The Lanjiang QXB5.5 is a robust submersible centrifugal aerator designed for medium to large municipal and industrial wastewater treatment applications. This 5.5 kW unit provides substantial oxygenation power for demanding treatment processes including activated sludge systems, aeration channels, and industrial effluent treatment.
Technical Specifications
Power Rating:5.5 kW
Air Flow Rate:85 m³/h
Aeration Capacity:5.3 kgO₂/h
Service Diameter:Up to 8.6 metres
Max Operating Depth:6 metres
Operating Principle
Operating on the principle of centrifugal self-aspiration, the QXB5.5 draws atmospheric air through its intake pipe and mixes it with ambient water in a purpose-built chamber. The high-speed rotating impeller shears the air into micro-bubbles, maximizing the gas-liquid interfacial area for rapid oxygen dissolution. The aerated mixture is then discharged horizontally at high velocity, creating a strong convective flow that maintains complete mixing throughout the basin—effectively combining aeration and mixing functions in a single unit.
Construction Features
IP68-rated submersible motor
Class F insulation system
Heavy-duty bearings with ≥100,000 hour design life
Oil-bath mechanical seal system for leak-free continuous operation
Industrial-grade construction for demanding environments
