Too much is not good. Over-aeration wastes energy and can negatively affect process performance. Most wastewater treatment plants operate their aeration zones and aerobic digesters at 1-3 mg/L dissolved oxygen (DO). Anything more may waste DO and energy. Even aerating at 1 or 2 mg/L over the DO setpoint can be extremely wasteful.What are the directions of water movement in the zone of aeration and saturation?
