A significant challenge faced by RO membrane elements is the issue of fouling, which can impact performance. While fouling doesn't alter the core structure of RO membranes, it does lead to a drastic reduction in performance by accumulating on the membrane surface.
Proshare Anti-Fouling reverse osmosis (RO) effectively combats fouling by utilizing a unique and specialized hydrophilic coating meticulously applied to the membrane surface, ensuring prolonged stable operation. This proactive anti-fouling approach minimizes cleaning intervals, significantly reducing operational expenses (OPEX) in water treatment plants.
Proshare Anti- Fouling is ideally suited for your urban sewage water treatment needs, specifically tailored for industrial applications, ensuring peak efficiency and cost-effectiveness.

Proshare Groundbreaking Advances by Our Team in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team has ingeniously pioneered a revolutionary new generation of reverse osmosis membranes, leveraging cutting-edge polymer interface nano-self-assembly technology. This innovation has shattered the boundaries of traditional reverse osmosis membrane development, achieving two monumental advancements:
Ultra-Thin Separation Layer Mastery: Utilizing state-of-the-art polymer interface nanotechnology, our team has triumphantly minimized the thickness of the separation layer to a remarkable one-third of the conventional polyamide thin film's thickness, which was previously constrained to 100 nm. This exceptional breakthrough exponentially boosts water flux, leading to a dramatic upgrade in permeability.
Unparalleled Enhanced Performance: The infusion of advanced nanoparticles, alongside specialized hydrophilic polymers, has catalyzed extraordinary advancements in the membrane's hydrophilicity. This includes its anti-fouling prowess, robustness, and steadfast oxidation resistance.
In comparison to conventional polyamide reverse osmosis membranes, Proshare's pioneering innovation unveils breakthroughs across four pivotal dimensions:
Self-Assembled Nanocomposite Film Excellence
Through the fusion of nano-scale precision control and nano-doping modification, we craft ultra-thin, meticulously ordered separation layers by harnessing the power of polymer interface nanotechnology. This technique surpasses the conventional polyamide membranes' limitations in terms of thickness uniformity and material versatility.
Exceptional Water Flux and Energy Efficiency
The fine-tuning of the layer-by-layer self-assembly process ensures precise control over functional layer thickness, trimming it down to one-third of traditional membranes. This remarkable precision culminates in >3x greater water flux and a 30% reduction in energy consumption.
Innovative Polymer Materials with Superior Chemical Stability
Venturing beyond conventional polyamide, our team employs state-of-the-art hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These materials stand out for their exceptional oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH resilience (maintaining stability within a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
Our superhydrophilic surface (with a contact angle of less than 10°), paired with robust nanoparticle reinforcement, effectively diminishes organic fouling propensity by up to 50%. This enhancement extends chemical cleaning cycles from 3 months to 6 months, ultimately slashing maintenance costs by 40%.
