Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team has trailblazingly developed a cutting-edge new generation of reverse osmosis membranes, ingeniously based on polymer interface nano-self-assembly technology. This groundbreaking innovation triumphs over the constraints of traditional reverse osmosis membrane development with two pioneering advancements:
Ultra-Thin Separation Layer: Leveraging the revolutionary polymer interface nanotechnology, our team has magnificently reduced the separation layer thickness to an astonishing three times thinner than the conventional polyamide thin film, which was previously restricted to 100 nm. This phenomenal breakthrough dramatically boosts water flux, leading to a substantial rise in permeability.
Enhanced Performance: The strategic introduction of nanoparticles alongside specialized hydrophilic polymers has catalyzed transformative advancements in the membrane's hydrophilicity, anti-fouling capability, durability, and extraordinary oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's groundbreaking innovation marks significant breakthroughs in four pivotal areas:
Self-Assembled Nanocomposite Films
With nano-scale precision control and nano-doping modification marvelously integrated, ultra-thin, highly ordered separation layers are crafted using polymer interface nanotechnology. This state-of-the-art approach spectacularly overcomes the limitations of traditional polyamide membranes concerning thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Refining the layer-by-layer self-assembly process, we achieve precise control over the functional layer thickness, reaching a remarkable 3x reduction compared to traditional membranes. This advancement delivers >3x higher water flux and a 30% reduction in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Surpassing polyamide, our team utilizes avant-garde hydrophilic polymers, such as modified polysulfones, and innovative ceramic-organic hybrids. These advanced materials showcase exceptional oxidation resistance (enduring 10 ppm chlorine exposure) and pH tolerance (remaining stable within a 1-12 pH range).
Anti-Fouling Surface Engineering
With a superhydrophilic surface (contact angle <10°) bolstered by nanoparticle reinforcement, organic fouling propensity is reduced by a remarkable 50%, extending chemical cleaning cycles from 3 months to 6 months, and slashing maintenance costs by a noteworthy 40%
