Specifications
SKAWT Submersible aerator
The self-priming Submersible aerators also called as immersible aerator ,can be used for oxygenating and mixing in sewage water treatment. It integrates the pump, Air-blower, Gas-liquid mixers as one. It can be operated under the water, which can be placed in the bottom of the sewage aeration pool, or be fixed on the floating body.
Applications
The Submersible aerator is applicated to many links of the sewage water treatment, such as Pre-gas supply, Activated Sludge Treatment, Stability Sludge Treatment, gas floats, neutralize, Ozone treatment, Oxidized pond, liquid-mix .But the main application is highly effective of supplying the oxygen and mixing the medium transported.
Operating principle
The submersible aerator is composed of Star- type impeller and Stator and air pipe. The rotation of impeller makes the stator vacuum, and suck the air through the pipe, the water and the air enter into the impeller through the Entry between the rotor and stator, they are fully mixed in the impeller, the gas is dispersed into a small bubble of about 100 microns in diameter, that forms a huge area of the gas-liquid .It achieves the highly effective of transporting and mixing oxygen.
Design and features of submersible aerator
1. Automatic sucks the air under the water, saving the gas-supply equipment, antifreeze, lower noise.
2. Bigger touch area of liquid and gas, higher coefficient of oxygen utilization ,better sewage treatment effect , and effect of energy saving is significant .
3. Good efficient of mixture, without any settling in the bottom of sewage pool.
4. Easy installation and maintenance, and difficult to be blocked up.
