Function
Used in aeration basin,aeration grit basin of sewage treatment plants, to fill oxygen and mixing to sewage –sludge mixing liquid, biochemical treatment to sewage or breed aquatics increase oxygen.
Feature
1) compact structure,small occupy area,install convenient
2 ) except air inhale inlet , other parts all diving into water operation,small noise;
3) inhale much air , produce more thin air bubble , with high dissolved air rate;
4) No need supply air source, save air blower, little project investment
5)Adopting Germany ABS submersible sewage pump technique, impeller passage adopt no-jam, safe operation and reliable
Working Principle
QXB submersible centrifugal aeration adopt motor and impeller driven directly, drainage around water forming low pressure area to inhale water flow by using impeller rotary generate centrifugal force , make vacuum in impeller entrance and inhale air, air and water fully mixed to form unique air water mixing liquid in mixing air chamber, and discharge out quickly in the action of centrifugal force.
Due to water flow jet is strong, cause effective water flow circulate, to make the air shear into vast tiny air bubble, greatly increase its surface area, and due to air bubble ascend slowly to make large oxygen dissolved into water, which to make this aerator effective superior than other aerator.
