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.
When the Jacksonville, Florida Naval Air Station needed to increase oxygen in their aeration basins, they turned to RWL Water. Five submersible HURRICANE aerators provide bottom-up mixing, drawing surface air and dispersing it in a 360-degree pattern near the basin floor. Long bubble hang time results in excellent oxygen transfer, and ensures excellent BOD and ammonia removal, treating flows up to 3 MGD.
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.
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.
The Twister aerator provides outstanding mixing and durability for wastewater treatment and supplemental aeration. The slow-moving rotating turbine’s specially designed vanes create a strong pumping force that pulls water up from the basin. This provides an ideal air-to-water interface, creates high oxygen transfer, and optimizes the wastewater treatment process.
The HURRICANE® Submersible Aerator/Mixer offers unmatched ruggedness, quality and serviceability. This 360° radially mixing system incorporates new, unique air diffusers designed for high oxygenating efficiency and thorough mixing over a wide area.(Learn more about our full line of aerators and aeration equipment.)
The Water Champ® FX Chemical Induction System from Evoqua has set the benchmark in chemical feed and disinfection with its innovative design and versatile applications for chlorination, dechlorination, chloramines, pH adjustment and rapid mix. The system provides superior mixing intensity maximizing chemical reaction while using less energy. Independent third party testing has proven that a Water Champ system can provide up to 40% better power to flow-rate ratios compared to other induction mixers or conventional methods.
DO2E Aerator / Mixers are high-efficiency all welded, heavy-duty PVC devices that are unique in several ways. DO2E’s patented products are designed to pull water from significant depths for aeration and mixing. By operating with low-pressure (<1.85 P.S.I.) high-volume airflow, these devices maximize energy efficiency. Our patented products are scalable and multi voltage.
Otterbine’s 1/2HP Fractional Series Aerating Fountain and Mixer line includes 4 spray patterns and a horizontal mixer – the only unit like it on the market today!
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.
RWL Water is driven to deploy innovative and cost-effective global water solutions solving water challenges worldwide with expertise in desalination, water, wastewater, waste-to-energy, recover and reuse, and food and beverage processing solutions. Learn more here.
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.
