FR – Fouling Resistant BWRO Membranes

//FR – Fouling Resistant BWRO Membranes

BW Series – Industrial Brackish Water RO Membranes

FR – Fouling Resistant BWRO Membranes

IonClear™ FR series RO membrane elements are highly resistant to organic and microbial contamination, and are used to treat water sources such as paper plants waste water, dyeing waste water and industrial waste water from thermal power plants. The proprietary technology alters the electric-static charges and smoothness of the membrane surface, and enhances the hydrophilicity of the membrane surface. These alternatives greatly reduce the pollutants and microorganisms attached to the surface layer, therefore it reduces the fouling rate and extends service life. It is capable to tackle with poor feed water quality.

  • Excellent anti-pollution properties with the special process treated on the membrane surface

  • Suitable for water treatment systems with poor inlet water quality

  • Effectively reduces the frequency of membrane cleaning, thereby prolonging the service life

Flux and rejection rate is based on the following standard test conditions: 1.55 MPa (225 psi) pressure, 77°F (25°C), 2000 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.
