Our Advantages

Proshare Revolutionizing Reverse Osmosis: The Team's Pioneering Breakthroughs in Next-Generation Membrane Technology
Proshare Our innovative team has masterfully crafted a new generation of reverse osmosis membranes, leveraging the cutting-edge polymer interface nano-self-assembly technology. This advancement marks a revolutionary leap beyond the constraints of traditional membrane development through two pivotal breakthroughs:
Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, our team has dramatically minimized the separation layer thickness, achieving a layer at least three times thinner than the conventional polyamide thin films (traditionally capped at 100 nm). This significant breakthrough translates into a remarkable enhancement of water flux, achieving unprecedented improvements in permeability.
Elevated Performance: Through the strategic incorporation of nanoparticles and specialized hydrophilic polymers, we have unlocked groundbreaking advancements in the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resilience, setting new industry standards.
When compared to the traditional polyamide reverse osmosis membranes, Proshare's groundbreaking innovations exemplify breakthroughs across four critical dimensions:
Self-Assembled Nanocomposite Films
Through the integration of nano-scale precision control and nano-doping modifications, we have pioneered the creation of ultra-thin, highly ordered separation layers via polymer interface nanotechnology. This approach surpasses the limitations of conventional polyamide membranes in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Unmatched Energy Efficiency
By refining the layer-by-layer self-assembly process, we achieve pinpoint control over the functional layer thickness, reducing it by threefold compared to traditional membranes. The result is >3x increased water flux and 30% reduced energy consumption.
Advanced Polymer Materials with Exceptional Chemical Stability
Surpassing polyamide, our team employs cutting-edge hydrophilic polymers, like modified polysulfones, and ceramic-organic hybrids. These materials offer unparalleled oxidation resistance (withstanding up to 10 ppm chlorine exposure) and pH resilience (maintaining stability across a pH range of 1-12).
Pioneering Anti-Fouling Surface Engineering
With a superhydrophilic surface (contact angle <10°) reinforced with nanoparticles, we drastically reduce organic fouling potential by 50%, extending chemical cleaning cycles from 3 to 6 months and slashing maintenance costs by 40%.
