Our Advantages

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our dedicated Proshare team has masterfully crafted an innovative generation of reverse osmosis membranes, leveraging cutting-edge polymer interface nano-self-assembly technology. This revolutionary approach transcends the constraints of conventional reverse osmosis membrane development through two remarkable advancements:
Ultra-Thin Separation Layer: Utilizing state-of-the-art polymer interface nanotechnology, our team has triumphantly minimized the thickness of the separation layer to a mere fraction of traditional polyamide thin films, previously capped at 100 nm. This achievement dramatically boosts water flow rate, setting new standards in permeability.
Enhanced Performance: The strategic infusion of nanoparticles coupled with advanced hydrophilic polymers has resulted in extraordinary enhancements in the membrane's hydrophilicity, anti-fouling prowess, durability, and resistance to oxidation.
Compared to traditional polyamide reverse osmosis membranes, Proshare's cutting-edge innovation showcases transformative breakthroughs in four pivotal areas:
Self-Assembled Nanocomposite Films
Through the seamless integration of nano-scale precision control and nano-doping modification, Proshare pioneers the creation of ultra-thin, highly ordered separation layers via advanced polymer interface nanotechnology, surmounting the limitations of conventional membranes in thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By refining the layer-by-layer self-assembly technique, the functional layer's thickness is meticulously managed, achieving a remarkable 3x reduction compared to traditional membranes. This advancement translates into >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Moving beyond the constraints of polyamide, Proshare's team leverages cutting-edge hydrophilic polymers, like modified polysulfones, and ceramic-organic hybrids. These pioneering materials demonstrate exceptional oxidation resistance (withstanding up to 10 ppm chlorine exposure) and pH tolerance (maintaining stability across a pH range of 1 to 12).
Anti-Fouling Surface Engineering
The ultra-hydrophilic surface, with a contact angle of less than 10 degrees, combined with nanoparticle reinforcement, diminishes organic fouling potential by an impressive 50%. This innovation extends chemical cleaning cycles from 3 to 6 months, effectively reducing maintenance expenses by 40%.
