Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our pioneering team at Proshare has ingeniously crafted a new era of reverse osmosis membranes. Utilizing cutting-edge polymer interface nano-self-assembly technology, we have transcended the traditional confines of reverse osmosis membrane innovation through two groundbreaking advancements:
Ultra-Thin Separation Layer: Employing state-of-the-art polymer interface nanotechnology, our team has achieved an extraordinary reduction in the separation layer's thickness, making it at least three times thinner than the conventional polyamide thin film, previously restricted to 100 nm. This astonishing achievement significantly amplifies water flux, leading to a remarkable enhancement in permeability.
Enhanced Performance: With the infusion of nanoparticles and specialized hydrophilic polymers, we've propelled the membrane's hydrophilicity, anti-fouling proficiency, durability, and oxidation resistance to unprecedented heights, setting new standards in membrane technology.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases breakthroughs in four critical dimensions:
Self-Assembled Nanocomposite Films
Through the integration of nano-scale precision control and nano-doping modification, we craft ultra-thin, meticulously ordered separation layers using polymer interface nanotechnology. This revolutionary approach overcomes the constraints of traditional polyamide membranes in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Our optimized layer-by-layer self-assembly process ensures precise control over functional layer thickness, achieving a 3x reduction compared to conventional membranes. This innovation delivers >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Breaking free from polyamide, we employ advanced hydrophilic polymers like modified polysulfones and ceramic-organic hybrids. These trailblazing materials boast exceptional oxidation resistance (enduring 10 ppm chlorine exposure) and pH tolerance (maintaining stability in a pH range of 1-12).
