Proshare Pioneering Breakthroughs in State-of-the-Art Reverse Osmosis Membrane Technology
Proshare proudly unveils a revolutionary breakthrough: an extraordinary generation of reverse osmosis membranes designed through advanced polymer interface nano-self-assembly technology. This innovation eclipses the limitations of traditional membranes, boasting two significant advancements:
Ultralight Separation Layer: Utilizing cutting-edge polymer interface nanotechnology, our team has remarkably thinned the separation layer to an unparalleled extent-at least three times sleeker than conventional polyamide thin films, previously limited to 100 nm. This extraordinary enhancement significantly boosts water flux, elevating permeability to new heights.
Enhanced Performance and Durability: The incorporation of nanoparticles, combined with specialized hydrophilic polymers, induces groundbreaking advancements in the membrane's hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Prosharehas accomplished breakthroughs in four critical areas:
Self-Assembled Nanocomposite Film Technology
Through the harmonious integration of nanometer-scale precision control and nano-doping modification, we craft ultra-thin, meticulously ordered separation layers via polymer interface nanotechnology. This method surpasses the conventional constraints of polyamide membranes, achieving superior thickness uniformity and a broader range of materials.
Enhanced Water Flux and Superior Energy Efficiency
By mastering the layer-by-layer self-assembly process, we precisely regulate the thickness of the functional layer, achieving an astounding 3x reduction compared to traditional membranes. This pioneering achievement results in over 3x higher water flux and 30% reduction in energy consumption.
Innovative Polymer Materials with Exceptional Chemical Stability
Surpassing the boundaries of polyamide, our team utilizes cutting-edge hydrophilic polymers (such as modified polysulfones) blended with ceramic-organic hybrids. These materials deliver unmatched oxidation resistance (withstanding exposure to up to 10 ppm chlorine) and pH resilience (sustaining stability across an extensive pH range of 1 to 12).
Anti-Fouling Surface Mastery
The superhydrophilic surface (contact angle <10°), reinforced with nanoparticles, reduces organic fouling susceptibility by 50%, extending chemical cleaning intervals from 3 to 6 months and cutting maintenance costs by 40%.
