Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare The Proshare team has ingeniously crafted a revolutionary generation of reverse osmosis membranes, utilizing pioneering polymer interface nano-self-assembly technology. This innovation triumphs over traditional membrane limitations with two notable advancements:
Ultra-Thin Separation Layer: Through the adept application of polymer interface nanotechnology, the team has remarkably diminished the separation layer's thickness to an unprecedented level-at least three times slimmer than the conventional polyamide thin film, which was previously constrained to 100 nm. This extraordinary breakthrough propels water flux to new heights, markedly enhancing permeability.
Enhanced Performance: With the strategic incorporation of nanoparticles and specially designed hydrophilic polymers, the membrane experiences phenomenal advancements in hydrophilicity, anti-fouling properties, durability, and oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases remarkable breakthroughs across four crucial dimensions:
Self-Assembled Nanocomposite Films
By seamlessly integrating nano-scale precision control and nano-doping techniques, the creation of ultra-thin, meticulously ordered separation layers via polymer interface nanotechnology is realized. This innovative approach surpasses the challenges of conventional polyamide membranes in terms of thickness uniformity and material versatility.
Enhanced Water Flux and Energy Efficiency
Through the meticulous refinement of the layer-by-layer self-assembly process, the functional layer's thickness is precisely regulated, resulting in a 3x thickness reduction compared to traditional membranes. This optimization leads to >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Surpassing polyamide, the team employs advanced hydrophilic polymers, such as modified polysulfones, alongside ceramic-organic hybrids. These cutting-edge materials demonstrate remarkable oxidation resistance (enduring 10 ppm chlorine exposure) and pH tolerance (remaining stable within a 1-12 pH range).
Anti-Fouling Surface Engineering
The incorporation of a superhydrophilic surface (contact angle <10°) augmented with nanoparticle reinforcement dramatically reduces the propensity for organic fouling by 50%, thereby extending chemical cleaning cycles from 3 months to 6 months and significantly trimming maintenance costs by 40%.
