delayed aeration method

What is the difference between the complete mixing method and the delayed aeration method in the activated sludge process for wastewater treatment?
:) Delayed aeration activated sludge process: ① Due to the low load, the volume of the delayed aeration tank is large, resulting in a significant floor area requirement. ② It is sensitive to changes in water quality and quantity. ③ Sludge production is low. ④ It provides good treatment efficiency. The delayed aeration activated sludge process has a higher BOD removal rate than the conventional activated sludge process. In the delayed aeration activated sludge process, the activated sludge remains in the endogenous respiration phase.
