With more than 700 installations, Vaughan's Rotamix System is today's most cost-effective means of mechanical hydraulic mixing. Consisting of an engineered arrangement of floor-mounted nozzles, fed by a Vaughan Chopper Pump, and using custom software, each application is analyzed by Vaughan's experts to achieve the desired mixing effect. The Rotamix system may be applied in circular, rectangular, or oval tanks and basins, as well as other unique process configurations, such as egg-shaped digesters, CSO tunnels, and pump stations.
Upgrade To Diffused Aeration Results In Significant Energy Savings By Sanitaire -- A Xylem Brand
After 35 years of use, the fiberglass jet aeration manifolds in the Western Regional Water Reclamation Plant (Dayton, OH) 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.
Gas Transfer Using The Patented Dif-Jet System By Gary L. Rogers, Ph.D., P.E., Applied Aquatic Engineering, LLC
This paper discusses gas transfer theory and key factors of the process along with sample applications using the Dif-Jet, including transfer of CO2 gas for pH neutralization of wastewater, for aeration and oxygenation, and for disinfection using ozone.
Aeration System Helps Cheese Production Plant Solve Nitrogen Discharge Challenge By KLa Systems
A gourmet cheese, whey protein, and lactose production facility located in the midwest had been utilizing a land application system for effluent discharge for more than 40 years. As the gourmet cheese products gained in popularity along with the growth in demand for food grade whey protein and lactose, the plant grew to a scale where the land application system could no longer achieve compliance with the strict ground water standards for nitrates.
How To Remove FOG Deposits And Prevent Sewer Overflow By DO2E
Fats, oils, and grease (FOG) deposits present a problem for the wastewater industry, as they create sewer lines blockages that lead to overflow. Digester systems can successfully remove these deposits with the latest environmentally friendly technology by breaking them down into microparticulates.
Eliminating Sludge Islands In Your Wastewater Lagoon By Jim Dartez, RELIANT Water Technologies
Old municipal and industrial wastewater lagoons have the tendency to build islands of sludge at various locations around the lagoon. It is most common for older lagoons to build such islands wherever wastewater enters the lagoons.

3 Tips For Utilities On Effective Consumer Outreach
Common understanding of the role water and wastewater utilities play in our daily lives is essential for the successful and sustainable management of water and financial resources. No one knows this better than drought-plagued California. Here are a few tips for teaching the value of water, inspired by a state that’s running out of it.
To comply with new EPA rules and handle additional flow, the City of St. Charles, MO, 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.
Especially for rotating equipment, maintenance plays a significant role in the selection process. The Aqua-Jet aerator offers a heavy-duty vibration-limiting design for equalization basins, batch reactor processes, sludge holding, and long residence time processes in cold climates.
This know-how brochure gives an overview of how KSB submersible mixers of the small blade (Amamix) and large blade (Amaprop) variety have been utilized in the past, and which applications are possible.
