Test Conditions
| Parameter | Condition A | Condition B | Unit |
|---|---|---|---|
| Temperature | 25 | 25 | °C |
| Feed Solution, Concentration | 1500 | 500 | ppm NaCl |
| Feed Pressure | 15 | 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
- Feedwater Chlorine Concentration: 0 ppm
- pH Range, Continuous Operation: 3-11 (Both feed and brine water must meet this range)
- pH Range, Chemical Cleaning: 2-11
- Feed Flow Rate per Vessel: < 650 l/h (3 gpm)
- Brine Flow Rate per Vessel: > 250 l/h (1 gpm)
- Brine/Permeate Flow Ratio: 5 : 1 (for each single element)
- Pressure Drop (per Element): 0.5 kg/cm² (7 psi)
- Pressure Drop (per Vessel): 1.0 kg/cm² (14 psi)
Notes on Operating Limits:
- The recommended design range signifies safe operational and design conditions under low fouling and scaling. Operating outside this range may reduce effective membrane life.
- High flux operation (high permeate flow rate per single element) with feedwater turbidity greater than 3 or 4 SDI₁₅ generally leads to frequent cleaning. Operating pressure should be set to maintain the desired flux rate.
- SDI₁₅ is measured according to ASTM D4189.
- Cleaning and sterilization must follow recommendations in the Technical Bulletin.
- The Brine Flow Rate per Vessel may be reduced when there is a low possibility of fouling and scaling.
- Elements must be cleaned when pressure drop increases to 1.5 times the initial value.
