BW Series – Industrial Brackish Water RO Membranes
FRLE – Fouling Resistance & Low Energy BWRO Membranes
IonClear™ FRLE series RO membranes have the characteristic of fouling resistance and low energy. This membrane element is developed for treating water quality with high tendency of biological pollution or organic pollution. Its operating pressure is 30% lower than that of ordinary brackish water reverse osmosis membrane elements, energy consumption is reduced by about 1/3.
-
Reduce the operating energy consumption of system to improve the economic benefits
-
Good anti-pollution performance, suitable for high-pollution inlet water quality

Flux and rejection rate is based on the following standard test conditions: 1.03 MPa (150 psi) pressure, 77°F (25°C), 1500 ppm NaCl solution and pH 8 for feedwater, and 15% recovery.
Operating and Cleaning Limits
- Maximum Operating Pressure 41 bar (600 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.
