Why Choose the UF2860
Our PVDF hollow fiber membrane is the perfect balance of performance and value. Its robust PVDF chemistry ensures it can handle demanding feed waters, while its high-strength fibers resist breakage from backwash and air scouring. The membrane reliably produces low-SDI permeate (≤2.5) and exceptionally clear water (turbidity ≤0.1 NTU), which translates directly into reduced cleaning frequency and extended life for downstream RO systems. Its compact footprint and easy-maintenance design make it a cost-effective and reliable workhorse for a wide range of treatment needs.
Frequently Asked Questions
Q1: What is the maximum chlorine concentration the PVDF hollow fiber membrane UF2860 can tolerate?
A: The membrane withstands up to 2000 ppm free chlorine for short‑term cleaning. For continuous operation, keep residual chlorine below 200 ppm to maximize service life.
Q2: How often should chemical cleaning be performed?
A: Frequency depends on feed quality. Typically, online chemically enhanced backwash every 1–4 weeks; intensive CIP every 3–6 months. Monitor TMP rise – clean when TMP increases by 0.05–0.1 MPa from baseline.
Q3: Can the UF2860 be operated in dead‑end mode?
A: Yes. Both dead‑end and cross‑flow modes are supported. Dead‑end gives higher recovery (up to 95%); cross‑flow reduces fouling for high‑turbidity feeds.
Q4: What is the recommended backwash procedure?
A: Backwash every 20–60 minutes with permeate at 0.07–0.15 MPa (0.7–1.5 bar). Include air scour (12–15 m³/h) for 30–60 seconds before backwash. Backwash duration: 30–120 seconds.
