Why is pure oxygen aeration suitable for jet aerators?
Why is pure oxygen aeration suitable for jet aerators?
Because the jet aerator uses the pressurized water flow to create negative-pressure suction to draw in oxygen, and through shearing and turbulent mixing forms fine, uniformly distributed bubbles; the subsequent multi-stage mixing extends the gas-liquid contact time, and the secondary jet in the tank also strengthens the mixing.
Here are other common questions about pure oxygen jet aeration:
1. How does the jet aerator draw pure oxygen into the water?
The pressurized water flow enters the nozzle from the jet aerator inlet and forms a high-speed jet, creating a vacuum at the throat, which draws the external oxygen into the water flow and mixes it with the liquid phase.
2. What effect does smaller bubbles have on pure oxygen aeration?
The original technical documents point out that smaller bubbles mean a larger specific surface area and a larger gas-liquid contact area, which is therefore more conducive to the mass transfer of oxygen in wastewater.
3. Is the oxygen utilization rate of pure oxygen jet aeration always 90%?
No. 90% is the value recorded in the documents of the ozone tail gas reuse project in the Shanghai Chemical Industry Zone. It only applies to that project and cannot be directly extrapolated as a guaranteed value for other projects.
