Attachment of organo-selenium to polyamide composite reverse osmosis membranes to inhibit biofilm formation of S. aureus and E. coli

► Organo-selenium is attached to PA composite RO membranes as an anti-fouling agent. ► Surface-treatment of organo-selenium exposed to worst-case biofouling conditions ► Surface-treatment of organo-selenium proved in synthetic wastewater stream ► Organo-selenium surface treatment expressed high affinity for biofilm inhibition.
