SW Series – Seawater Desalination RO Membranes
XLE- Extra Low Energy SWRO Membranes
SW-XLE series are low-energy and high-flux membrane elements developed to reduce the energy consumption of the system. It can effectively reduce the energy consumption of the pump, or achieve higher flux than other SWRO models under the same operating pressure, which is suitable for users who pursue higher flux.
-
High rejection rate and high flux
-
Lower energy consumption
-
Improve water production economy

Flux and rejection rate is based on the following standard test conditions: 5.5 MPa (800 psi) pressure, 77°F (25°C), 32000 ppm NaCl solution and pH 8 for feedwater, and 8% recovery.
Operating and Cleaning Limits
- Maximum Operating Pressure 83 bar (1200 psi)
- Maximum Operating Temperature 45°C (113°F )
- Maximum Element Pressure Drop 1.0 bar (15psi)
- pH Range Continuous Operation 2-11
- pH Range Short-Term Cleaning 1-13
- Maximum Feed SDI(SDI ) 5.0
- Free Chlorine Tolerance < 0.1 ppm
Notes
- Permeate flow for individual elements may vary ±15 percent from the value specified.
- Active membrane area guaranteed ±4%.
- Stabilized salt rejection is generally achieved within 24-48 hours of continuous use; depending upon feedwater characteristics and operating conditions.
