Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our distinguished team at Proshare has ingeniously pioneered a new era of reverse osmosis membranes. Utilizing the cutting-edge polymer interface nano-self-assembly technology, we've transcended traditional development hurdles with two pivotal advancements:
Ultra-Thin Separation Layer: Through the revolutionary application of polymer interface nanotechnology, our team has engineered a separation layer that is at least three times thinner than conventional polyamide thin films, previously constrained to a 100 nm thickness. This monumental breakthrough amplifies water flux, driving a remarkable enhancement in permeability and performance.
Enhanced Performance: The innovative incorporation of nanoparticles alongside specialized hydrophilic polymers has ushered in unprecedented strides in membrane hydrophilicity, anti-fouling prowess, enhanced durability, and robust oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's revolutionary innovation showcases breakthroughs across four distinctive dimensions:
Self-Assembled Nanocomposite Films
By merging nano-scale precision control with nano-doping modifications, we create ultra-thin, impeccably ordered separation layers through state-of-the-art polymer interface nanotechnology. This technique surmounts the challenges faced by conventional polyamide membranes regarding thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, the functional layer thickness is expertly managed, achieving a threefold reduction compared to traditional membranes. The outcome is >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Venturing beyond traditional polyamide, our team employs advanced hydrophilic polymers such as modified polysulfones and ceramic-organic hybrids. These materials boast extraordinary oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (maintaining stability across a pH range of 1-12).
