Specifications
| Part Number | Model | Permeate Flow gpd (m³/d) | Chloride Rejection percent | Active Membrane Area ft² (m²) | Feed Spacer mil (mm) |
|---|---|---|---|---|---|
| 8482002 | 4040-ULP | 1,800 (6.8) | 98.65 | 85 (7.9) | 28 (0.7) |
| 8404008 | 4040-ULP-T | 1,800 (6.8) | 98.65 | 85 (7.9) | 28 (0.7) |
Test Conditions: 2,000 mg/l NaCl solution at 125 psi (860 kPa) applied pressure, 15% recovery, 77°F (25°C), and pH 7.5.
Performance Notes:
- Individual element permeate flows may vary +20% / -15% from the nominal values shown.
- Minimum chloride ion rejection is 97.5% under the specified test conditions.
Operating limits
- Typical Operating Pressure: 100 - 175 psi (690 - 1,208 kPa)
- Maximum Operating Pressure: 350 psi (2,400 kPa)
- Permeate Pressure: Should not exceed feed-concentrate pressure by more than 5 psi (34 kPa) at any time.
- Maximum Differential Pressure per Element: 10 psi (69 kPa)
- Maximum Differential Pressure per Vessel: 60 psi (414 kPa) for FRP overwrap elements; 30 psi (207 kPa) for tapewrap elements.
- Maximum Operating Temperature: 113°F (45°C)
- Maximum Cleaning Temperature: 113°F (45°C)
- Allowable pH – Continuous Operation: 4 - 11
- Allowable pH – Short Term Cleaning: 2.5 - 11 (Limit exposure to extended pH range to 4 hours, once per month)
- Maximum Continuous Free Chlorine: <0.1 mg/l
- Free Chlorine Tolerance: Approximately 1,000 ppm-hours based on testing at 77°F (25°C), pH 8. This tolerance may be significantly reduced if catalyzing metals (e.g., iron) are present or if pH/temperature are different. Sodium metabisulfite is the preferred reducing agent.
- Chloramine Tolerance: Approximately 60,000 ppm-hours in the absence of free chlorine based on testing at 77°F (25°C), pH 8.
- Maximum Feed Turbidity: 1 NTU (Feedwater with turbidity greater than 0.2 NTU generally results in frequent cleanings).
- Maximum Feed SDI (15 minute test): 5
- Maximum Number of Tape Wrap Elements Per Vessel: 3
- Recovery: Maximum recovery is site and application specific. Single element recovery is approximately 15% per element.
- Cationic Polymers and Surfactants: Not recommended due to risk of irreversible fouling.
- Lubricants: Only approved silicone lubricant, water, or glycerin should be used for O-rings and brine seals during element loading. Petroleum-based lubricants or vegetable-based oils may damage the element and void the warranty.
