Microfiltration membranes made from PDVF have excellent chemical resistance to which substance, and what is their typical service life?

• A. Acids and Bases, 12-15 years
• B. Organic Fouling, 15-20 years
• C. Iron Fouling, 8-12 years
• D. Oxidants, 5-10 years

Answer: (D)

PVDF membranes stand out for their resistance to oxidative cleaning agents and disinfectants, such as chlorine and other oxidants. The fluorinated backbone helps resist oxidative attack, so these membranes can handle oxidant-rich cleaning regimes without rapid degradation. Because of this durability under oxidizing conditions, their typical service life is commonly about 5–10 years, though actual life depends on exact cleaning frequency, temperatures, and operating conditions.
