Specialty Membranes SF-XR70
SF-XR70 is developed for scenarios such as zero discharge and brine concentration. It is characterized by producing high permeate flux while processing high concentrated brine, thereby reducing operating energy consumption, and has certain anti-pollution properties, suitable for application scenarios such as zero discharge with excellent economic benefits.
-
Able to achieve concentrate greater than 70000PPM
-
Durable, fouling-resistant sheet ensure reliable long-term performance
-
Wide pH tolerance range (pH 1-13) allows for fully effective chemical cleaning under heavy fouling conditions
Product Specifications
Flux and rejection rate is based on the following standard test conditions: 5.5MPa (800 psi) pressure, 77°F (25°C), 32,000 ppm NaCl solution, 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.
