Test Conditions
| Parameter | Condition A | Condition B |
|---|---|---|
| Temperature | 25 °C | 25 °C |
| Feed Solution, Concentration | 1500 ppm NaCl | 500 ppm NaCl |
| Feed Pressure | 15 bar | 7.5 bar |
| Brine : Permeate ratio | 5 : 1 | 5 : 1 |
| Feed pH | 6.5 - 7.5 | 6.5 - 7.5 |
Operating limits
- Recommended Operating Pressure: < 15.0 kg/cm² (216 psi)
- Maximum: 20 kg/cm² (288 psi)
- Operating Temperature: < 35 °C (95 °F)
- Maximum: 35 °C (95 °F)
- Feedwater Turbidity (SDI₁₅): < 5
- High flux operation on feedwater turbidity greater than 3 or 4 SDI₁₅ generally results in frequent cleaning requirements. SDI₁₅ is measured according to ASTM D4189.
- Feedwater Chlorine Concentration: 0 ppm
- pH Range, Continuous Operation: 3 - 11 (both feed and brine water must meet this range)
- pH Range, Chemical Cleaning: 3 - 11
- Feed Flow Rate per Vessel: < 2’200 l/h (10 gpm)
- Brine Flow Rate per Vessel: > 600 l/h (2.6 gpm)
- Brine/Permeate Flow Ratio (per element): 5 : 1
- Pressure Drop (per Element): 0.5 kg/cm² (7 psi)
- Pressure Drop (per Vessel): 1.0 kg/cm² (14 psi)
- Element(s) must be cleaned when pressure drop increases to 1.5 times of the initial value.
