  • 32,000 ppm NaCl
  • 600 psi (4.1 MPa) Applied Pressure
  • 77°F (25°C) Operating Temperature
  • 10% Permeate Recovery
  • 6.5 - 7.0 pH Range
Standard Operating Limits:
  • Maximum Applied Pressure: 1000 psig (6.9 MPa)
  • Maximum Chlorine Concentration: < 0.1 PPM
  • Maximum Operating Temperature: 113°F (45°C)
  • pH Range, Continuous (Cleaning): 2-11 (1-13)*
  • Maximum Feedwater Turbidity: 1.0 NTU
  • Maximum Feedwater SDI (15 mins): 5.0
  • Maximum Feed Flow: 16 GPM (3.6 m3/h)
  • Minimum Recovery for any Element: 10 %
  • Maximum Pressure Drop for Each Element: 10 psi

The limitations shown here are for general use. For specific projects, operating at more conservative values may ensure the best performance and longest life of the membrane. See Hydranautics Technical Bulletins for more detail on operation limits, cleaning pH, and cleaning temperatures.
