Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our innovative team at Proshare has ingeniously crafted a pioneering generation of reverse osmosis membranes, leveraging cutting-edge polymer interface nano-self-assembly technology. This remarkable advancement demolishes the barriers faced by traditional membranes with two transformative breakthroughs:
Ultra-Thin Separation Layer: Utilizing state-of-the-art polymer interface nanotechnology, our team has achieved an extraordinary feat, reducing the separation layer's thickness to a third of the size of traditional polyamide thin films, which were previously limited to 100 nm. This monumental innovation not only enhances water flux but also significantly boosts overall permeability.
Enhanced Performance: Incorporating nanoparticles and specialized hydrophilic polymers, we've revolutionized the membrane's properties, achieving unprecedented levels of hydrophilicity, formidable anti-fouling capabilities, heightened durability, and exceptional resistance to oxidation.
Compared to conventional polyamide reverse osmosis membranes, Proshare's cutting-edge innovation showcases breakthroughs across four pivotal dimensions:
Self-Assembled Nanocomposite Films
By merging nano-scale precision control with nano-doping modifications, we craft ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This sophisticated approach triumphs over the limitations of traditional polyamide membranes in terms of thickness consistency and material versatility.
Enhanced Water Flux and Energy Efficiency
Through optimization of the layer-by-layer self-assembly process, we achieve precise control over the functional layer thickness, resulting in an astounding 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
Venturing beyond traditional polyamide, we employ advanced hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These cutting-edge materials offer phenomenal oxidation resistance (capable of withstanding up to 10 ppm chlorine exposure) and exhibit pH tolerance (maintaining stability within a pH range of 1-12).
Anti-Fouling Surface Engineering
