Proshare The Team's Breakthrough in Revolutionary Next-Generation Reverse Osmosis Membrane Technology
Proshare The team has innovatively crafted a groundbreaking new generation of reverse osmosis membranes utilizing cutting-edge polymer interface nano-self-assembly technology, successfully transcending the boundaries faced by traditional reverse osmosis membrane development. This is achieved through two pivotal advancements:
Ultra-Thin Separation Layer: Through the advanced application of polymer interface nanotechnology, the team has triumphantly minimized the thickness of the separation layer to a remarkable degree-at least three times thinner than the conventional polyamide thin film (previously constrained to 100 nm). This exceptional breakthrough significantly amplifies water flux, marking a dramatic enhancement in permeability.
Enhanced Performance: The strategic incorporation of nanoparticles and specialized hydrophilic polymers has propelled pioneering advancements in the membrane's overall hydrophilicity, robust anti-fouling capability, durability, and formidable oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases remarkable breakthroughs in four crucial aspects:
Self-Assembled Nanocomposite Films
Harnessing the meticulous integration of nano-scale precision control and nano-doping modification empowers the fabrication of ultra-thin, highly ordered separation layers through polymer interface nanotechnology. This innovative approach effectively counters the limitations of traditional polyamide membranes, ensuring uniform thickness and material diversity.
Enhanced Water Flux and Energy Efficiency
By masterfully optimizing the state-of-the-art layer-by-layer self-assembly process, the functional layer thickness is meticulously controlled, achieving an impressive 3x reduction compared to conventional membranes. This results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Advancing beyond traditional polyamide, the team employs state-of-the-art hydrophilic polymers, such as modified polysulfones, alongside ceramic-organic hybrids. These cutting-edge materials demonstrate exceptional oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH tolerance (maintaining stability within a pH range of 1-12).
