Proshare The Team's Groundbreaking Achievements in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our team has ingeniously pioneered a revolutionary generation of reverse osmosis membranes through the advanced polymer interface nano-self-assembly technology. This remarkable development transcends the conventional constraints of traditional membranes by excelling in two transformative advancements:
Remarkably Thin Separation LayerUtilizing state-of-the-art polymer interface nanotechnology, we've achieved a dramatic reduction in the thickness of the separation layer, making it at least three times thinner than the conventional polyamide thin film, previously restricted to 100 nm. This monumental breakthrough significantly boosts water flux, resulting in a profound enhancement in permeability.
Superior Performance EnhancementThe strategic incorporation of nanoparticles along with specialized hydrophilic polymers has catalyzed astonishing advancements in the membrane's hydrophilicity, anti-fouling capability, longevity, and resistance to oxidation.
In comparison to traditional polyamide reverse osmosis membranes, Prosharehas achieved remarkable breakthroughs in four pivotal areas:
Innovative Self-Assembled Nanocomposite Films
Through the integration of nano-scale precision control and nano-doping modifications, we craft ultra-thin, impeccably ordered separation layers using polymer interface nanotechnology. This innovative approach surpasses the traditional polyamide membranes' limitations in uniform thickness and material variability.
Augmented Water Flux and Energy Efficiency
Meticulously optimizing the layer-by-layer self-assembly process allows us to precisely control the functional layer thickness, achieving a reduction of three times compared to traditional membranes. This optimization results in over three times the water flux, along with a substantial 30% reduction in energy consumption.
Pioneering Polymer Materials with Unparalleled Chemical Stability
Venturing beyond polyamide, our team employs innovative hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These cutting-edge materials demonstrate exceptional resistance to oxidation, capable of enduring 10 ppm chlorine exposure, and tolerance to a wide pH range (maintaining stability from pH 1 to 12).
Revolutionary Anti-Fouling Surface Engineering
A superhydrophilic surface, with a contact angle of less than 10°, combined with nanoparticle reinforcement, markedly reduces the tendency for organic fouling by 50%. This advancement extends the intervals for chemical cleaning from 3 to 6 months, effectively decreasing maintenance expenses by 40%.
