Abstract

Recently, surface modification of reverse osmosis (RO) membranes has gained increasing attention. For example, some of the commercial thin-film-composite (TFC) polyamide (PA) membranes are coated to introduce hydroxyl groups to the PA surface. Among others hydrophilicity and low surface roughness are the key factors in the development of low-fouling surfaces for TFC-PA membranes. The main focus of the recent study was to develop and evaluate different thin coating technologies, which could have potentiality to introduce low-fouling performance on TFC-PA membrane surface. The selected thin coating technologies included inorganic atomic layer deposition (ALD) and antibacterial polyvinyl alcohol (PVA) based polymer films.
