MEGA BUBBLE generators are fixed in bottom or liquid tanks. 
The principle of operation is that a blower placed outside the tank delivers air into the mega bubble generator. 
T The pressurized air pushes the water inside the accumulator body of the generator and creates an air pocket. 
T Periodically this air pocket is ejected outside as a large bubble and liquid backfills into the accumulator, starting the cycle again. The period of bubble release is very short (< 1/16 second ), which initiates torridal movement with a size of about 3 ft in diameter moving up at high velocity creating a suction effect below it inducing circulation of liquid in the entire tank.
