Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team has ingeniously engineered a new era of reverse osmosis membranes leveraging the groundbreaking polymer interface nano-self-assembly technology, transcending the boundaries of traditional membrane development with two pivotal innovations:
Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, the team has remarkably minimized the thickness of the separation layer to a mere fraction of traditional polyamide thin films (previously confined to 100 nm). This revolutionary enhancement significantly amplifies water flux, leading to a dramatic surge in permeability.
Enhanced Performance: The strategic incorporation of nanoparticles alongside specialized hydrophilic polymers has spearheaded unprecedented advancements in hydrophilicity, anti-fouling capacity, durability, and oxidative resilience.
In contrast to conventional polyamide reverse osmosis membranes, Proshare's innovation showcases leaps in four fundamental areas:
Self-Assembled Nanocomposite Films
Through the fusion of nano-scale precision engineering and nano-doping enhancements, ultra-thin, highly ordered separation layers are crafted via polymer interface nanotechnology. This methodology obliterates the constraints of traditional polyamide membranes regarding thickness uniformity and material versatility.
Enhanced Water Flux and Energy Efficiency
Perfecting the layer-by-layer self-assembly technology, the functional layer's thickness is meticulously moderated, delivering a 3x reduction compared to standard membranes. This results in >3x amplified water flux and 30% diminished energy usage.
Novel Polymer Materials with Superior Chemical Stability
Stepping beyond the realms of polyamide, the team employs cutting-edge hydrophilic polymers (e.g., modified polysulfones) along with ceramic-organic hybrids. These materials demonstrate outstanding resistance to oxidation (enduring 10 ppm chlorine exposure) and pH adaptability (remaining stable across a pH range of 1-12).
Anti-Fouling Surface Engineering
The ultra-hydrophilic surface (contact angle <10°) coupled with nanoparticle fortification reduces organic fouling potential by 50%, extending chemical cleaning intervals from 3 to 6 months and slashing maintenance expenditures by 40%.
