Frequently Asked Questions (FAQ)

Q1: What is the core working principle of a submersible agitator aerator?

A: The equipment delivers compressed air through an external blower, which is then introduced into the high-speed rotating impeller chamber through an internal air duct. The impeller shears and crushes the airflow into tiny bubbles, and uses strong underwater turbulence to achieve three-phase mixing of water, gas, and sludge. This promotes efficient aeration and oxygenation while promoting water circulation, preventing sedimentation of activated sludge and ensuring the continuous and stable progress of aerobic biochemical reactions.

Q2: What are the advantages of this equipment compared to traditional microporous aerators?

A: Traditional microporous aerators are prone to clogging by sludge and require regular replacement of the aeration disc. Water supply must be stopped during maintenance; The submersible agitator aerator has no microporous structure, never clogs, and has mixing function. It does not require frequent maintenance and can be retrofitted without stopping water. The deep water oxygenation effect is better and the long-term operation and maintenance cost is lower.
