Proshare Pioneering Breakthroughs in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare proudly presents its revolutionary creation: a new era of reverse osmosis membranes engineered using polymer interface nano-self-assembly technology. This trailblazing development surpasses the limitations of traditional reverse osmosis membranes with two critical breakthroughs:
Featherweight Separation Layer: Utilizing state-of-the-art polymer interface nanotechnology, our team has astoundingly reduced the thickness of the separation layer to a phenomenal level-at least three times thinner than conventional polyamide thin films, which were previously limited to 100 nm. This extraordinary advancement significantly boosts water flux, resulting in a considerable increase in permeability.
Superior Performance and Longevity: The integration of nanoparticles with specialized hydrophilic polymers spurs transformative enhancements in membrane hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Prosharehas made strides in four key areas:
Self-Assembled Nanocomposite Film Technology
Through the perfect blend of nanometer-scale precision control and nano-doping modification, we craft ultra-thin, carefully ordered separation layers using polymer interface nanotechnology. This approach exceeds the conventional polyamide membrane limitations in both thickness consistency and material diversity.
Increased Water Flux and Exceptional Energy Efficiency
By mastering the layer-by-layer self-assembly process, we precisely control the thickness of the functional layer, achieving a remarkable threefold reduction compared to traditional membranes. This innovation leads to over 3 times higher water flux and 30% reduced energy consumption.
Innovative Polymer Materials with Supreme Chemical Stability
Breaking free from polyamide constraints, the team employs advanced hydrophilic polymers (such as modified polysulfones) combined with ceramic-organic hybrids. These materials offer unrivaled oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH stability (maintaining integrity across a pH spectrum of 1 to 12).
Expert Anti-Fouling Surface
With a superhydrophilic surface (contact angle <10°), fortified by nanoparticle enhancement, organic fouling potential is reduced by 50%, extending chemical cleaning intervals from 3 to 6 months and reducing maintenance costs by 40%.
