HURRICANE® Submersible Aerator/Mixer

The Hurricane air diffuser’s updated design simplifies assembly with fewer parts and increases performance life with only one moving mechanism. The self-contained system ensures an inexpensive installation process and requires no additional pumps, mounting platforms, or compressors. The rotating impeller draws atmospheric air into the inlet piping, combining it with the water and expelling it at high velocity.

Reaching depths of 24 feet, the Hurricane aerator delivers high oxygen transfer rates and considerable energy savings. The Hurricane operates at greater depths with blower assist. Specially designed impellers allow operation as either a mixer or an aerator/mixer by valving off the air inlet pipe or by changing the water depth in the basin – perfect for sequence batch reactor applications.

Features of the Hurricane Submersible Aerator

Fluence manufactures the entire impeller and stator from one piece of 17-4 stainless steel hardened to Rockwell 45 HRC, creating greater abrasion resistance. Positioned within the stator, the impeller is balanced for minimal vibration and maximum chopping action to crush solids. The stator can be switched out without having to replace the entire aerator assembly, making upgrades simple.

With 14 model sizes ranging from 5 to 100 hp (3.75-75 kW), the Hurricane aerator/mixer fits multiple applications. You can also choose fixed or removable mounting options. The aerator base features large, extended legs for stable, wide-radius support. These adjustable legs make it easy to level the equipment on most basin floors, and their vibration-dampening feet help prevent “walking.”

The Hurricane aerator also features:

• Corrosion- and UV-resistant stainless-steel construction throughout
• Stainless steel air inlet piping
• One moving part
• Multiple tubes adapted to rectangular or circular basins and provide uniform air distribution for full-floor coverage
• Mixer or aerator/mixer functionality by valving off the air inlet pipe or by changing the water depth in the basin
• Customized air diffuser tubes for most efficient aeration mixing
• Diffuser tubes adapted to rectangular or circular basins and provide uniform air distribution for full-floor coverage

How the Hurricane Aerator/Mixer Works

We’ve designed the Hurricane aerator with a minimum of moving parts for reliable oxygen transfer and basin mixing. Deployed at the bottom of a tank or basin, the integrated submersible electric motor rotates a solid 17-4 stainless steel impeller to generate a low-pressure zone around the impeller blade tips.

The pressure differential created between this low-pressure zone at the bottom of the tank and the air at the wastewater’s surface forces air down a stainless-steel inlet tube into the Hurricane’s central stator assembly. The close impeller tolerance and stator assembly are used to soften grit and other solids in the wastewater, making the Hurricane ideal in high-solid environments.

In the stator, surface air and water mix through the rotation of the impeller and the turbulence it creates. High oxygen transfer also occurs in the stator assembly due to the break-up of air into tiny bubbles. The high surface area-to-volume ratio of these little bubbles promotes high oxygen transfer into the wastewater, further enhanced by the high distortion of bubble surfaces by the turbulence of the stator.

The Hurricane expels the oxygen-enriched combination of air and water at a high velocity from the central stator assembly through radial diffuser tubes to deliver oxygen throughout the basin floor. As the air bubbles rise from the bottom of the tank, further oxygen transfer takes place until the bubble release pattern thoroughly mixes in the reservoir with intense agitation.

The completely submerged operation of the Hurricane aerator/mixer eliminates splashing, minimizes the generation of hazardous aerosols, and promotes stable biological treatment even in the coldest climates.
