UF Membrane

UF membrane modules use hollow-fiber configurations with pore sizes of 0.01-0.1 um to achieve high-flux filtration of suspended solids, colloids, bacteria, and viruses. Manufactured from modified hydrophilic PVDF or PVC, these membranes deliver consistent permeate quality with turbidity below 0.2 NTU and SDI under 3, making them ideal as RO pretreatment or for direct drinking water production. The outside-in filtration mode handles high-turbidity feed water with strong anti-fouling performance.

Key advantages:

• Membrane material: PVDF or modified PVC with hydrophilic treatment

• Pore size: 0.03 um nominal; MWCO: 100,000 Daltons

• Membrane area: 30-78 m2 per module depending on size

• Operating pressure: 0.1-0.3 MPa; max feed pressure: 0.4 MPa

• Recovery rate: 90-95% with backwash every 30-60 minutes

Typical applications: Drinking water treatment, surface water purification, RO pretreatment, wastewater reclamation, food & beverage processing

FAQ:

Q: What is the difference between PVDF and PVC UF membranes?

A: PVDF offers superior chemical resistance and longer lifespan; PVC provides cost-effective performance for cleaner feed water sources.

Q: How are UF membranes cleaned?

A: Backwashing every 30-60 minutes plus CEB (chemically enhanced backwash) and periodic CIP with NaClO and citric acid.
