Polyvinylidene fluoride (PVDF) has gradually become the main development direction of membrane materials due to its excellent oxidation resistance and mechanical strength. Hollow fiber membranes are increasingly widely used in ultrafiltration processes due to their advantages of high filling density, large specific surface area, no need for supports, and reverse cleaning.
PVDF hollow fiber ultrafiltration membrane has become the trend of ultrafiltration membrane development.
