Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our dedicated team at Proshare has ingeniously developed a cutting-edge new generation of reverse osmosis membranes, masterfully crafted using polymer interface nano-self-assembly technology. This innovation surmounts the traditional boundaries of reverse osmosis membrane development through two pivotal advancements:
Ultra-Thin Separation Layer: By harnessing the power of polymer interface nanotechnology, our team has achieved an extraordinary reduction in the separation layer's thickness, making it at least three times thinner than conventional polyamide thin films, which were previously limited to 100 nm. This landmark advancement remarkably boosts water flux, resulting in a significant elevation in permeability.
Enhanced Performance: With the strategic integration of nanoparticles and specialized hydrophilic polymers, we've pioneered revolutionary improvements in the membrane's hydrophilicity, anti-fouling capabilities, longevity, and robustness against oxidation.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases transformative breakthroughs in four crucial aspects:
Self-Assembled Nanocomposite Films
Through the incorporation of nano-scale precision control and nano-doping modification, we craft ultra-thin, impeccably ordered separation layers via polymer interface nanotechnology. This ingenious approach triumphs over the conventional limitations in thickness uniformity and material diversity of standard polyamide membranes.
Enhanced Water Flux and Energy Efficiency
By refining the layer-by-layer self-assembly technique, we meticulously control the functional layer's thickness, achieving a remarkable 3x reduction compared to traditional membranes. This leads to >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Beyond the confines of polyamide, our team employs state-of-the-art hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These advanced materials boast unparalleled oxidation resistance withstanding exposures up to 10 ppm chlorine and displaying remarkable pH tolerance maintaining stability across a broad 1-12 pH range.
Anti-Fouling Surface Engineering
The superhydrophilic surface, with a contact angle less than 10°, coupled with nanoparticle reinforcement, reduces the tendency for organic fouling by an impressive 50%. This extends chemical cleaning cycles from 3 months to 6 months, while slashing maintenance costs by 40%.
