Our Advantages

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare team has innovatively developed a revolutionary generation of reverse osmosis membranes rooted in the cutting-edge polymer interface nano-self-assembly technology. This innovation triumphantly overcomes the confines of traditional methods through two pivotal advancements:
Ultra-Thin Separation Layer: Harnessing polymer interface nanotechnology, the team achieved an extraordinary reduction in the separation layer's thickness, now at least three times more slender than the conventional polyamide thin film, previously constrained to 100 nm. This remarkable breakthrough dramatically elevates water flux, marking a substantial leap in permeability.
Enhanced Performance: The pioneering introduction of nanoparticles and specialized hydrophilic polymers has resulted in awe-inspiring advancements in the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases extraordinary breakthroughs in four key areas:
Self-Assembled Nanocomposite Films
Through the mastery of nano-scale precision control and nano-doping modification, ultra-thin, highly ordered separation layers spring forth, thanks to polymer interface nanotechnology. This ingenious approach overcomes the conventional polyamide membranes' limitations in thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By perfecting the layer-by-layer self-assembly process, the functional layer thickness is expertly controlled, leading to a remarkable 3x reduction compared to traditional membranes. The result is a transformative >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Venturing beyond polyamide, the team employs advanced hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These materials proudly boast exceptional oxidation resistance (withstanding up to 10 ppm chlorine exposure) and pH tolerance (remaining stable across a pH range of 1-12).
Anti-Fouling Surface Engineering
The integration of a superhydrophilic surface with a contact angle of less than 10°, reinforced by nanoparticles, slashes organic fouling propensity by 50%, extending chemical cleaning cycles from three to six months and slashing maintenance costs by 40%.
