Surface Aerator

The Biogest CROWN (Biogest GmbH, Germany) is a high-power floating surface aerator specially designed for SBR (Sequencing Batch Reactor) technology. CROWN creates intense surface turbulence, efficiently dissolving oxygen while mixing the entire tank volume.

Key specifications:

• Oxygen transfer rate (SOTR): Up to 2.5 kg O₂/kWh
• Aeration coverage: 10–25 m radius depending on motor power
• Power: 4–75 kW; voltage: 380V/3-phase/50 Hz
• Materials: SS316 rotor, die-cast aluminum body, HDPE floats
• Adjustable submersion depth: Optimize oxygen transfer at varying water levels
