Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare team has innovatively developed a new generation of reverse osmosis membranes based on cutting-edge polymer interface nano-self-assembly technology, shattering the constraints of traditional reverse osmosis membrane development through two pivotal advancements:
Ultra-Thin Separation Layer: By leveraging advanced polymer interface nanotechnology, the team has triumphantly reduced the separation layer thickness to at least three times thinner than the conventional polyamide thin film (traditionally capped at 100 nm). This revolutionary development dramatically enhances water flux, offering a notable leap in permeability.
Enhanced Performance: Incorporating nanoparticles alongside specialized hydrophilic polymers, this innovation has catalyzed astounding advancements in the membrane's hydrophilicity, anti-fouling capability, durability, and resistance to oxidation.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation manifests breakthroughs in four critical areas:
Self-Assembled Nanocomposite Films
Through the integration of nano-scale precision control and nano-doping modification, ultra-thin, highly ordered separation layers are crafted using polymer interface nanotechnology. This groundbreaking approach transcends the limitations of traditional polyamide membranes in achieving consistent thickness and material diversity.
Enhanced Water Flux and Energy Efficiency
By optimizing the layer-by-layer self-assembly process, the functional layer thickness is meticulously controlled, yielding a remarkable 3x reduction compared to traditional membranes. This leads to >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Breaking away from polyamide, the team employs cutting-edge hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These materials exhibit unparalleled oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH tolerance (maintaining stability in a pH range of 1-12).
Anti-Fouling Surface Engineering
The ultra-superhydrophilic surface (boasting a contact angle <10°) coupled with nanoparticle reinforcement slashes organic fouling propensity by 50%, extending chemical cleaning cycles from 3 months to 6 months and reducing maintenance costs by an impressive 40%.
