Reverse osmosis (RO) desalination technology offers a promising solution for mitigating water scarcity. However, one of the major challenges faced by RO membranes is biofouling, which significantly increases costs. Traditional simulation models often overlook environmental variability and do not incorporate effects membrane-surface modifications.
