Working principle

The impeller rotating inside the mixing chamber aspirates water through the opening between the motor and the stainless steel body of the unit. By accelerating the water radially 360° through the outlet channels a vacuum is created inside the mixing chamber. This vacuum induces a flow of air into the chamber from above the water level through the aspiration pipe. This aspirated air is mixed with the water to very fine bubbles inside the mixing chamber and then ejected through the outlet channels. The strong density induced flow creates a perfect mixing pattern and oxygen distribution in the tank. Extension channels (option type –C) will optimize oxygen transfer and oxygen distribution.

Applications

  • Homogenisation and equalization tanks
  • SBR plants
  • Activated sludge plants
