Enhanced Fouling Resistant (FR) Series

 

 

  The surface of FR series membrane elements has the characteristics of lower roughness and higher hydrophilism. Based on all series of RO membrane including brackish water, sea water and running water, Jozzon has developed FR technology with the advantages of reducing the colloid fouling, organics and fouling and advancing the cleaning recovery performance. The inlet conduit with the special inlet angle of 34mil-36mil enhances the fouling resistant performance and effective cleaning to maintain system in the low pressure drop under high-pollution condition.
 
Introduction
Jozzon fouling resistant (FR) series have the advantages of high flux and desalination to be suitable for surface water, underground water, running water and municipal water with salinity of 7000ppm. FR series are mainly applied for industrial water treatment including reuse of reclaimed water and boiler feed water of power station, especially for treatment of industrial effluent with little organic pollutants, municipal sewage and micropollution water.
