The SWC 1640 is designed to meet your seawater desalination standards. Hydranautics membrane formulations are designed to accommodate varying levels of seawater salinities worldwide with reliable field-proven performance. SWC seawater desalination membranes are available in high productivity 8-inch and 4-inch elements, all offering the highest levels of salt rejection and a consistently pure end product.
SWC4 1640 Specifications:
- Permeate Flow: 29,000 gpd (109.8 m3/d)
- Salt Rejection: 99.8 % (99.6 % minimum)
- Boron Rejection (Average): 93.0%
- Configuration: Spiral Wound
- Membrane Polymer: Composite Polyamide
- Membrane Active Area: 1700ft2 (158m2)
- Feed Spacer: 28mil (0.71mm)
The stated performance is initial (data taken after 30 minutes of operation), based on the following conditions:
- 32,000 PPM NaCl solution
- 800 psi (5.52 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): 2.0 - 11.0 (1-13)
- Maximum Feedwater Turbidity: 1.0 NTU
- Maximum Feedwater SDI (15 mins): 5.0
- Maximum Feed Flow: 250 GPM (56 m3/h)
- Minimum Ratio of Concentrate to Permeate Flow for any Element: 5:1
- 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 details on operation limits, cleaning pH, and cleaning temperatures.
