← ScienceWhich risk increases when attempting reverse osmosis with degraded polysulfone membranes?
A)Accelerated biofouling film formation
B)Increased concentration polarization effects
C)Molecular chain scission occurs✓
D)Decline permeate flux performance
💡 Explanation
Molecular chain scission increases with compromised polymer membranes during reverse osmosis, because the mechanical stress surpasses interfacial limit triggering chain breakage; therefore membrane stability degrades, rather than effects concerning flux, fouling, or pore polarization at a surface.
