PSI MEMBRANE® Pro-XFR Thin Film Nanocomposite (TFN) This cutting-edge, anti-fouling membrane is meticulously engineered for reverse osmosis plants tackling rigorous water and wastewater challenges. Ideal for those seeking a premium membrane solution that delivers superior water purity, enhanced fouling resistance, and magnificent energy efficiency.
Key Feature:
- Achieves 30% lower Pressures :Guarantee exceptional salt-rejection performance with 30% reduction in operating pressures
- Reduced Cleaning Frequency:The TFN membrane showcases remarkably diminished microorganism and inorganic contaminant infiltration, leading to decreased cleaning intervals.
- Wide Cleaning pH Range (1-13):Provides unmatched cleaning efficiency, resilience, and longevity thanks to its extensive cleaning pH range and superb chemical resistance.
Key Applications:
Ideal for softening, generating ultra-pure water, and water reclamation in
pharmaceutical, electronics, power, petrochemical, refinery, and food&beverage industries, as well as municipal applications.etc.
A prevalent issue with RO membrane elements is fouling. Though fouling does not alter the fundamental structure of RO membrane elements, the accumulation of foulants on the membrane surface can severely impair its performance.
Proshare Extreme Anti-Fouling reverse osmosis (RO) innovatively prevents fouling through a specialized hydrophilic coating on the membrane surface, which ensures prolonged stable operation. By mitigating fouling, the reduced need for cleaning ultimately lowers OPEX at water treatment facilities.
Proshare Extreme Anti- Fouling perfectly meets your requirements for treating urban sewage water for industrial application.
