Gravity Ultrafiltration Membrane

Gravity Ultrafiltration Membrane

The gravity hollow fiber ultraflltration membrane is produced strictly with State-of-the-art technology for controlling microstructure of polymer separation membrane and membrane microstructure and in­terface functionalization technology, Oxymo have realized the industrialization of high-performance polymer microporous membranes with super hydrophilicity, gradient microporous structure, and ul­tra-high water flux. It is the highest technology product in the ultra-low pressure membrane applica­tion.
