Specifications
| Part Number | Model | Permeate Flow gpd (m³/d) | Chloride Rejection percent | Membrane Area ft² (m²) | Feed Spacer mil (mm) |
|---|---|---|---|---|---|
| 8882300 | 8823 ULP®-400 | 8,500 (32.2) | 98.5 | 400 (37.2) | 28 (0.7) |
| 8883300 | 8833 ULP®-575 Magnum® | 12,200 (46.2) | 98.5 | 575 (53.4) | 31 (0.8) |
Test Conditions: 2,000 mg/l NaCl solution at 125 psi (860 kPa) applied pressure, 15% recovery (20% recovery for Magnum® elements), 77°F (25°C) and pH 7.5.
Performance Notes: Performance specifications are nominal values. Individual element permeate flows may vary +20/-15% from the values shown. Minimum MgSO₄ rejection is 97.5% at 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 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
- Maximum differential pressure per element (40” length): 10 psi (69 kPa)
- Maximum differential pressure per vessel: 60 psi (414 kPa)
- Maximum feed turbidity: 1 NTU (feedwater >0.2 NTU generally results in frequent cleanings).
- Maximum feed SDI (15 minute): 5.0
- Recovery: Single element recovery is approximately 15% for 40” (1,016 mm) long elements and 20% for 60” (1,524 mm) long elements. System recovery is site and application specific.
Chemical Tolerance
- Chlorine and other oxidizing agents (permanganate, ozone, bromine, iodine): Intentional exposure is not recommended.
- Free chlorine tolerance: Approximately 1,000 ppm-hours based on testing at 77°F (25°C), pH 8. This tolerance may be significantly reduced by catalyzing metals (e.g., iron) or different pH/temperature. 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.
- Cationic (Positively Charged) Polymers and Surfactants: Exposure during operation or cleaning is not recommended, as it may cause irreversible fouling.
- Lubricants: For element loading, use only approved silicone lubricant, water, or glycerin for O-rings and brine seals. Petroleum-based lubricants or vegetable-based oils may damage the element and void the warranty.
