In microfiltration operation, stable flux is maintained while recovery is kept at or above what percentage?

Explanation:
In microfiltration, keeping the permeate flux stable hinges on how much of the feed you recover as permeate. Operators aim for a very high recovery, typically at least 95%, because this level helps control fouling and concentration effects at the membrane surface, allowing the permeate flow to stay steady over time. If recovery is lower, more feed remains as retentate, which can lead to greater buildup near the membrane, faster flux decline, and less predictable performance. By operating at or above 95%, the system maintains a predictable, stable flux while meeting the process’s separation goals.
