Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team has pioneeringly crafted a revolutionary new generation of reverse osmosis membranes, propelled by state-of-the-art polymer interface nano-self-assembly technology. This innovation surmounts the conventional constraints of reverse osmosis membrane development through two pivotal advancements:
Ultra-Thin Separation Layer: By leveraging advanced polymer interface nanotechnology, we have triumphantly minimized the separation layer's thickness to just a third of the thickness of traditional polyamide thin films, which were previously restricted to 100 nm. This monumental breakthrough greatly enhances water flux, culminating in a remarkable boost in permeability.
Enhanced Performance: The strategic incorporation of nanoparticles coupled with specialized hydrophilic polymers has culminated in revolutionary advancements in the membrane's hydrophilicity, anti-fouling properties, durability, and oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases groundbreaking advancements across four crucial aspects:
Self-Assembled Nanocomposite Films
Through the seamless integration of nano-scale precision control with nano-doping modification, we have developed ultra-thin, meticulously ordered separation layers via cutting-edge polymer interface nanotechnology. This approach overcomes the inherent limitations of traditional polyamide membranes in achieving uniform thickness and material versatility.
Enhanced Water Flux and Energy Efficiency
By perfecting the layer-by-layer self-assembly process, the functional layer's thickness is meticulously controlled, allowing for a threefold reduction compared to standard membranes. This leads to >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Surpassing the conventional polyamide materials, our team employs cutting-edge hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids, showcasing extraordinary oxidation resistance (withstanding 10 ppm chlorine exposure) and pH tolerance (maintaining stability across a pH range of 1-12).
Anti-Fouling Surface Engineering
The ultra-superhydrophilic surface (contact angle <10°), reinforced with nanoparticles, drastically reduces the propensity for organic fouling by 50%, extending the chemical cleaning cycle from three to six months and slashing maintenance costs by 40%.
