Product Usage
The QLP submersible centrifugal aerator is used in the aeration tank and aeration sedimentation tank of sewage treatment plants to oxygenate and mix the mixed liquid of sewage sludge, as well as for biochemical treatment of sewage or oxygenation of aquaculture ponds. The intake volume is 35-320m3/h, the oxygenation capacity is 1.8-24kgQ2/h, and the motor power is 1.5-22kw.

Product Principle
The structure of QLP submersible aerator is a direct connection type, please refer to the legend.
The rotating impeller generates a centrifugal force in the water, which creates a negative pressure zone around the impeller. Air is then drawn in through the intake pipe and mixed with the mixture in the mixing disc. This good and uniform mixture is then automatically discharged from the outlet.
This process includes the following aspects:
The mixing of air and water in the mixing tray produces a gas-liquid mixing effect, and the gas-liquid mixed flow discharged from the outlet forms circulation and convection; The oxygen in a large number of air molecules achieves a very high oxygen absorption efficiency for high-speed motion.

Product Model

Product Features
1. High oxidation dissolution rate, large proportion of small bubbles, high oxygenation efficiency, and large oxygenation area;
2. There is no dead zone in the pool, and the horizontal exposure airflow carrying bubbles can completely flush every corner of the pool bottom;
3. The bearings with simple and compact structure, long unit life, and the ability to withstand high loads, as well as the use of oil bath rotary suction sealing shaft and air suction impeller cavity to prevent water from coming into contact with the seals during operation, will ensure that the aerator can work continuously for 24 hours and operate without faults for a long time;
4. Save engineering investment, no need to provide gas source, eliminate blower, easy installation, and low noise.
