Thickness-controlled polyamide membranes via centrifugal thin-film deposition for improved fouling and high-recovery performance

AI Insight

Researchers developed a method using centrifugal thin-film deposition to fabricate polyamide membranes with precisely controlled thickness for reverse osmosis and nanofiltration applications. By regulating the thickness of the polyamide active layer, the membranes demonstrated reduced fouling susceptibility and improved water recovery rates compared to conventionally manufactured membranes. The controlled architecture allowed for a more uniform and optimized selective layer, enhancing both permeability and rejection performance.

Why it matters

Improved membrane performance in water treatment systems could significantly reduce energy consumption and operational costs in desalination and water purification processes, addressing growing global freshwater scarcity challenges.
