Features
High efficiency oxygen dissolving
It has unique design for gas mixturechamber whose intake air quantity
is big.It can be mixed well with water,and can produce minute and
plenty ofair bubble with high airdssolving rate.
a Intensive mixing
The pressure produced by impeller through jet hole produces forceful
water flow,which realizes jetafter mixed with air to make oxygen move
efficiently in water and at the same time achieve good mixing effect,
which can maintain the fow rate necessary for activated sludge floating.
Quiet and noise-free
The machine unit is designed to run in water with lowwinding 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 auto-
matic attach device.Easy for installation and maintenance,saving op-
eration cost.
Wide range of service
It is widely used in industrial wastewatertreatment,effluent treatment
oflivestock husbandry and general foul sewer aeration engineering,
aeration tank of effluent facilities of factory applied with activated sludge
method.It can beused either individuallyor in a combined way.
Constructive specification
This submersible jet aerator adopts specially designed aeration pump
which formsthe integral unit with air bubble generating section and auto-
matic attach device.
Special aeration pump
Specialaeration pump uses high-performance impeller,which does not
blockfouls.Therefore,it has longservice 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
intogas mixture chamber through air-inlet duct and is mixed withwater
flow,then exhausted through divergent pipe.
Automatic attach device
This equipmentis composed of induction duct,directing plate,theattach-
unit.During maintenance of equipment,the pump can be directly pulled
