Fast, flexible and energy efficient aeration for SBR, MBR and lagoon applications.
The Spaans Babcock floating O₂Rotor brush aerators provide a powerful and adaptable solution for biological wastewater treatment.

Designed for use in sequencing batch reactors (SBRs), membrane bioreactor (MBR) systems, carousel basins, lagoons, and even open water oxygen boosting, these units deliver high performance aeration wherever and whenever it is needed.

Built on a robust floating assembly with two parallel pontoons supporting a purpose built platform, the system can be deployed rapidly, ideal for emergency situations, plant upgrades, or sudden drops in dissolved oxygen.

O₂Rotor Floating Brush Aerators: fast, flexible, energy-efficient aeration for wastewater and emergency applications.

Why Choose O₂Rotor Floating Brush Aerators?

Optimised biological performance

• High oxygen transfer efficiency to maximise treatment output while minimising energy use
• Enhanced mixing for stable biological processes and consistent effluent quality
• Uniform flow distribution to prevent dead zones and sedimentation

Low operational cost

• Energy efficient design reduces long term operating expenses
• Low maintenance requirements minimise downtime and service interventions
• Extended service life protects your investment

Flexible deployment

• Rapid installation and relocation
• Ideal for temporary, seasonal, or emergency aeration needs
• Provides additional kinetic energy (flow)

Where Floating O₂Rotor Aerators Excel

• Carousel basins
• Lagoon treatment systems
• Sequencing batch reactors (SBR)
• Membrane bioreactor (MBR) installations
• Oxygen boosting in rivers or lakes

Perfect for Critical Situations

Emergency aeration

• When equipment fails or oxygen demand spikes unexpectedly, floating O₂Rotors keep your biology alive and stable

Plant retrofitting

• Maintain full operation while refurbishing existing aeration systems (no need for plant shutdowns)

Sudden oxygen depletion

• Deploy additional aeration instantly to restore DO levels and protect activated sludge health.
