| Part Number | Model | Membrane Area ft² (m²) |
|---|---|---|
| 8822210 | ROGA 8040-UF-325 | 325 (30.2) |
Operating limits
- Typical Operating Pressure: 50-75 psi (345 - 515 kPa)
- Maximum Operating Pressure: 150 psi (1,035 kPa)
- Maximum Operating Temperature: 104°F (40°C)
- Maximum Cleaning Temperature: 104°F (40°C)
- Maximum Continuous Free Chlorine: 1 mg/L (or similarly active oxidizing agents such as iodine, bromine, and ozone)
- Allowable pH – Continuous Operation: 3 – 7
- Allowable pH – Short Term Cleaning: 2.5 – 8
- Maximum Differential Pressure Per Element (40" / 1,016 mm long): 10 psi (69 kPa)
- Maximum Differential Pressure Per Vessel: 60 psi (414 kPa)
- Permeate Pressure: Should not exceed feed-concentrate pressure by more than 5 psi (34 kPa) at any time.
- Recovery: Maximum recovery is site and application specific. Single element recovery is approximately 11%.
Feed water
- Maximum Feed Turbidity: 1 NTU
- Maximum Feed SDI (15 minute test): 5.0
- Feedwater pH adjustment: pH should be adjusted to approximately 5.7 to minimize membrane hydrolysis. Effects may become significant above pH 6, potentially reducing membrane life.
