Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare The Proshare team has ingeniously pioneered a cutting-edge generation of reverse osmosis membranes, leveraging the brilliance of polymer interface nano-self-assembly technology. Through two pivotal advancements, they have transcended the traditional confines of reverse osmosis membrane development:
Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, the team has remarkably achieved a separation layer at least three times thinner than conventional polyamide thin films (which were previously constrained to 100 nm). This revolutionary feat not only amplifies water flux but also drastically enhances permeability.
Enhanced Performance: The infusion of nanoparticles and unique hydrophilic polymers has catalyzed unprecedented advancements in the membrane's hydrophilicity, anti-fouling capabilities, durability, and resistance to oxidation.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation shines with breakthroughs across four vital dimensions:
Self-Assembled Nanocomposite Films
Mastering nano-scale precision control and nano-doping modification, the creation of ultra-thin, exceptionally ordered separation layers is realized through polymer interface nanotechnology. This method triumphs over the usual limitations of thickness uniformity and material diversity found in conventional polyamide membranes.
Enhanced Water Flux and Energy Efficiency
By finely tuning the layer-by-layer self-assembly process, the functional layer thickness is meticulously controlled, yielding a 3x reduction compared to traditional membranes. The result is >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Surpassing polyamide, the team employs sophisticated hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These materials possess remarkable oxidation resistance (withstanding 10 ppm chlorine exposure) and pH tolerance (maintaining stability in a pH range of 1-12).
Anti-Fouling Surface Engineering
The ultra-hydrophilic surface (contact angle <10°) fortified with nanoparticle reinforcement diminishes organic fouling propensity by 50%, doubling chemical cleaning cycles from 3 to 6 months, and reducing maintenance expenses by 40%.
