Specialty Membranes SF-R100
SF-R100 is an upgraded product developed on the basis of R50. While ensuring the cleaning resistance ability, it changes the charge characteristics of the membrane surface through the modification process, thus greatly reducing the adhesion of organic matter, and is applied to near-zero emissions and difficult organic wastewater treatment.
-
Effectively reduce the cleaning frequency as high as 30-50% through special modification on membrane surface
-
Wide pH tolerance range (1-13) brings effective chemical cleaning against biological and organic fouling and inorganic salt scaling Low operating pressure help save energy consumption under the condition of same permeate flux
Product Specifications
Flux and rejection rate is based on the following standard test conditions: 1.55 MPa (225 psi) pressure, 77°F (25°C), 2,000 ppm NaCl, solution, 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.
