Proshare Pioneering Breakthroughs in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare proudly unveils its trailblazing innovation: an extraordinary generation of reverse osmosis membranes forged through the state-of-the-art polymer interface nano-self-assembly technology. This advancement triumphs over traditional reverse osmosis membranes with two groundbreaking breakthroughs:
Ultralight Separation Layer Magic: Utilizing advanced polymer interface nanotechnology, our team has ingeniously crafted a separation layer that is astoundingly slim-at least three times thinner than conventional polyamide thin films (once confined to 100 nm). This monumental leap dramatically enhances water flux, providing a substantial boost in permeability.
Heightened Performance and Durability: By integrating nanoparticles with specialized hydrophilic polymers, we have catalyzed transformative advancements in membrane hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Prosharehas achieved remarkable breakthroughs in four critical areas:
Self-Assembled Nanocomposite Film Innovation
Through the perfect fusion of nanometer-scale precision control with nano-doping modification, we pioneer ultra-thin, meticulously ordered separation layers using polymer interface nanotechnology. This method surpasses conventional polyamide membrane limits in both thickness uniformity and material diversity.
Enhanced Water Flow and Superior Energy Efficiency
By perfecting the layer-by-layer self-assembly process, the thickness of the functional layer is precisely controlled, achieving a groundbreaking threefold reduction compared to traditional membranes. This innovation results in a more than threefold increase in water flow and an impressive 30% reduction in energy consumption.
Innovative Polymer Materials with Unmatched Chemical Stability
Surpassing polyamide limitations, the team employs cutting-edge hydrophilic polymers (such as modified polysulfones) along with ceramic-organic hybrids. These materials offer unprecedented oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH resilience (maintaining stability across a wide pH range of 1 to 12).
Mastery of Anti-Fouling Surfaces
The superhydrophilic surface (contact angle <10°), fortified by nanoparticle reinforcement, reduces organic fouling propensity by 50%, extending chemical cleaning intervals from 3 to 6 months and significantly cutting maintenance costs by 40%.
