Unique Mixing Chamber High DO | No Dead Zone Horizontal Scouring | QXB/FQXB Submersible Centrifugal Aerator
The QXB Centrifugal Submersible Aerator and FQXB Floating Submersible Centrifugal Aerator are engineered for wastewater biochemical treatment and large-area water oxygenation. Featuring a direct-drive motor and impeller design, the equipment creates centrifugal force that displaces water to form a low-pressure vacuum zone, automatically drawing in atmospheric air. The innovative gas-mixing chamber shears air into micro-bubbles for exceptional oxygen dissolution rates, while centrifugal force expels powerful horizontal aeration flow to eliminate mixing dead zones.

Key Applications
Core Biochemical Wastewater Treatment: Deployed in aeration tanks and aerated grit chambers of sewage treatment plants. Provides efficient oxygenation and mixing for sewage-sludge mixtures, creating optimal conditions for aerobic microbes during biochemical treatment processes.
Large-Area Natural Water Oxygenation: The FQXB floating model is ideal for oxidation ponds, rivers, and large aquaculture fish ponds. Serving dual mixing and aeration functions, it adapts to fluctuating water levels and reduces infrastructure costs compared to traditional aeration systems.
Frequently Asked Questions
How does this submersible equipment prevent water ingress and seal failures during prolonged continuous operation?
The QXB series incorporates multiple mechanical defense layers including heavy-load bearings with oil-bath shaft seals. During operation, air drawn into the impeller chamber creates a pneumatic barrier that prevents water contact with mechanical seals, ensuring reliable 24-hour continuous operation for long-term performance.
What is the solution if the facility cannot stop its ongoing process for installation or lacks a flat underwater foundation?
The FQXB Floating Submersible Centrifugal Aerator provides the ideal solution for complex sites. Integrated with a fiberglass float for self-weight floating positioning, it enables easy deployment and relocation on water surfaces without interrupting treatment processes. Its self-priming function requires no external air source, and underwater operation eliminates ground-level noise pollution.
