QSB Jet Aerators
Submersible aerators are used in aeration tanks and aeration depositing tanks of waste water treatment plants.
QSB Jet Aerators oxygenate the mixture of waste water and sludge and treat the water by biochemistry or oxygenate the breeding pools. Air input: 10-100m3/h, oxygenation capacity:0.35-8.20kgO2/h, motor power: 0,75-7.5kW.
Features
<span style="\"font-family:" verdana,="" geneva,="" sans-serif;\"="">1.Compact structure, small area occupied, easy to install;
2.Except for the air inlet, all the parts are in water and noise level is very low;
3.More air intake, more and small bubble produced and high oxygen dissolution;
4.Not necessary to provide air source, no air blower and engineering cost is fairly low;
5.ABS submersible technology imported from Germany is adopted.
The flow channel of the impeller is adopted of blockless and the operation is safer and more reliable.

Descriptions
Submersible aerators are used in aeration tanks and aeration depositing tanks of waste water treatment plants.
They oxygenate the mixture of waste water and sludge and treat the water by biochemistry or oxygenate the breeding pools
Air input: 10-100m3/h,
oxygenation capacity:0.35-8.20kgO2/h,
motor power: 0,75-7.5kW
STRUCTURE AND OPERATION PRINCIPLE
The submersible aerator is composed of submersible pump, mixing compartment, pedestal, air inlet tube, muffler, etc. For the air inlet tube, the upper side is the air inlet above the water surface and the lower side is connected to the mixing compartment. When the electric power is switched on, the impeller shall rotate and the water shall flow out of the impeller outlet. It shall result in minus pressure in the mixing compartment and air shall enter to mix the liquid. The mixture shall flow out from periphery to fulfill the process to oxygenate the liquid.
Features
High efficiency oxygen dissolving:
It has unique design for gas mixture chamber whose intake air quantity is big. Air can be mixed well with water, and it can produce minute and plenty of air bubble with high air dissolving rate.
Intensive mixing:
The pressure produced by impeller through jet hole produces forceful water flow, which realizes jet after mixed with air to make oxygen move efficiently in water and at the same time achieve good mixing effect, which can maintain the flow rate necessary for activated sludge floating.
Quiet and noise-free:
The machine unit is designed to run in water with low winding number and low noise: overland air-intake duct can be additionally equipped with silencing equipment. Cost can be reduced since no other anechoic room is required.
Easy for installation and maintenance:
There are two types for your selection: equipped with or without automatic attach device. Easy for installation and maintenance, saving operation cost.
Wide range of service:
It is widely used in industrial wastewater treatment, effluent treatment of livestock husbandry and general foul sewer aeration engineering, aeration tank of effluent facilities of factory applied with activated sludge method. It can be used either individually or in a combined way.
Constructive specification:
This submersible jet aerator adopts specially designed aeration pump, which forms the integral unit with air bubble generating section and automatic attach device.
Special aeration pump:
Special aeration pump uses high-performance impeller, which does not block fouls. Therefore, it has long service life.
Air bubble generating section:
This section is composed of air-inlet duct, nozzle holder, gas mixture chamber and divergent pipe. Water is pumped into gas mixture chamber at high speed from nozzle holder connected to pump outlet. Air is inducted into gas mixture chamber through air-inlet duct and is mixed with water flow, then exhausted through divergent pipe.
Automatic attach device:
This equipment is composed of induction duct, directing plate, the attach- unit. During maintenance of equipment, the pump can be directly pulled out from water through induction duct along with the attach device.
