Summary
Product Identification
- Product Line: SR3D FOOD & DAIRY NF ELEMENTS, Nanofiltration 4” and 8” Sanitary Element Series
- Membrane Chemistry: Proprietary TFC® polyamide
- Membrane Type: SR3D - selective rejection nanofiltration
- Molecular Weight Cut-off: 200 Daltons
- Construction: Sanitary spiral wound elements with net outerwrap
- Regulatory Status: Compliant with US FDA CFR Title 21, EC Reg. No. 1935/2004, and EU Reg. No. 10/2011. Halal-certified by the Islamic Food and Nutrition Council of America (IFANCA).
- Application: Desalting and separation of proteins, sugars and carbohydrates. SR3D elements provide high retention of divalent salts, proteins, and sugars while preferentially passing monovalent salts such as sodium chloride.

- Diameter: 3.8”, 7.8” or 8.0”
- Length: 38” or 39”
- Feed Spacer: N (31 mil) or V (46 mil)
Nominal Performance
The following performance data is based on test conditions of 5,000 mg/l MgSO₄ in deionized water at 95 psi (6.5 bar) applied pressure, 15% recovery, 77°F (25°C), pH 7.5.

Operating Limits
- Typical Operating Pressure: 200 - 450 psi (13.8 - 31.0 bar)
- Maximum Operating Pressure: 650 psi (44.8 bar)
- Operating Temperature Range: 40 - 122°F (5 - 50°C)
- Maximum Cleaning Temperature: 122°F (50°C)
- Allowable pH - Continuous Operation: 4.0 - 10.0
- Allowable pH - Clean-In-Place (CIP): 1.8 - 11.0
- Design Pressure Drop Per Element: 6 - 10 psi (0.4 - 0.7 bar)
- Design Pressure Drop Per Vessel: 30 - 50 psi (2.1 - 3.4 bar)
- Permeate Pressure: Should not exceed baseline (concentrate) pressure at any time (including online, off-line and during transition). Reverse pressure will damage the element.
- Differential Pressure: Maximum differential pressure limit is 10 psi (0.7 bar) per element. Maximum differential pressure for any length vessel is 50 psi (3.4 bar).
Feed Water
- Maximum Feed Turbidity: 1 NTU
- Maximum Feed Silt Density Index (SDI): 5.0 (15-minute test)
- Chlorine and Chemical Exposure: Residual free chlorine should be removed prior to membrane exposure to prevent premature membrane failure. Sodium metabisulfite (without catalysts such as cobalt) is the preferred chemical to eliminate free chlorine or similar oxidizers.
- Cationic Polymers and Surfactants: Exposure to cationic (positively charged) polymers or surfactants during operation or cleaning is not recommended and will void the warranty, as SR3D membranes may be irreversibly fouled.
