DuPont SFP/SFD-2860/2860XP UF Membrane Advanced Pretreatment for RO Systems
The DuPont SFP-2860 UF Membrane is a high-performance ultrafiltration solution designed for industrial water treatment, leveraging advanced hollow fiber technology to excel as a pretreatment for reverse osmosis (RO) systems. CE-certified and made in China, it features hydrophilic PVDF fibers that deliver superior chemical resistance (pH 2–11) and mechanical strength, ensuring reliable operation in harsh conditions. With a 0.03 μm pore size, it removes 99% of bacteria, viruses, colloids, and particulates, protecting downstream RO membranes while maintaining filtrate turbidity ≤0.1 NTU and SDI ≤2.5—critical for consistent high-purity water output.
Key Applications
Ideal for diverse industrial scenarios:
• RO system pretreatment (seawater desalination, municipal water purification)
• Industrial wastewater reuse (manufacturing, chemical plants)
• Cooling tower blowdown recovery
• Compact containerized water treatment plants
• Process water purification for electronics, pharmaceuticals, and food industries

FAQ
Q1: What’s the minimum order quantity?
A1: 1 pc, supporting small-batch trials for system testing.
Q2: How long is delivery?
A2: 5–8 working days with standard export packing to prevent damage.
Q3: Does it need special start-up steps?
A3: Yes—follow pre-install checks (membrane prep, instrument calibration) and refer to the technical manual; NSF/ANSI 61 models need extra conditioning for drinking water.
