Our Advantages

Proshare Pioneering Advancements in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our dedicated team has ingeniously crafted a next-generation reverse osmosis membrane, leveraging revolutionary polymer interface nano-self-assembly technology. We've shattered the barriers of traditional reverse osmosis methodologies through two pivotal breakthroughs:
Ultra-Thin Separation Layer: Deploying state-of-the-art polymer interface nanotechnology, our team has achieved a phenomenal reduction in the separation layer, rendering it more than three times thinner than the conventional polyamide thin films (historically capped at 100 nm). This extraordinary innovation results in dramatically enhanced water flux and a remarkable leap in permeability.
Elevated Performance Characteristics: With the strategic incorporation of nanoparticles and specially-engineered hydrophilic polymers, we've realized unprecedented advancements in the membrane's hydrophilicity, anti-fouling capabilities, durability, and oxidation resilience.
In stark contrast to conventional polyamide reverse osmosis membranes, Proshare's cutting-edge innovation marks significant advancements in four crucial dimensions:
Self-Assembled Nanocomposite Films
Through the seamless integration of nano-scale precision engineering and nano-doping refinement, we construct ultra-thin, impeccably ordered separation layers via polymer interface nanotechnology. This breakthrough surmounts the challenges of traditional polyamide membranes in terms of thickness consistency and material versatility.
Enhanced Water Flux and Superior Energy Efficiency
By fine-tuning the layer-by-layer self-assembly methodology, we've meticulously controlled the functional layer's thickness, achieving a threefold reduction compared to traditional membranes. This precision engineering results in over thrice the water flux and 30% reduction in energy consumption.
Innovative Polymer Materials with Extraordinary Chemical Stability
Beyond the confines of polyamide, our team harnesses cutting-edge hydrophilic polymers (such as advanced polysulfones) and ceramic-organic hybrids. These state-of-the-art materials offer unparalleled resilience to oxidation (withstanding 10 ppm chlorine exposure) and exceptional pH endurance (maintaining stability across a pH spectrum of 1-12).
Advanced Anti-Fouling Surface Engineering
Boasting a superhydrophilic surface (contact angle <10°) reinforced with nanoparticles, our innovation reduces organic fouling susceptibility by 50%, extends chemical cleaning intervals from 3 months to 6 months, and slashes maintenance costs by 40%
