How do you increase do in aeration tank?

To increase dissolved oxygen (DO) levels in an aeration tank, you can enhance aeration efficiency by using fine bubble diffusers or surface aerators, which improve oxygen transfer rates. Increasing the airflow rate and adjusting the tank's hydraulic retention time can also help maintain higher DO levels. Additionally, minimizing organic loading and ensuring proper mixing can prevent oxygen depletion, further supporting optimal DO concentrations. Regular monitoring and adjustments based on operational conditions are essential for maintaining ideal DO levels.
