Aerator-mixer DAWT

The Bottom aerators (DAWT) can be used for oxygenating and mixing in fermentor treatment. It integrates the pump, Air-blower, Gas-liquid mixers as one. It can be operated under the tank, so the oxygen supply is free of blind corner. The aerator is composed of star-type impeller and stator(distributor) and air pipe. The rotation of impeller makes the stator vacuum, and suck the air through the pipe, the water and the air enter into the impeller through the entry between the rotor and stator, they are fully mixed in the impeller, the gas is dispersed into a small bubble of about 100 microns in diameter, that forms a huge area of the gas liquid. It achieves the highly effective of transporting and mixing oxygen. BOAO's aerator is used for oxygen supplying and gas liquid mixing of variety of fermentation tanks but mainly used for high efficience of oxygenatin and mixing mass transfer: Biopharmaceutical: biopharmaceutical fermentation oxygen supplying. Food: vinegar fermentation oxygen supplying. Beveages: vinegar drink fermented oxygen supplying.
