Evaluation of various pretreatment for particle and inorganic fouling control on performance of SWRO Original Research Article

Seawater desalination of interest is rising to overcome water scarcity. Especially, desalination using RO membranes is increasingly being used for production of drinking water for brackish and/or seawater. SWRO has operational problems that can be caused by various membranes fouling including particulate, inorganic, organic and bio-fouling. Membrane-based pretreatment for particle fouling and the integrated membrane systems with MF, NF, and RO were recently introduced to SWRO. However, little information is known for SWRO processes combined with various pretreatments. Eff ects of various pretreatments on performance of SWRO were evaluated in this study.
