Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team has revolutionized reverse osmosis membrane technology with innovative advancements in polymer interface nano-self-assembly, overcoming traditional development barriers through two significant breakthroughs:
Ultra-Thin Separation Layer: Utilizing cutting-edge polymer interface nanotechnology, we have achieved an extraordinary reduction in separation layer thickness, making it at least three times thinner than the 100 nm benchmark of traditional polyamide thin films. This remarkable innovation greatly enhances water flux, enabling us to reach unprecedented levels of permeability.
Enhanced Performance: By integrating nanoparticles with specialized hydrophilic polymers, we've attained remarkable improvements in membrane hydrophilicity, anti-fouling capacity, durability, and oxidation resistance. This leap forward redefines the standards of membrane performance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases transformative advancements across four pivotal aspects:
Self-Assembled Nanocomposite Films
Through nano-scale precision control and nano-doping modification, we create ultra-thin, highly ordered separation layers via polymer interface nanotechnology. This strategy surpasses the limitations in thickness uniformity and material diversity inherent to conventional polyamide membranes.
Enhanced Water Flux and Energy Efficiency
Perfecting the layer-by-layer self-assembly process allows precise control of functional layer thickness, achieving a dramatic 3x reduction compared to traditional membranes. This enhancement provides >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Advancing beyond polyamide, we employ state-of-the-art hydrophilic polymers such as modified polysulfones and ceramic-organic hybrids. These materials deliver outstanding oxidation resistance (withstanding 10 ppm chlorine exposure) and pH tolerance (sustaining stability in 1-12 pH range).
Anti-Fouling Surface Engineering
The creation of a superhydrophilic surface (contact angle <10°) with nanoparticle fortification significantly cuts organic fouling propensity by 50%, extends chemical cleaning intervals from 3 months to 6 months, and slashes maintenance costs by 40%
