Liquid Stream Fundamentals Aeration Design

The Standard Oxygen Transfer Rate (SOTR) is the rate at which the SOR is transferred in tap water at 20°C and zero DO. The Actual Oxygen Transfer Rate (AOTR or OTRf) is the rate at which AOR is transferred under field conditions. A variety of factors influence the OTRf and the quantity of oxygen delivered to a process fluid must exceed the AOR
