Proshare Pioneering Breakthroughs in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare proudly unveils its revolutionary innovation: an extraordinary new generation of reverse osmosis membranes developed through the groundbreaking use of polymer interface nano-self-assembly technology. This advancement shatters conventional reverse osmosis membrane barriers with two game-changing breakthroughs:
Ultralight Separation Layer: By leveraging state-of-the-art polymer interface nanotechnology, our expert team has ingeniously refined the separation layer, achieving a thickness at least three times slimmer than traditional polyamide thin films (which were previously limited to 100 nm). This significant achievement dramatically boosts water flux, resulting in a substantial rise in permeability.
Enhanced Performance and Durability: The integration of nanoparticles combined with specialized hydrophilic polymers drives transformative improvements in membrane hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance.
Compared to conventional polyamide reverse osmosis membranes, Prosharehas realized breakthroughs in four crucial areas:
Self-Assembled Nanocomposite Film Technology
By seamlessly blending nanometer-scale precision control with nano-doping modification, we have crafted ultra-thin, meticulously structured separation layers through polymer interface nanotechnology. This approach surpasses the limitations of traditional polyamide membranes in both uniform thickness and material diversity.
Enhanced Water Flux and Unmatched Energy Efficiency
Through mastering the layer-by-layer self-assembly process, we precisely regulate the thickness of the functional layer, achieving a remarkable 3x reduction compared to traditional membranes. This breakthrough delivers over 3x enhanced water flux and 30% lower energy consumption.
Novel Polymer Materials with Outstanding Chemical Stability
Venturing beyond the confines of polyamide, our team uses cutting-edge hydrophilic polymers (such as modified polysulfones) paired with ceramic-organic hybrids. These advanced materials offer unparalleled oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH resilience (maintaining stability across a pH range of 1 to 12).
Mastery of Anti-Fouling Surface Engineering
The exceptionally hydrophilic surface (contact angle <10°), bolstered by nanoparticle reinforcement, reduces organic fouling potential by 50%, extending chemical cleaning intervals from 3 to 6 months and cutting maintenance expenses by 40%.
