Product Details
PVDF UF membrane HM160 module is constructed with hydrophilic PVDF hollow fibers, potted in a UPVC housing with food-grade epoxy resin. In this configuration, feed water enters the fiber lumens, and permeate flows outward through the membrane wall. This inside-out flow pattern effectively traps suspended solids, colloids, and bacteria on the inner surface of the fibers. One of the main benefits of this design is its exceptional backwash efficiency; foulants are easily dislodged and flushed from the fiber lumen.
The inside‑out configuration allows effective backwash. Routine backwash with permeate or air‑scour removes accumulated foulants. PVDF withstands chlorine up to 2000 ppm (short‑term) and operates continuously at pH 2–12. The membrane runs in dead‑end or cross‑flow mode depending on feed turbidity.
Applications: RO pretreatment, municipal drinking water, industrial wastewater reuse, food and beverage clarification.

FAQ
Q1: HM160 PVDF vs HM160 PAN/PES – what is the key difference?
A: PVDF has better oxidation resistance and tolerates higher chlorine (2000 ppm) during cleaning. PAN and PES are more hydrophilic but less resistant to oxidants. PVDF is preferred for wastewater and high‑fouling applications.
Q2: How does temperature affect the flux of the PVDF UF membrane HM160 membrane?
A: Water viscosity decreases with higher temperature, increasing flux. At 0.1 MPa, design flux is 40–120 L/m²·h at 25 °C. For every 1 °C below 25 °C, flux drops approximately 2–3%. Use the temperature correction curve provided in the technical manual to adjust operating parameters.
Q3: How does the HM160 cope with iron or manganese in the feed?
A: Tolerates Fe ≤0.5 ppm and Mn ≤0.1 ppm. Higher levels require pre‑oxidation and media filtration upstream. If fouling occurs, a 1–2% citric acid CIP effectively removes metal oxide deposits.
Q4: What cleaning solutions are recommended for PVDF?
A: For organic/biofouling: 0.05% NaClO + 0.1% NaOH (pH 10–12). For scale: 1–2% citric acid or 0.1% HCl (pH 2–3). Flush thoroughly after cleaning.
Q5: What typical water recovery can be expected?
A: Dead‑end: 90–95%. Cross‑flow: 80–90%. Recovery depends on feed quality and flux; consult the technical manual for site‑specific corrections.
