Fouling Resistance RO Membranes

FR, XFR and FR-LD elements for high-COD industrial effluent

Product description

FR membranes integrate advanced anti-fouling technologies to resist organic and microbial contamination. Engineered for high-challenge water sources including paper mill wastewater, dyeing wastewater and thermal power plant effluent, these elements use proprietary surface modification to optimize electrostatic charge and surface smoothness while enhancing hydrophilicity, substantially reducing pollutant and microorganism adhesion.

XFR membranes are the pinnacle of anti-fouling technology, combining optimized formulations, precise reaction conditions and advanced post-treatment. The result is a denser, more hydrophilic selective layer with an ultra-smooth surface, delivering industry-leading resistance to organic fouling with outstanding cleanability.

FR-LD is our flagship fouling-resistant technology, incorporating HDG — Hydrodynamic Spacer Geometrics to optimize feed-channel hydrodynamics, improve flow distribution, minimize localized stagnation and resist feed-channel blockage. FR-LD delivers stable permeate productivity, improved CIP efficiency and controlled differential-pressure development for textile effluent, high-COD wastewater, landfill leachate and industrial water recycling.
