Biofouling potential indicators to assess pretreatment and mitigate biofouling in SWRO membranes: A short review

Many desalination plants still struggle to control biological fouling in seawater reverse osmosis (SWRO) systems as there are no standard methods monitor this type of fouling. Strategies biofouling SWRO have been proposed such antifouling coating and lowering potential feedwater through pretreatment processes. Measuring the has gained increased interest due its direct link biofouling. Moreover, approach can be used an early warning system allowing for taking corrective actions processes meet required quality. This article presents methods/tools developed seawater, their applications assess raw feedwater, how these employed membrane systems. The reported removal efficiency during was found low moderate. Threshold values limitation were then based on several lab plant studies. Research provided insight into performance optimisation control. Future research is anticipated determine better identify robust threshold mitigating membranes.
