Our Advantages

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare team has innovatively developed a groundbreaking new generation of reverse osmosis membranes. Leveraging cutting-edge polymer interface nano-self-assembly technology, they have skillfully navigated past the limitations of traditional membrane design with two pioneering advancements:
Ultra-Thin Separation Layer: Through the masterful application of polymer interface nanotechnology, the team has achieved an extraordinary reduction in the separation layer's thickness-now at least three times thinner than the conventional polyamide thin film (formerly constrained to 100 nm). This remarkable breakthrough vastly enhances water flux, yielding a significant improvement in permeability.
Enhanced Performance: The strategic incorporation of nanoparticles alongside specialized hydrophilic polymers has spurred revolutionary improvements in the membrane's hydrophilicity, anti-fouling capacity, durability, and oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation boasts breakthroughs in four crucial areas:
Self-Assembled Nanocomposite Films
By harnessing nano-scale precision control and nano-doping modification, this innovation produces ultra-thin, highly ordered separation layers through advanced polymer interface nanotechnology. This revolutionary approach mitigates the constraints of conventional polyamide membranes regarding thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, the functional layer thickness is expertly maintained, achieving a dramatic 3x reduction compared to traditional membranes. This results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Advancing beyond polyamide, the team employs cutting-edge hydrophilic polymers (e.g., modified polysulfones) and innovative ceramic-organic hybrids, showcasing exceptional oxidation resistance (withstanding 10 ppm chlorine exposure) and pH tolerance (remaining stable across a 1-12 pH range).
Anti-Fouling Surface Engineering
The combination of a superhydrophilic surface (contact angle <10°) with nanoparticle reinforcement significantly diminishes organic fouling tendencies by 50%, thereby doubling chemical cleaning cycles from 3 to 6 months and reducing maintenance costs by 40%
