← ScienceWhich outcome results turbulence within desalination reverse osmosis membranes?
A)Increased membrane fouling and reduced flux✓
B)Improved salt rejection at reduced pressures
C)Enhanced membrane cleaning and extended lifespan
D)Decreased energy consumption from lower viscosity
💡 Explanation
Increased local shear stress during turbulence disrupts the boundary layer, causing increased membrane fouling because this disrupts permeate flow. This results in decreased membrane flux rather than improved performance, due to blockage, or lower pump work.
