Fouling
Main cause
- algae, microorganism, cationic foulants.
- We should replace the reverse osmosis membrane periodically.
Decrease the water flux
Increase the energy consumption, and desalination costs
Permeability & Energy consumption
If permeability is a high value, membrane area is decreasing.
It can decrease the costs of the desalination.
