← ScienceWhich outcome occurs when reverse osmosis membranes foul due to scaling?
A)Ionic crystal nucleation is accelerated
B)Polymer chain scission increases sharply
C)Membrane hydrolysis rate decreases
D)Flux decline becomes irreversible✓
💡 Explanation
Irreversible flux decline occurs because crystal growth due to exceeding solubility limits causes pore blocking; this is Mineral scaling. These ions bond ionically. Removal is difficult, therefore flux suffers rather than being easily restored during cleaning.
