Equivalent DuPont Holow Fiberf UF Membrane Type SFP 2860
Hollow fiber ultrafiltration membranes are a type of capillary filter membrane that can provide a very large effective membrane area within a unit volume. UF membrane featuring high filtration efficiency. UF membrane widely use in household water purification and industrial water treatment, among other fields.
Membrane filament material: PVDF is currently the mainstream and high-performance choice in the market. It has excellent chemical stability, is resistant to acids, alkalis and oxidation , has high mechanical strength, is not prone to filament breakage, and has strong anti-pollution ability. Other common materials include PES and PAN.
Flow channel structure
External pressure type: The water to be treated flows through the outside of the membrane filament, while clean water seeps out from the inside of the membrane filament. This structure has a larger dirt-holding capacity and is more resistant to clogging. It is suitable for treating water with a high content of suspended solids, such as wastewater and sewage.
>>Internal pressure type: The water to be treated flows inside the membrane filament, while clean water seeps out from the outside of the membrane filament.
