Wastewater Case Studies and Whitepapers

  1. High-Capacity Washer Compactors Compress More Debris, Save More Money 4/17/2023

    Duperon’s new high-capacity washer compactor was designed to tackle the most difficult challenges while reducing overall operating costs.

  2. Upgrade To Diffused Aeration Results In Significant Energy Savings 12/12/2013

    After 35 years of use,  the fiberglass jet aeration manifolds in the Western Regional Water Reclamation Plant (Dayton, Ohio) had deteriorated, rendering four of eight wastewater aeration tanks inoperable. Managers recognized an opportunity to utilize a fine bubble diffused aeration system that eliminated the need for the pumps. The result: higher oxygen-transfer efficiency and reduced power costs to operate the system.

  3. Victor Valley Recovers From Mojave Desert Environmental Catastrophe 1/30/2020

    Pushed beyond the limits of its banks, the Mojave River gushed at more than 36-cubic-feet-per-second in the Upper Mojave Narrows. It was an environmental catastrophe and needed attention immediately.

  4. N-Technology Impeller Pumps Eliminate FOG Buildup At Resort And Casino 3/19/2015

    The successful addition of new restaurants and clubs at a resort and casino in Upstate NY brought with them a flow of fats, oil and grease (FOG), which gelled into a floating blanket atop the main station’s wet well, where the sewage flows converge from the network of smaller stations throughout the property boundaries.

  5. Renting Or Buying Aeration Equipment: A Decision Framework 9/18/2026

    Project duration, available capital, and operational risk can help wastewater facilities determine whether renting or purchasing an aeration blower is the better fit.

  6. City Of Dartmouth Reduces Polymer Usage And Improves Dry Solids With PolyBlend® Polymer Preparation Systems 8/10/2016

    The City of Dartmouth, MA, Water Pollution Control Division is responsible for operating the town’s 3 million gallon per day wastewater treatment facility, a testing laboratory, a composting site, a sludge.

  7. Revolutionizing Pumping Station Control 1/19/2021

    Read about an award-winning project that was able to effectively improve performance and control of sewage pumping stations.

  8. The Better Business Case For Advanced Turbo Blowers

    Wastewater treatment plant managers face multiple hurdles to achieving optimal dissolved oxygen levels in aeration basins at the lowest possible energy cost. The upside is that turbo blowers have evolved into a highly efficient, viable option that can be plugged into the equation.

  9. On-Site Sludge Digestion: Aerators And Aerobic Mixers 2/14/2014

    A brief introduction into sludge digestion by means of aerators and aerobic mixers that are located on-site is provided. Rationale for treating on-site as well, as is a discussion of sludge characteristics and how they may be addressed are similarly considered. This is an introduction only and will be followed by development of the topic in more detail in later papers. By Dr. J.H. Wakefield, consulting scientist/engineer

  10. Disc Aerators Replace Brush Aerators, Increasing Capacity And Performance 1/15/2014

    To comply with new EPA rules and handle additional flow, the City of St. Charles Missouri WWTP required a capacity increase, and the landlocked plant needed a solution that would fit within its existing footprint. Brush aerators and boat clarifiers were replaced with 12 VLR-mounted disc aerators to fulfill the oxygen requirement while allowing for the treatment of higher organic loading. The solution provided increased nutrient-removal capacity and improved efficiency without increasing tank volume.
