HRFR – High Rejection & Fouling Resistance SWRO Membranes

//HRFR – High Rejection & Fouling Resistance SWRO Membranes

SW Series – Seawater Desalination RO Membranes

HRFR – High Rejection & Fouling Resistance SWRO Membranes

SW-HRFR series are developed for seawater with complex water quality or concentrated brine with high hardness and organic matter. The membrane has been specially treated to effectively reduce the adhesion of organic matter and inorganic salts on the membrane surface, and at the same time reduce frequency of chemical cleaning.

  • Adopt the unique anti-pollution rolling design patent and the special treatment process of the sheet to reduce frequency of chemical cleaning

  • Anti-pollution coating is added to the sheet to solve the problem of pollutant adhesion and improve the recovery ability after chemical cleaning

  • Non-oxidation post-treatment process ensure the service life and chemical stability of membranes

  • Adopt short membrane sheet length design to increase the utilization rate of the effective area, make the flux distribution on the membrane surface more uniform, and reduce the fouling rate of membranes

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.
