Product Description

Products Description

Submersible Jet Aerator

The submersible jet aerator is used for oxygenating and mixing the mixture of sewage sludge in aeration tanks and aeration grit chambers of sewage treatment plants, as well as biochemical treatment of sewage or oxygenation of breeding ponds. The intake air volume is 42~400m3/h, and the oxygen-enhancing capacity is 2.3~24kgO2/h.The rated power is 2.2~22kW.

Data to be provided for model selection:
1. Oxygenation capacity (kgO2/h)
2. The shape, size and water depth of the aeration tank (m)
3. The water quality of the aeration tank (such as temperature, BOD5, COD, etc.).

Working Principle

The water flow generated by the submersible pump passes through the nozzle to form a high-speed water flow, which forms around the nozzle negative pressure sucks in air. After mixing with the water flow in the mixing chamber, a water-air mixed flow is generated in the trumpet-shaped diffuser tube, which is ejected at a high speed, and the water flow with many bubbles is vortexed and stirred in the water with a large area and depth to complete the aeration. And its shaft power does not change with the change of the submerged depth, and the intake air volume can be adjusted. Because of this, jet aerators can be used in tanks with large changes in water level.

Features

The aerator is composed of a submersible motor and a jet pump, so that the water body can be stirred and oxygenated at the same time, so that a higher oxidation absorption rate can be obtained, and the impeller has the advantage of no blockage;
The powerful unidirectional liquid flow results in effective convection circulation, and the motor load changes little with water, making it easy to install.
