FR RO membrane is our best-selling upgraded reverse osmosis product for poor raw water quality scenarios, developed based on conventional brackish water RO, belongs to core Water Filter Element (RO & UF Membrane). Ordinary anti-fouling RO element is easy to form organic and biological dirt layer when processing wastewater with high organic content; the special hydrophilic modified coating of FR fouling resistant reverse osmosis greatly weakens pollutant adhesion, extends chemical cleaning cycle, lowers overall operation cost. Widely used for wastewater recycling, food production water treatment, matched with UF membrane and High Flow Filter to construct complete pretreatment system.
Working Principle of FR Anti-fouling RO Membrane
Under standard operating pressure, feed water flows tangentially across surface of FR RO membrane. Pure water molecules penetrate polyamide layer to produce permeate water; salt, organic pollutants, microorganisms are intercepted and discharged with concentrated water. The upgraded smooth hydrophilic coating of fouling resistant reverse osmosis makes pollutants hard to attach to membrane surface, most dirt will be taken away by concentrated water flow continuously, effectively slow down membrane fouling speed compared with ordinary RO elements.

FAQ
Q1 Where should we choose FR RO instead of standard BW RO?
A1 Choose FR when raw water contains abundant organic matter, such as industrial wastewater, food processing water.
Q2 Will anti-fouling coating reduce salt rejection?
A2 The optimized coating maintains same high salt rejection while improving anti-fouling property.
Q3 What pretreatment is required for FR membrane?
A3 UF membrane + high flow security filter are still needed to remove suspended solids.
Q4 What chemical can be used to clean FR RO?
A4 Standard weak acid and weak alkali cleaning agents are applicable for routine cleaning.
