Question

Currently the removal of CO2 is too low and it has been proposed to change the deep well aeration with a co-current tower aerator.

1. The following are the advantages of using deep well aeration:
Very high O₂ transfer within an exceptionally small space
Very good removal of gases
Low energy consumption
Not very sensitive to variations in hydraulic load
