Proshare Revolutionary Achievements in Advanced Reverse Osmosis Membrane Technology
Proshare Proudly unveils its monumental breakthrough: a next-generation reverse osmosis membrane born from the brilliance of polymer interface nano-self-assembly technology. This pioneering development surmounts the barriers of traditional reverse osmosis membranes with two transformative advancements:
Ultralight Separation Layer: Leveraging the pinnacle of polymer interface nanotechnology, our team has masterfully slimmed down the separation layer to an extraordinary degree-at least three times thinner than conventional polyamide films, previously limited to 100 nm. This groundbreaking improvement significantly boosts water flux, achieving an impressive enhancement in permeability.
Enhanced Performance and Durability: With the strategic integration of nanoparticles and specially designed hydrophilic polymers, we have achieved transformative innovations in membrane hydrophilicity, anti-fouling capabilities, durability, and resilience against oxidation.
Compared to traditional polyamide reverse osmosis membranes, Prosharehas pioneered groundbreaking advancements across four critical dimensions:
Self-Assembled Nanocomposite Film Technology
Through the harmonious integration of nanometer-scale precision control and nano-doping modification, we have developed ultra-thin, meticulously structured separation layers using polymer interface nanotechnology. This approach transcends the limitations of conventional polyamide membranes, enhancing thickness uniformity and diversifying material applications.
Enhanced Water Flux and Superior Energy Efficiency
By mastering the art of layer-by-layer self-assembly, we precisely regulate the functional layer thickness, achieving an astonishing 3x reduction compared to traditional membranes. This innovation results in over 3x higher water flux and 30% lower energy consumption.
Innovative Polymer Materials with Exceptional Chemical Stability
Moving beyond polyamide limitations, our team utilizes cutting-edge hydrophilic polymers (e.g., modified polysulfones) in conjunction with ceramic-organic hybrids. These materials offer unparalleled oxidation resistance (withstanding up to 10 ppm chlorine exposure) and pH resilience (maintaining robust stability across a pH range of 1 to 12).
Anti-Fouling Surface Mastery
The ultra-hydrophilic surface, with a contact angle of less than 10°, fortified by nanoparticle enhancement, cuts organic fouling susceptibility by 50%, extending chemical cleaning intervals from 3 to 6 months and reducing maintenance expenses by 40%.
Our esteemed certifications include the prestigious Health & Safety Management System Certificate, the comprehensive Environmental Management System Certificate, and the renowned ISO9001 Quality System Certificate. Each of these accolades is a testament to our unwavering commitment to excellence, sustainability, and the highest standards of quality assurance.
