Proshare Team's Pioneering Leap in Next-Generation Reverse Osmosis Membrane Mastery
Proshare Our team has expertly crafted an avant-garde generation of reverse osmosis membranes, leveraging the cutting-edge polymer interface nano-self-assembly technology. This innovation triumphantly surpasses the confines of conventional development through two revolutionary advancements:
Ultra-Thin Separation Layer: With the strategic application of polymer interface nanotechnology, our team has achieved a remarkable reduction in the separation layer thickness, making it thrice thinner than the conventional polyamide thin film, which was traditionally capped at 100 nm. This innovation considerably amplifies water flux, resulting in a marked enhancement in permeability.
Enhanced Performance: By incorporating cutting-edge nanoparticles and specialized hydrophilic polymers, we have achieved unparalleled advancements in the membrane's hydrophilicity, anti-fouling prowess, rugged durability, and oxidation resilience.
When juxtaposed with traditional polyamide reverse osmosis membranes, Proshare's ingenuity signifies transformative breakthroughs in four pivotal areas:
Self-Assembled Nanocomposite Films
Through the synthesis of nano-scale precision control and nano-doping enhancements, ultra-thin, meticulously ordered separation layers are constructed via polymer interface nanotechnology. This pioneering method transcends the traditional constraints of polyamide membranes in terms of thickness consistency and material versatility.
Supreme Water Flux and Energy Efficiency
By finely tuning the layer-by-layer self-assembly methodology, the functional layer thickness is meticulously controlled, achieving a remarkable 3x reduction compared to conventional membranes. This translates into a phenomenal increase in water flux, over 3x and a significant 30% reduction in energy consumption.
Revolutionary Polymer Materials with Unmatched Chemical Stability
Transcending traditional polyamide, our team employs state-of-the-art hydrophilic polymers, including modified polysulfones, alongside ceramic-organic hybrids. These materials showcase superb resistance to oxidation, withstanding exposure to 10 ppm chlorine, and excel in pH tolerance, retaining stability across a broad pH range of 1 to 12.
