PVDF UF (Ultrafiltration) Filter — Function and Role
A PVDF (Polyvinylidene Fluoride) UF filter is a high-performance ultrafiltration membrane made from polyvinylidene fluoride. It is widely used in water treatment as a highly efficient physical barrier, operating with a typical pore size of 0.01 to 0.1 microns.
Core Separation Function
The PVDF UF membrane uses physical sieving driven by low operating pressure (typically 0.1–0.3 MPa / 15–45 psi). It effectively removes:
• Suspended solids (SS) and turbidity
• Colloids and fine particles
• Bacteria and viruses
• Algae, protozoa (such as Cryptosporidium and Giardia), and parasites
• High-molecular-weight organic compounds
Key Advantages of PVDF Material
PVDF is chosen for its exceptional material properties:
• High Mechanical Strength: Resists breaking or stretching under high pressure or during backwashing.
• Excellent Chemical Resistance: Highly tolerant to oxidizing agents (such as chlorine), strong acids, and bases. This allows for aggressive chemical cleaning (CIP) and extends the membrane's lifespan.
