Proshare Team's Pioneering Breakthrough in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our innovative team has masterfully developed a revolutionary next-generation reverse osmosis membrane using advanced polymer interface nano-self-assembly technology. This innovation triumphs over the constraints of traditional reverse osmosis membrane development through two pivotal advancements:
Creation of an Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, our team has achieved a remarkable reduction in separation layer thickness, achieving a layer three times thinner than conventional polyamide films, which were previously limited to 100 nm. This significant advance vastly enhances water flux, leading to a substantial boost in permeability.
Remarkable Performance Enhancements: By incorporating nanoparticles and unique hydrophilic polymers, we have achieved groundbreaking improvements in membrane hydrophilicity, anti-fouling capability, durability, and resistance to oxidation.
In comparison to traditional polyamide reverse osmosis membranes, Proshare's innovative technology showcases breakthroughs in four crucial aspects:
Development of Self-Assembled Nanocomposite Films
Through the integration of nano-scale precision control and nano-doping modification, we create ultra-thin, meticulously ordered separation layers via polymer interface nanotechnology. This cutting-edge approach addresses the challenges of thickness uniformity and material diversity found in conventional polyamide membranes.
Enhanced Water Flux and Superior Energy Efficiency
By refining the layer-by-layer self-assembly process, we exert precise control over the functional layer thickness, achieving a threefold reduction compared to traditional membranes. This innovation results in >3x higher water flux and a 30% decrease in energy consumption.
Novel Polymer Materials with Unrivaled Chemical Stability
Surpassing the limitations of polyamide, our team employs cutting-edge hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These advanced materials offer remarkable oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and broad pH tolerance (maintaining stability across a 1-12 pH range).
Advanced Anti-Fouling Surface Engineering
Our superhydrophilic surface, featuring a contact angle of less than 10°, combined with nanoparticle reinforcement, dramatically reduces the propensity for organic fouling by 50%. This improvement extends chemical cleaning cycles from three months to six months and slashes maintenance costs by 40%.
