1. Product Overview
DuPont™ IntegraTec™ SFP/SFD-2860 are pressurized PVDF hollow fiber ultrafiltration (UF) modules designed for water treatment applications. With a 0.03 μm nominal pore diameter and an outside-in flow configuration, the modules are designed to remove bacteria, viruses, particulates, and colloids. They can also be used as pretreatment to protect downstream processes such as reverse osmosis (RO).The SFP-2860 is listed for industrial applications, while the SFD-2860 is listed as an NSF/ANSI 61 drinking water module.

3. OPERATING PARAMETERS
The following values are taken from the product data sheet. Filtrate flux and flow range are suggested operating ranges. Values marked “maximum” are operating limits and must be observed under the stated conditions.
Parameter | Value / Range |
Suggested filtrate flux at 25°C | 40–90 L/(m²·h) / 24–53 gfd |
Suggested flow range per module | 2.0–6.9 m³/h / 8.8–30.4 gpm |
Operating temperature | 1–40°C / 34–104°F |
Maximum inlet module pressure at 20°C | 6.25 bar / 90.65 psi |
Maximum inlet module pressure at 40°C | 4.75 bar / 68.89 psi |
Maximum operating TMP | 2.1 bar / 30.5 psi |
Maximum operating air scour flow | 12 m³/h / 7.1 scfm |
Maximum backwash pressure | 2.5 bar / 36 psi |
Operating pH | 2–11 |
Maximum NaOCl concentration | 2,000 mg/L |
Maximum Particle Size | 300 μm |
Flow configuration | Outside-in, dead-end flow |
Expected filtrate turbidity | ≤0.1 NTU |
Expected filtrate SDI | ≤2.5 |
Notes:
The stated filtrate flux is specified at 25°C. Actual performance depends on operating and feedwater conditions.
The maximum inlet module pressure varies with temperature and must not be treated as a single pressure limit across the full temperature range.
Before start-up, flush the system to remove shipping solution and remove residual air. Avoid abrupt pressure variations during start-up, shutdown, cleaning, and other operating sequences.
4. Key Features & Benefits
PVDF hollow fiber membrane: Offers high mechanical strength and chemical resistance for water treatment applications.
0.03 μm nominal pore diameter: Supports the removal of bacteria, viruses, particulates, and colloids.
Outside-in, dead-end flow configuration: Allows a wide range of solids in the feed water and can minimize the need for pretreatment processes compared with inside-out configurations.
Hydrophilic PVDF fibers: Support easy cleaning and wettability, helping maintain long-term performance.
Two 2860 variants: SFP-2860 is listed for industrial applications, while SFD-2860 is listed as an NSF/ANSI 61 drinking water module.
