A pervasive issue with RO membrane elements is fouling. While fouling does not alter the fundamental structure of RO membrane elements, it can severely impact performance due to the accumulation of foulants on the membrane surface.
Proshare Anti-Fouling reverse osmosis (RO) effectively combats fouling by utilizing a proprietary hydrophilic coating on the membrane surface, ensuring prolonged stable operation. By minimizing fouling, it decreases cleaning frequency, ultimately reducing operational expenses (OPEX) for water treatment facilities.
Proshare Anti- Fouling perfectly addresses your need for treating urban sewage water for industrial applications, delivering unmatched performance and reliability.

Proshare Our Team's Revolutionary Breakthrough in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our expert team at Proshare has ingeniously crafted a revolutionary new era of reverse osmosis membranes, leveraging state-of-the-art polymer interface nano-self-assembly technology. This groundbreaking innovation transcends the traditional boundaries of reverse osmosis membrane development, marked by two pivotal advancements:
Innovative Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, our team has remarkably minimized the separation layer thickness to an impressive dimension, at least three times thinner than the conventional polyamide thin film, which was previously confined to 100 nm. This significant stride greatly boosts water flux, delivering a remarkable enhancement in permeability.
Optimal Enhanced Performance: With the integration of nanoparticles and cutting-edge hydrophilic polymers, we've achieved transformative progress in advancing the membrane's hydrophilicity, anti-fouling capacity, longevity, and remarkable oxidation resistance.
In comparison with traditional polyamide reverse osmosis membranes, Proshare's pioneering innovation showcases breakthroughs in four critical domains:
Groundbreaking Self-Assembled Nanocomposite Films
Through a seamless blend of nano-scale precision control and nano-doping modification, we craft ultra-thin and highly ordered separation layers via advanced polymer interface nanotechnology.
