Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our pioneering team has ingeniously crafted an advanced generation of reverse osmosis membranes utilizing cutting-edge polymer interface nano-self-assembly technology. By harnessing this revolutionary approach, we have shattered the conventional barriers of traditional reverse osmosis membrane development through two groundbreaking advancements:
Ultra-Thin Separation Layer: Leveraging the power of polymer interface nanotechnology, we have remarkably diminished the thickness of the separation layer to a breakthrough level, at least three times thinner than the conventional polyamide thin film, which was previously constrained to 100 nm. This innovative stride significantly boosts water flux, delivering an outstanding enhancement in permeability.
Enhanced Performance: Our innovative introduction of nanoparticles and distinctive hydrophilic polymers has ushered in unprecedented advancements in the membrane's hydrophilicity, anti-fouling capability, durability, and resistance to oxidation
In comparison to traditional polyamide reverse osmosis membranes, Proshare's cutting-edge innovation showcases advancements in four pivotal areas:
Self-Assembled Nanocomposite Films
The fusion of nano-scale precision control with nano-doping modification empowers the formation of ultra-thin, meticulously organized separation layers through polymer interface nanotechnology. This sophisticated approach surpasses the constraints of conventional polyamide membranes concerning 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's thickness is precisely fine-tuned, achieving a remarkable 3x reduction compared to traditional membranes. This meticulous precision results in >3x elevated water flux and an impressive 30% reduction in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Expanding beyond the confines of polyamide, our team adopts state-of-the-art hydrophilic polymers, such as modified polysulfones, and innovative ceramic-organic hybrids. These revolutionary materials exhibit remarkable resistance to oxidation (withstanding exposure to 10 ppm chlorine) and tolerance to pH variations (remaining stable across the 1-12 pH spectrum).
Anti-Fouling Surface Engineering
The ultra-hydrophilic surface, characterized by a contact angle of less than 10°, combined with nanoparticle reinforcement, diminishes the propensity for organic fouling by 50%. This advancement extends chemical cleaning intervals from 3 months to a generous 6 months, thereby slashing maintenance expenditures by 40%.
