WASTEWATER MIXING WHITE PAPERS AND CASE STUDIES
A More Reliable, More Efficient Aerator – Tomball, TX WWTP
In 2013, operators of the Tomball, Texas Wastewater Treatment Plant were facing increasing maintenance issues with three brush aerators operating in the plant's two-channel oxidation ditch. The aerator failures were threatening to compromise effluent quality and environmental compliance. Tomball needed replacements.

WASTEWATER MIXING PRODUCTS
The JCS Industries Model 4140 VIM-OC Vacuum Induction Mixer is a proven and reliable device that utilizes vacuum to safely and effectively induce both gaseous and aqueous chemicals into open channel water stream applications.
The RW is Sulzer’s standard range of submersible mixers, economical without compromising on reliable design. These compact, versatile submersible mixers are ideal for agitating, blending, mixing, dissolving, and suspension of solids in municipal treatment plants, industry, and agriculture. The RW mixers can easily be fitted to existing guiderails and lifting devices without modification, using our wide range of brackets and adapters.
The submersible mixed-flow column pump type ABS AFLX equipped with an IE3 motor is designed for use where large volumes of process water or wastewater containing solid effluent must be pumped up to moderate heads. Premium Efficiency motors combined with efficient three- to five-blade mixed-flow impellers with low NPSH characteristic impeller design, ensure high reliability and efficiency.
PAX Water Technologies is the leading manufacturer of technologies that improve water quality in storage tanks and in water distribution systems. With an install base of thousands of units worldwide and an average fleet age of over seven years, PAX Mixers™ are the most frequently specified mixing system by consulting engineers and municipal water system operators.
Flygt, the industry leader in municipal wastewater mixing, is proud to raise the standard in high efficiency, low-speed submersible mixers. Flygt 4320’s revolutionary design couples a high efficiency mixer and state-of-the-art motor efficiency, with an integrated variable frequency drive (VFD). The result is a submersible mixer that delivers superior mixing with adjustability and simplicity, for unsurpassed energy savings.
Customers often ask us: “What's the best impeller material?” Unfortunately, there is no standard answer because there is no such thing as standard wastewater. Since there are different types of wastewater, material choice for specific sewage applications is critical for ensuring long pump life.
Vaughan’s Turbo Mixer is a propeller mixer mounted vertically inside an 18” elbow. This mixer has replaced many submersible propeller mixers which have experienced motor or gearbox failure due to fluid inleakage. The Turbo can mix a pit with only one foot of liquid above the floor, something a horizontal shaft submersible mixer cannot do.
Long-lasting performance, and the highest oxygen-transfer rates of any mechanical aeration system on the market.
WASTEWATER MIXING PODCASTS
At the wastewater treatment facility, the biggest energy consumer is almost always the multistage aeration blowers. Replacing these blowers with high speed turbo blowers can save energy but the short-term cost to replace the existing blowers, reroute pipe and set new foundations can make the change a hard sell.
If you’re not familiar with static mixing and heat transfer, it’s about time for a lesson.
