Engineering summary from PDF text extraction for Spirapro 3838 SR3-NYV Pharmaceutical. Verify every value with the OEM datasheet.
Summary
Product identification
- Membrane Chemistry: Proprietary TFC® polyamide
- Membrane Type: SR™3 – selective rejection nanofiltration
- Observed molecular weight cut-off: 200 daltons
- Construction: Sanitary spiral wound with net outerwrap
- Regulatory Status:
- Passed USP Class VI testing for element components.
- Conforms to FDA food-contact regulations (CFR Title 21).
- Applications: Desalting and separation of antibiotics and APIs
- Options: Feed Spacer: N (31 mil) or V (46 mil)
- Membrane Characteristics: SR™3 elements are selected when desalting and organic concentration is the objective. Selective rejection membranes provide high retention of divalent salts, proteins, and sugars while preferentially passing monovalent salts such as sodium chloride.
Nominal Performance
Test conditions: 5,000 mg/l MgSO₄ in deionized water at 95 psi (6.5 bar) applied pressure, 10% recovery, 77°F (25°C), pH 7.5
| Part Numbers | Model | Minimum Rejection (%) | Active Membrane Area ft² (m²) | Feed Spacer mil (mm) |
|---|---|---|---|---|
| 8383817 | SPIRAPRO 3838 SR3-NYV | 99.0 | 76 (7.1) | 31 (0.8) |
| 8383819 | SPIRAPRO 3838 SR3-VYV | 99.0 | 61 (5.7) | 46 (1.1) |
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)
- Allowable pH - Continuous Operation: 3.0 - 10.0
- Permeate Pressure: Should not exceed baseline (concentrate) pressure at any time (including online, off-line and during transition). Reverse pressure will damage the element.
- Maximum Differential Pressure Per Element: 12 psi (0.8 bar)
- Maximum Differential Pressure Per Vessel: 60 psi (4.1 bar)
Cleaning limits
- Cleaning Temperature Range: 95 - 122°F (35 - 50°C)
- Allowable pH - Clean-In-Place (CIP): 1.8 - 11.0
Water Quality
- Maximum Feed Turbidity: 1 NTU
- Maximum Feed Silt Density Index (SDI): 5.0 (15-minute test)
- Chlorine and Chemical Exposure:
- Free chlorine tolerance rating of 1,000 ppm-hours at 77°F (25°C), pH 8.
- Maximum continuous chlorine exposure limit is 0.2 ppm.
- Sodium metabisulfite (without catalysts such as cobalt) is the preferred chemical to eliminate free chlorine or similar oxidizers in the feed.
- Chlorine tolerance may be significantly reduced if catalyzing metals (e.g., iron) are present or if feed pH and/or temperature conditions differ from stated.
- Cationic Polymers and Surfactants: SR3 membranes may be irreversibly fouled if exposed to cationic (positively charged) polymers or surfactants. Exposure to these chemicals during operation or cleaning is not recommended and will void the warranty.
Mechanical / hydraulic
- Nominal Dimensions:
| Part Numbers | Model | A inches (mm) | B inches (mm) | C inches (mm) |
|---|---|---|---|---|
| 8383817 | SPIRAPRO 3838 SR3-NYV | 38.0 (965) | 3.8 (96.0) | 0.831 (21.1) |
| 8383819 | SPIRAPRO 3838 SR3-VYV | 38.0 (965) | 3.8 (96.0) | 0.831 (21.1) |
- Lubricants: For element installation, use only water or glycerin to lubricate seals. The use of petroleum or vegetable-based oils or solvents may damage the element and will void the warranty.
Storage
- Storage Solution: The SR3 elements are stored in Sodium metabisulfite. Refer to KMS RO/NF cleaning procedures to rinse the element prior to use.
