Specialty Membranes SF-R50

SF-R50 is developed on the basis of fouling resistance membrane (FR), suitable for highly polluted water sources with high COD. It is an anti-pollution brackish water reverse osmosis membrane element that has been upgraded in the durability of sheet. Utilizes our fouling-resistant innovations and robust membrane chemistry.

  • Adopt high rejection and fouling resistance sheet, pH cleaning tolerance range (1-13), helps to effectively chemical cleaning against biological and organic pollution and inorganic salt scaling

  • Effectively reduce pollution and improve cleaning efficiency without affecting the water production through 34mil spacer and (400ft²)membrane area Reduce water production resistance and increase flux through the short membrane sheet length design.

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.
