Proshare Revolutionary Achievements in Advanced Reverse Osmosis Membrane Technology
Proshare proudly unveils a revolutionary breakthrough: the latest generation of reverse osmosis membranes, expertly crafted using cutting-edge polymer interface nano-self-assembly technology. This transformative innovation shatters the limitations of traditional reverse osmosis membranes through two game-changing advancements:
Ultralight Separation Layer: By leveraging state-of-the-art polymer interface nanotechnology, our team has achieved an unprecedented reduction in the thickness of the separation layer, making it at least three times thinner than traditional polyamide thin films (formerly confined to 100 nm). This groundbreaking advancement significantly boosts water flux, resulting in an impressive surge in permeability.
Enhanced Performance and Durability: The integration of nanoparticles with specially designed hydrophilic polymers sparks transformative enhancements in membrane hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance.
In comparison to traditional polyamide reverse osmosis membranes, Prosharehas pioneered breakthroughs in four critical areas:
Self-Assembled Nanocomposite Film Technology
By seamlessly merging nanometer-scale precision control with advanced nano-doping modification, we engineer ultra-thin, impeccably ordered separation layers through polymer interface nanotechnology. This approach transcends conventional polyamide membrane limitations in both thickness uniformity and material diversity.
Enhanced Water Flux and Superior Energy Efficiency
Through the mastery of layer-by-layer self-assembly processes, the functional layer's thickness is meticulously controlled, achieving a remarkable 3x reduction compared to traditional membranes. This innovation translates into over 3x increased water flux and 30% reduction in energy consumption.
Innovative Polymer Materials with Exceptional Chemical Stability
Breaking beyond the confines of polyamide, the team utilizes cutting-edge hydrophilic polymers (such as modified polysulfones) paired with ceramic-organic hybrids. These materials deliver unmatched oxidation resistance (withstanding exposure to 10 ppm chlorine) and resilience to pH (retaining stability over a pH range from 1 to 12).
Anti-Fouling Surface Mastery
The superhydrophilic surface (contact angle <10°), enhanced by nanoparticle reinforcement, reduces the likelihood of organic fouling by 50%, extending chemical cleaning intervals from 3 to 6 months and reducing maintenance costs by 40%.
