When bodies of water become stagnant or polluted with nutrients, it can lead to odors and algal blooms. Aeration is a proven solution.

By distributing oxygen through bodies of water, aeration can restore them to a healthy balance

Aeration is the process by which air is introduced into water or another substance. Introducing dissolved oxygen into a body of water can have a number of benefits, including odor and algae control. Wastewater treatment plants, industrial operations, and bodies of water in recreational areas can all benefit from the increased oxygen, which promotes the health of aquatic life and feeds the aerobic bacteria that break down nutrients that promote overgrowth of algae.

Aeration in Wastewater Treatment

In wastewater treatment lagoons, it may seem that odors are unavoidable, but in fact they’re an indicator of something wrong in the treatment process. The most direct way to correct a system is to introduce more dissolved oxygen with aerators, feeding beneficial bacteria. Aerators also simultaneously mix the lagoon, which helps reduce sludge at the bottom, where odor-causing anaerobic bacteria thrive.

It also is important to have enough aeration power to react to seasonal variation. Bacteria are more active in warm weather, so more oxygen is necessary to support the burgeoning aerobic bacterial population.

Aeration in Bodies of Water

All-Season Submersible Aerator

The self-contained AQUA TORNADO® injects air into water at high speed, and is well-suited for ponds and reservoirs from 4 to 15 feet deep.

Aeration’s benefits aren’t limited to wastewater treatment. Lakes, ponds, and other bodies like golf course water features also can be affected by high nutrient loads, anoxic zones, algal blooms, and fish kills. These can be caused by fertilizer runoff, and contamination by human or animal waste.

As in wastewater lagoons, still waters can become stagnant and stratify into layers of different temperatures, blocking the movement of dissolved oxygen to lower depths and producing odor. Aeration can disrupt these layers so oxygen can reach the entire volume of water.

The Fluence TORNADO® line of aerators is well-suited to a wide range of applications, from use in activated sludge sewage plants to protecting the aesthetics of recreational water bodies. TORNADO® can help keep odors down and water clear without chemicals.

TORNADO® aerators are available in a range of models, including:

  • TORNADO® self-aspirating aerator, which draws air from the surface and injects it beneath the surface, is available in sizes from 2 to 100 horsepower (1.5 to 75 kW).
  • TORNADO® blower-assisted aerator, which uses a blower to force more air down the inlet and into the wastewater, is used for applications requiring a higher level of oxygenation. It’s available in sizes from 2 to 100 horsepower (1.5-75 kW).
  • AQUA TORNADO®, a model designed for fresh water, requires no additional pumps, blowers, or mounting platforms and is effective in all seasons. It’s available in 2- and 3-horsepower versions, and it even has an artificial rock covering available to protect aesthetics.

A 100% American stainless-steel option is available to meet purchasing requirements.

In Minneapolis, Minnesota, Fluence manufactures seven lines of aerators using top-quality materials, engineering, and workmanship for a wide range of applications and with minimal maintenance.
