TWISTER Theory Of Operation

All TWISTER aerators consist of a motor mounted to a gear reducer and an extended shaft. A specially designed rotor is attached to the bottom of the extended shaft. The aerator is positioned so the rotor is partially submerged in the wastewater when activated the TWISTER aerator turns at a slow speed (typically 40 to 100 rpm). Specially designed fins on the rotor then pump massive amounts of water into the air in a fine spray. These very small droplets
Create a 360-degree circular pattern.

High transfer of oxygen results from the large surface area to volume ratio of the water droplet and its long exposure time in the air during its spray trajectory. Oxygen transfer is further enhanced by taking advantage of the oxygen transfer gradient of O₂ deficient water at the bottom of the basin by pumping it up and exposing it to air above the water surface to promote faster mass transfer from ambient air to water droplet.

The deep pumping action of the TWISTER aerator generates effective localized mixing to optimize many wastewater treatment processes. The TWISTER aerator is ideal for many industrial treatment processes requiring fast and efficient oxygen transfer such as pulp & paper, food processing and others.
