Hig aeration basin temperature
WebToo 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. Web20 gen 2024 · Here, at high bubble radius (1.6mm) and low column depth (1m), only 8.3% of the total available O 2 transferred to the bulk. This situation provides a good example where system efficiency could be increased by simply reducing bubble size given a constant aeration basin depth.
