Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare team has innovatively developed a revolutionary new generation of reverse osmosis membranes by harnessing cutting-edge polymer interface nano-self-assembly technology. We've shattered the traditional barriers that have held back reverse osmosis membrane development, thanks to two groundbreaking advancements:
Ultra-Thin Separation Layer: Through the pioneering use of polymer interface nanotechnology, our team has achieved a remarkable feat by reducing the separation layer's thickness to one-third of the conventional polyamide thin film (historically capped at 100 nm). This significant breakthrough dramatically boosts water flux, culminating in a remarkable surge in permeability.
Enhanced Performance: The infusion of nanoparticles alongside specialized hydrophilic polymers has propelled us to the forefront of innovation, markedly elevating the membrane's hydrophilicity, anti-fouling prowess, durability, and resilience to oxidation.
In comparison to conventional polyamide reverse osmosis membranes, Proshare's innovation marks significant progress in four pivotal areas:
Self-Assembled Nanocomposite Films
The fusion of nano-scale precision control with nano-doping modification enables the formation of ultra-thin, impeccably ordered separation layers using polymer interface nanotechnology. This cutting-edge approach surmounts the traditional polyamide membrane hurdles of inconsistent thickness and limited material variety.
Enhanced Water Flux and Energy Efficiency
By perfecting the layer-by-layer self-assembly technique, the functional layer thickness is meticulously managed, achieving an impressive threefold reduction when compared to conventional membranes. This innovation culminates in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Evolving beyond traditional polyamide, our team employs state-of-the-art hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These materials boast outstanding oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and impressive pH tolerance (maintaining stability across a 1-12 pH spectrum).
Anti-Fouling Surface Engineering
The ultra-hydrophilic surface (contact angle <10°), bolstered by nanoparticle reinforcement, diminishes organic fouling potential by 50%, thereby extending chemical cleaning intervals from 3 months to 6 months and slashing maintenance costs by 40%.
