Surface modification of commercial RO membranes. Surface-enriched zwitterionic moieties via post-deposition quaternization reaction. Morphological and compositional characterization of deposited foulant (alginate). Reduced organic foulant-membrane surface molecular interaction. Significant reduction of sodium alginate attachment on modified membrane surface.
