A common challenge encountered with reverse osmosis membrane elements is fouling, a factor that can impact long-term performance. While fouling does not alter the structure of RO membrane elements, it can cause a significant reduction in performance due to the accumulation of foulants on the membrane surface.
Proshare Anti-Fouling reverse osmosis (RO) effectively combats fouling by employing a proprietary hydrophilic coating on the membrane surface. This innovation ensures long-term stable operation, minimizing maintenance and significantly reducing operational costs (OPEX) at water treatment facilities.
Proshare Anti- Fouling is expertly designed to meet your requirements for treating urban sewage water, tailored for industrial application needs.

Proshare: Pioneers in Innovation A Breakthrough in Next-Gen Reverse Osmosis Membrane Technology
Proshare Our team at Proshare has ingeniously crafted a state-of-the-art generation of reverse osmosis membranes, leveraging the cutting-edge polymer interface nano-self-assembly technology. This revolutionary approach transcends the traditional barriers in membrane development, boasting two remarkable advancements:
Ultra-Thin Separation Layer Revolution: Through the dexterous application of polymer interface nanotechnology, our experts have remarkably thinned the separation layer to a mere fraction of the traditional polyamide film thickness (previously constrained to 100 nm). This innovation dramatically boosts water flux, marking a significant leap in permeability.
Performance Elevation: By incorporating nanoparticles and specialized hydrophilic polymers, we have propelled the membrane's hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance to groundbreaking new heights.
In stark contrast to traditional polyamide reverse osmosis membranes, Proshare's innovation heralds breakthroughs in these four pivotal domains:
Self-Assembled Nanocomposite Films Mastery
Through the fusion of nano-scale precision control and nano-doping modification, we achieve ultra-thin, highly ordered separation layers via polymer interface nanotechnology. This avant-garde strategy overcomes the inherent limitations of traditional polyamide membranes in uniformity and material diversity.
Enhanced Water Flux & Energy Efficiency
Optimizing the layer-by-layer self-assembly process allows precise control over functional layer thickness, slashing it by a third compared to conventional membranes. This leads to over 3x superior water flux and a 30% reduction in energy consumption.
Innovative Polymer Materials with Outstanding Chemical Stability
Transcending polyamide, our team employs state-of-the-art hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These materials showcase unparalleled oxidation resistance (withstanding 10 ppm chlorine exposure) and pH resilience (stable across a pH range of 1-12).
Cutting-Edge Anti-Fouling Surface Engineering
Our ultra-hydrophilic surface (contact angle <10°), reinforced by nanoparticles, reduces organic fouling by 50%, doubling the chemical cleaning cycles from 3 months to an impressive 6 months, slashing maintenance costs by 40%.
