Protein-Decorated Reverse Osmosis Membranes with High Gypsum Scaling Resistance.

ABSTRACT: The global challenge of water scarcity has fueled significant interest in membrane desalination, particularly reverse osmosis (RO), for producing fresh water from various unconventional sources. However, mineral scaling remains a critical issue that compromises the membrane efficiency and lifespan. This study explores the use of naturally occurring proteins to develop scaling-resistant RO membranes through an eco-friendly modification method. We systematically evaluate three protein modification techniques, namely, polydopamine (PDA)-assisted coating, protein conditioning, and protein drying, for fabricating membranes resistant to gypsum scaling. Protein conditioning is found to be the most effective approach, resulting in protein-decorated membranes with an exceptional resistance to gypsu
