Proshare Pioneering Team Achieves Breakthrough in Revolutionary Reverse Osmosis Membrane Technology
Proshare has led the charge in innovation by developing a cutting-edge generation of reverse osmosis membranes, utilizing advanced polymer interface nano-self-assembly technology. This innovation triumphantly surpasses the constraints of traditional reverse osmosis membrane development through two pivotal advancements:
Ultra-Thin Separation Layer: Through the expert application of polymer interface nanotechnology, our team has successfully minimized the separation layer thickness to an astounding one-third of the conventional polyamide thin film standard (formerly limited to 100 nm). This remarkable achievement significantly amplifies water flux and marks a substantial leap in membrane permeability.
Enhanced Performance Capabilities: The strategic incorporation of nanoparticles alongside specialized hydrophilic polymers has catalyzed extraordinary enhancements in the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance, redefining performance benchmarks.
In contrast to conventional polyamide reverse osmosis membranes, Proshare's pioneering work showcases groundbreaking advancements in four critical dimensions:
Self-Assembled Nanocomposite Films
With the integration of nano-scale precision control and innovative nano-doping modification, ultra-thin and highly ordered separation layers are crafted through polymer interface nanotechnology. This breakthrough surpasses conventional polyamide membranes' limitations in achieving unparalleled thickness uniformity and material diversity.
Enhanced Water Flux and Unprecedented Energy Efficiency
Thanks to the meticulous optimization of the layer-by-layer self-assembly process, the thickness of the functional layer is precisely managed, yielding a 3x reduction when compared to traditional membranes. This transformative approach results in >3x water flux enhancement and 30% reduction in energy consumption.
Innovative Polymer Materials Offering Superior Chemical Stability
Venturing beyond the limits of polyamide, our team employs cutting-edge hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These materials boast unparalleled oxidation resistance (capable of enduring 10 ppm chlorine exposure) and broad pH tolerance (maintaining stability across a wide 1-12 pH range).
