Proshare Pioneering Advances by Our Team in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our team has ingeniously crafted a revolutionary new generation of reverse osmosis membranes, utilizing polymer interface nano-self-assembly technology. This remarkable innovation triumphs over the traditional barriers of reverse osmosis membrane development with two groundbreaking advancements:
Revolutionary Ultra-Thin Separation Layer: Through the application of polymer interface nanotechnology, our team achieved an exceptional reduction in the thickness of the separation layer, now at least three times thinner than the conventional polyamide thin film (historically constrained to 100 nm). This innovative achievement substantially boosts water flux, marking a momentous leap in permeability.
Elevated Performance: The infusion of nanoparticles, coupled with specialized hydrophilic polymers, has culminated in transformative advancements in the membrane's hydrophilicity, anti-fouling properties, robustness, and resistance to oxidation.
In contrast to traditional polyamide reverse osmosis membranes, Proshare's cutting-edge innovation showcases breakthroughs across four pivotal domains:
Self-Assembled Nanocomposite Films
By incorporating nano-scale precision control with nano-doping modification, we succeed in creating ultra-thin, highly ordered separation layers through polymer interface nanotechnology. This novel approach transcends the limitations of conventional polyamide membranes, offering enhanced thickness uniformity and material diversity.
Superior Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, the functional layer thickness is precisely refined, resulting in a phenomenal 3x reduction compared to traditional membranes. The outcome is >3x increased water flux paired with a 30% reduction in energy consumption.
Innovative Polymer Materials Boasting Exceptional Chemical Stability
Advancing beyond conventional polyamide, our team employs leading-edge hydrophilic polymers, such as modified polysulfones, alongside ceramic-organic hybrids. These cutting-edge materials demonstrate remarkable resistance to oxidation (withstanding exposure to 10 ppm chlorine) and pH resilience (maintaining stability across a pH range from 1 to 12).
Advanced Anti-Fouling Surface Engineering
Our superhydrophilic surface, featuring a contact angle of less than 10°, fortified by nanoparticle reinforcement, effectively diminishes organic fouling propensity by 50%.
