Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare team has innovatively crafted a pioneering generation of reverse osmosis membranes, leveraging cutting-edge polymer interface nano-self-assembly technology. This advanced approach triumphs over the traditional limitations of reverse osmosis membrane development through two transformative breakthroughs:
Ultra-Thin Separation Layer: Through revolutionary polymer interface nanotechnology, our team has masterfully reduced the separation layer's thickness to a mere fraction-at least three times thinner than the conventional polyamide thin film. This remarkable achievement significantly boosts water flux, ensuring outstanding improvements in permeability.
Enhanced Performance: By infusing nanoparticles and introducing specialized hydrophilic polymers, we have achieved unprecedented enhancements in the membrane's hydrophilicity, anti-fouling capabilities, durability, and resistance to oxidation.
Compared to traditional polyamide reverse osmosis membranes, Proshare's groundbreaking innovation showcases remarkable breakthroughs in four pivotal aspects:
Self-Assembled Nanocomposite Films
Harnessing the power of nano-scale precision control and nano-doping modification, we have created ultra-thin, highly ordered separation layers via polymer interface nanotechnology. This innovative approach surmounts traditional limitations, enhancing thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By meticulously optimizing the layer-by-layer self-assembly process, we precisely control the functional layer's thickness, achieving a significant 3x reduction compared to conventional membranes. This leads to >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Evolving beyond polyamide, we utilize cutting-edge hydrophilic polymers like modified polysulfones and ceramic-organic hybrids. These advanced materials exhibit exceptional oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH tolerance (maintaining stability across a 1-12 pH range).
Anti-Fouling Surface Engineering
With a superhydrophilic surface (contact angle <10°) enhanced by nanoparticle reinforcement, we achieve a 50% reduction in organic fouling propensity, extending chemical cleaning cycles from 3 months to 6 months, and reducing maintenance costs by an impressive 40%.
