The evolution of membrane fouling was investigated in detail to determine its correlation with the cleaning strategy on one hand and the quality of the raw seawater on the other hand. The developed models showed that in terms of cleaning efficiency there are no significant differences between the standard protocol and the optimized operation. This confirms the hypothesis of being able to use the optimized operation in a sustainable manner and still benefit from lower cleaning frequencies. In addition, it has been demonstrated that the use of PCA as monitoring technique to detect abnormal fouling issues is a robust tool. By using PCA, decisions on cleaning sequences or frequencies could be taken dynamically instead of running the system with fixed cycles.
