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.
The Madison Metropolitan Sewerage District (MMSD) manages regional wastewater service for the Madison, Wisconsin area, providing wastewater collection and treatment for 43 municipal customers including cities, villages, and utility and sanitary districts.
The Chicago area is served by a combined sewer network that carries both raw sewage and storm water.
Wastewater treatment lagoons were originally facultative in design — shallow, single and multi-cell lagoon systems that counted on wind, sunlight, anaerobic bacteria, and time for the digestion of the organic components of the wastewater.
The City of Reno, NV, has long battled the buildup of fats, oils, and grease in the wetwells of wastewater lift stations in the valleys within this high desert city. Recently, the city set out to address the problem and reduce the associated costs.
The Cypress Creek WWTP in Florence, AL, uses an extended aeration activated sludge process with a design capacity of 20 million gallons per day (MGD). Cypress Creek serves mostly residential customers, but about 15 percent of its influent comes from industrial sources, and their discharge to the plant contains large amounts of fats, oils, and grease (FOG).
A WWTP facility in Indiana serves a six-square-mile area, and has historically experienced pronounced peak flows caused by nearly one-fourth of its collection system consisting of combined storm water and sanitary sewer lines.
For almost 50 years, CPS Energy of San Antonio has drawn water from the San Antonio River to recharge two man-made lakes that provide cooling water for their power plants.
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.
High Oxygenation and 360-Degree Radial Mixing.
The Hurricane submersible aerator’s 360-degree radial mixing system incorporates new, unique air diffusers for high oxygenating efficiency and thorough mixing over a wide area.
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.
In this video, Parkson discusses the process of biologically treating wastewater in a batch mode and what differentiates Parkson's SBR from others.
The Water Champ® FX System improves open-channel disinfection process by replacing conventional mixing and diffusers with an easy, fast and effective chemical induction system. Constructed for the highest level of durability and performance, it is compatible with chlorine gas, sodium hypochlorite (bleach), ammonia, sulfur dioxide or bisulfite.
The Flygt 4320 allows you to adjust for today’s flows and loadings, quickly change to meet seasonal fluctuations, and be prepared for future increases – all without wasting energy.
The Reliant Lagoon Master Water-Moving Aeration System (formerly Model WQA) is not just an aerator, but it is a water-mover with the ability to deliver large amounts of dissolved oxygen (DO) using a minimum of energy.
This video demonstrates how Vaughan Company's Small Tank Mixing Assembly can be utilized to mix only the bottom portion of a tank while leaving the top in a non-turbulent state.
Introducing Vaughan Company's new Small Tank Mixing system, this product is meant for smaller applications where there is a need to create a homogenized slurry. This is perfect for getting the most out of your F.O.G. (Fats, Oils, and Greases) application. Part 2 illustrates how this product can be utilized within a Salt Water Disposal application.
