TORNADO® Sub-Surface Aerators / Mixers Product Information

The TORNADO® family of Sub-Surface Aerators delivers excellent oxygen transfer and high mixing efficiency to a wide range of wastewater treatment processes in any climate. From extended aeration to activated sludge to lagoons and oxidation ditch applications, the TORNADO® aerator's rugged but efficient design maximizes treatment performance while minimizing energy consumption. This unique product mixes and aerates all or part of a basin.

The TORNADO® aerator is designed with a large diameter stationary draft tube with unrestricted air inlet to convert the least amount of energy into the maximum amount or aeration and mixing capacity. All aeration and mixing is delivered below the water surface to eliminate odors from splashing or spraying. No harmful aerosols filled with bacteria are generated keeping the treatment process safe and secure. The self-heating design of the TORNADO® aerators makes it ideal for year-round operation in cold weather climates. Needing no pumps or other accessories, the TORNADO® aerators provide a self-contained system that saves money in installation and operating costs. Angle adjustments allow optimization of horizontal mixing velocities, mixing depths, and bubble-hang time. TORNADO® aerators are unmatched with all stainless steel construction providing excellent corrosion and UV resistance even in the toughest wastewater. With a huge installed base, with thousands of units running throughout the world, the TORNADO® Family of Horizontal Surface Aerators is the most cost effective way to improve the performance of your waste water treatment operation.

The TORNADO® aerator is available in three versions:

Self Aspirating Aerator - aerates on its own by aspirating air from the surface and injecting it beneath the surface. Available in sizes from 2 to 100 Hp (1.5 to 75 kw).

Blower Assisted TORNADO® Aerator - adds a separate small blower to the Self Aspirating TORNADO® aerator to force even more air down the inlet and into the wastewater. This process produces high oxygen transfer and mixing, up to 10% better than self-aspirating models. Available in sizes from 2 to 100 Hp (1.5 to 75kW).
