High Efficiency Submersible Centrifugal Aerator for Wastewater Treatment with No Dead Zones and Durable Design

QXB Submersible Centrifugal Aerator is designed for wastewater treatment plant aeration tanks and grit chambers, providing efficient oxygenation, mixing, biochemical treatment, and aquaculture aeration.

• High Efficiency: Unique chamber design creates abundant microbubbles for superior oxygen transfer and wide coverage
• No Dead Zones: Horizontal aerated flow scours the tank bottom entirely, eliminating blind spots
• Durable Design: Heavy-duty bearings and air-protected oil-bath seal ensure 24/7 continuous, trouble-free operation
• Quiet Operation: Submerged operation minimizes noise, with optional air intake silencer available

A direct-drive impeller generates centrifugal force to create a vacuum, simultaneously drawing in air and water. These blend in the mixing chamber and are rapidly discharged as a uniform mixture.

The powerful jet shears air into microbubbles. Their slow ascent and strong continuous convection maximize oxygen dissolution, offering significantly higher power and oxygen transfer efficiency than conventional aerators.

• Easy Installation: Positioned by its own weight; can be deployed without stopping plant operations
• Self-Aspirating: Compact design needs no external air source
• Quiet & Compact: Submerged operation saves space and reduces noise
• Cost-Saving: Can be used directly in oxidation ditches, cutting infrastructure costs
• Dual-Function: An independent unit offering simultaneous aeration and mixing
• Customizable Base: The chassis can be tailored to specific user needs

Consists of a submersible pump, mixing chamber, base, air intake pipe, and silencer.

The rotating impeller drives high-speed water into the mixing chamber, creating negative pressure. This draws air from the above-water intake pipe to mix with the water. The mixture is then discharged peripherally to efficiently oxygenate the liquid.
