Operating Limits / Design Conditions
The following are recommended design conditions for safe operation under conditions with not much fouling and scaling. Operating outside these ranges may reduce effective membrane life.
- 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.
- 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)
- This figure may be reduced when there is low possibility of fouling and scaling.
- 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)
- Element(s) must be cleaned when pressure drop increases to 1.5 times of the initial value.
Mechanical / Hydraulic
The elements are approximately 4 inches in diameter and 40 inches long.
- Length: 40'' (1016 mm)
- Diameter: 4'' inch (101 mm)
- Permeate Tube Diameter (A): 0.75'' (19 mm)
- Permeate Tube Diameter (B): 1'' (25.4 mm)
- Element body diameter (excluding brine seal): 3.9'' (99 mm)
