A prevalent challenge with RO membrane elements is fouling, which can hamper optimal performance. While fouling does not alter the core structure of RO membrane elements, the accumulation of foulants on the membrane surface can lead to a significant performance decline.
Proshare Anti-Fouling reverse osmosis (RO) proactively combats fouling by employing a proprietary hydrophilic coating on the membrane surface. This innovative approach ensures long-term stable operation. By minimizing fouling, the need for frequent cleaning is reduced, ultimately resulting in lower operational expenditures (OPEX) at the water treatment facility.
Proshare Anti- Fouling is perfectly tailored to meet your urban sewage water treatment needs for industrial applications.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our pioneering team has masterfully crafted a revolutionary new generation of reverse osmosis membranes driven by cutting-edge polymer interface nano-self-assembly technology. By overcoming traditional constraints, our team achieved two significant advancements that redefine membrane development:
Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, the team has impressively minimized the thickness of the separation layer to be at least three times thinner than the conventional polyamide thin film. Previously confined to a thickness limit of 100 nm, this groundbreaking reduction now dramatically boosts water flux and markedly elevates permeability.
Enhanced Performance: Through the strategic incorporation of nanoparticles alongside specialized hydrophilic polymers, we've achieved remarkable strides in advancing the membrane's hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance, setting new standards in membrane performance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases remarkable breakthroughs across four pivotal dimensions:
Self-Assembled Nanocomposite Films
By seamlessly uniting nano-scale precision control with nano-doping modification, we engineer ultra-thin, highly ordered separation layers through polymer interface nanotechnology. This innovative method triumphs over conventional polyamide membrane limitations concerning thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
With meticulous optimization of the layer-by-layer self-assembly process, the functional layer thickness is expertly managed, achieving an impressive 3x reduction compared to traditional membranes. This advancement leads to >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Pushing beyond the confines of polyamide, our team leverages advanced hydrophilic polymers such as modified polysulfones and pioneering ceramic-organic hybrids. These materials exhibit unparalleled oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (maintaining stability in pH ranges from 1 to 12).
Anti-Fouling Surface Engineering
Our ingeniously engineered superhydrophilic surface, with its minimal contact angle of <10°, combined with nanoparticle reinforcement, significantly cuts organic fouling propensity by 50%. This innovation extends chemical cleaning intervals from a demanding 3 months to a more efficient 6 months, reducing maintenance expenses by an impressive 40%.
