Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our pioneering team has spearheaded the development of a revolutionary generation of reverse osmosis membranes utilizing cutting-edge polymer interface nano-self-assembly technology. This brilliant innovation triumphs over the constraints of traditional reverse osmosis membrane design by achieving two remarkable advancements:
Ultra-Thin Separation Layer: Leveraging the power of polymer interface nanotechnology, our team has remarkably reduced the separation layer's thickness to at least threefold thinner than the conventional polyamide thin film, which was constrained to 100 nm. This milestone dramatically boosts water flux, ensuring a significant leap in permeability.
Enhanced Performance: Through the infusion of nanoparticles and innovative hydrophilic polymers, we've attained groundbreaking enhancements in the membrane's hydrophilicity, fouling resistance, longevity, and oxidation resilience.
Compared to traditional polyamide reverse osmosis membranes, Proshare's trailblazing technology showcases unprecedented breakthroughs across four pivotal dimensions:
Self-Assembled Nanocomposite Films
Integrating nano-scale precision and nano-doping modifications, this technology fabricates ultra-thin, highly ordered separation layers through polymer interface nanotechnology. This sophisticated method transcends the bounds of conventional polyamide membranes in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By perfecting the layer-by-layer self-assembly process, we've achieved precise control of functional layer thickness, leading to a 3x reduction compared to traditional membranes. This innovation results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Surpassing the limitations of polyamide, our team employs advanced hydrophilic polymers like modified polysulfones and ceramic-organic hybrids. These materials exhibit superior oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (remaining stable across a pH range of 1-12).
Anti-Fouling Surface Engineering
Featuring a superhydrophilic surface (contact angle <10°) complemented by nanoparticle reinforcement, this engineering marvel reduces organic fouling propensity by 50%, thereby extending chemical cleaning cycles from 3 months to 6 months, resulting in a 40% reduction in maintenance costs.
