A common challenge with RO membrane elements is fouling, an issue that can compromise efficiency. While fouling doesn't alter the structure of RO membrane elements, the accumulation of foulants on the membrane surface can greatly diminish its performance.
Proshare Anti-Fouling reverse osmosis (RO) combats fouling by utilizing a unique hydrophilic coating on the membrane surface. This innovation ensures prolonged stable operation. By preventing fouling, the need for frequent cleaning is reduced, leading to lower operational expenses (OPEX) at the water treatment facility.
Proshare Anti- Fouling perfectly meets your requirements for treating urban sewage water in industrial applications.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare The Proshare team has masterfully crafted a groundbreaking new generation of reverse osmosis membranes utilizing cutting-edge polymer interface nano-self-assembly technology. This innovative approach triumphs over the traditional limitations of reverse osmosis membrane development, thanks to two pivotal advancements:
Ultra-Thin Separation Layer: Through the revolutionary application of polymer interface nanotechnology, Proshare has managed to achieve an ultra-thin separation layer, at least three times thinner than conventional polyamide films, which were previously constrained to 100 nm. This monumental advancement dramatically boosts water flux, leading to a remarkable leap in permeability.
Enhanced Performance: The ingenious integration of nanoparticles and specialized hydrophilic polymers has propelled the membrane's capabilities to new heights, significantly improving hydrophilicity, anti-fouling properties, durability, and oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation sets new standards with breakthroughs in four critical areas:
Self-Assembled Nanocomposite Films
By harnessing the power of nano-scale precision control and nano-doping modifications, Proshare creates ultra-thin, highly ordered separation layers via advanced polymer interface nanotechnology. This innovative method surpasses the traditional polyamide membranes' constraints in terms of 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's thickness is precisely managed, achieving an impressive threefold reduction compared to conventional membranes. This achievement translates to >3x greater water flux and 30% reduced energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Surpassing the limitations of polyamide, Proshare employs state-of-the-art hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These innovative materials demonstrate remarkable oxidation resistance (withstanding up to 10 ppm chlorine exposure) and pH stability (stable across a pH range of 1-12).
Anti-Fouling Surface Engineering
The pioneering superhydrophilic surface (boasting a contact angle of <10°) coupled with nanoparticle reinforcement results in a 50% reduction in organic fouling propensity, extending chemical cleaning intervals from 3 to 6 months and slashing maintenance costs by 40%.
