Which measure can help increase oxygen transfer capacity?

Answer and explanation

Correct answer: Increasing aeration rate and agitation speed in a controlled manner

The correct measure is to increase aeration rate and agitation speed in a controlled manner. Higher aeration supplies more oxygen bubbles to the medium, while agitation distributes them uniformly and increases gas–liquid contact. This can increase oxygen transfer capacity. In contrast, reducing aeration or mixing generally lowers oxygen transfer. Exam tip: Remember that both aeration and agitation support oxygen transfer.
