Floating Low Speed Surface Aerator

Efficient Oxygen Transfer. Proven Reliability. Built for Harsh Environments.

Our Floating Low Speed Surface Aerator is designed for wastewater treatment applications where efficient aeration and robust construction are critical. It is ideal for use in oxidation ditches, lagoons, and activated sludge processes where additional aeration is required, but there is no available platform for a fixed unit

Ideal for municipal and industrial wastewater treatment facilities aiming to enhance treatment efficiency and reduce operational costs.

Typical applications for the Floating Low Speed Surface Aerator are:

  • Municipal & industrial wastewater treatment plants
  • Aerated lagoons & oxidation ponds
  • Nutrient removal & sludge stabilization
