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.
Test Conditions
The stated performance is initial (data taken after 30 minutes of operation), based on the following conditions:
- 1500 PPM NaCl solution
- 225 psi (1.55 MPa) Applied Pressure
- 77 F (25 C) Operating Temperature
- 15% Permeate Recovery
- 6.5 - 7.0 pH Range
Mechanical / hydraulic
- A: 40.0 inches (1016 mm)
- B: 7.89 inches (200 mm)
- C: 1.125 inches (28.6 mm)
- Weight: 36 lbs. (16.4 kg)
All membrane elements are supplied with a brine seal, interconnector, and o-rings. Elements are vacuum sealed in a polyethylene bag containing less than 1.0% sodium meta-bisulfite solution, and then packaged in a cardboard box.
Permeate flow for individual elements may vary ±15 percent. Membrane active area may vary ±4%.
