Product Description

1,function:

QSB type submersible jet flow aeration used in sewage treatment plant aeration pond, aeration grit chamber, make the sewage and sludge mixed liquor oxygenate mix , biological treatment sewage or Breeding pond increasing oxygen , air inflow is 10-400m³/h. increase oxygen capacity is 0.37-24kg/h, motor power is 0.75-22kw,can separate use or combine use.

2,Principle

The water flow produce by submersible pump form high speed water flow by nozzle, it will form negative pressure and inhale air around nozzle, blend in mixing chamber and water flow, it will produce water and air mixed flow in diffusion tube, high speed eject out, carrying many bubble in water flow in larger area and depth water area vortex stir finished aeration, and the air inflow can be adjust.

3,Characteristic

Structure compact, small area occupy, convenient installation; except air inlet, the other parts submerge into water, small noise, inhale more air, produce more thin bubble, dissolved oxygen rate; no need supply air source, save air blower, small project investment; adopt international advanced submersible sewage pump design technique, impeller flow pass adopt non Clogging, operation safe and reliable.
