various sources of influent. For closed-pipe systems, the use of traditional flow devices requires intensive and expensive engineering to keep the pipe full at the point of measurement. The good news is that there is an emerging solution that measures flow in a less-than-full pipe.

  5. Repair Of Major Damage To High Density Polyethylene Wastewater Pipeline 8/13/2018

    Leprino Foods, the world's largest mozzarella cheese producer, operates two plants that share one wastewater pipeline – a 16” SDR11 High Density Polyethylene Pipeline (operating at approximately 160 PSI). During dirt work an “auger” hit the wastewater pipeline and drilled an 8” diameter hole in the line. Leprino needed immediate access to a repair fitting for this line.

  6. Wastewater Treatment Double-Play Game Winner 4/15/2019

    While aeration and digester wastewater treatment systems are fundamentally different, they share common challenges when it comes to accurate air/gas flow measurement. Flow meters need to operate over a wide flow range, fluctuating from very high to low rates.

  7. Pre-Filtration Is Essential To Protect Your Membranes 12/15/2016

    Any Reverse Osmosis System is only as good as the Pre-filtration System protecting it.  Pre-filtration is no place to scrimp when it comes to sizing, quality, efficiency and performance. 

  8. 5 Essential Safety Devices On Aeration Blowers: What You Need To Know. 6/17/2024

    Explore some common safety devices used in aeration blowers, how they work, the potential consequences of their failure, and best practices for inspection and maintenance.

  9. A Multi-Barrier Approach To Complex Water And Wastewater Contaminant Removal 2/25/2021

    With the issue of water safety in the headlines, even non-water professionals are familiar with common contaminants like lead and arsenic – but how can we address these public health hazards?

  10. 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.
