ProshareThe Team's Breakthrough in Cutting-Edge Reverse Osmosis Membrane Technology
ProshareOur talented team has exhibited remarkable innovation by developing a trailblazing generation of reverse osmosis membranes, utilizing the revolutionary polymer interface nano-self-assembly technology. This groundbreaking innovation defies traditional reverse osmosis membrane development boundaries with two significant breakthroughs:
Ultra-Thin Separation Layer: By employing state-of-the-art polymer interface nanotechnology, our team has succeeded in reducing the separation layer thickness to at least three times thinner than the conventional polyamide thin film, previously restricted to 100 nm. This astounding achievement elevates water flux to unprecedented levels, representing a significant leap in permeability.
Enhanced Performance: The ground-breaking use of nanoparticles and bespoke hydrophilic polymers has driven remarkable enhancements in hydrophilicity, anti-fouling capabilities, durability, and resistance to oxidation of the membrane.
When compared to traditional polyamide reverse osmosis membranes,Proshare's innovation reveals breakthroughs in four transformative areas:
Self-Assembled Nanocomposite Films
By integrating nano-scale precision control and nano-doping modification, we engineer ultra-thin, meticulously organized separation layers utilizing advanced polymer interface nanotechnology. This innovative method exceeds the limitations of traditional polyamide membranes in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By perfecting the layer-by-layer self-assembly process, the functional layer's thickness is precisely controlled, resulting in a striking 3x reduction compared to conventional membranes. This breakthrough delivers a more than 3x increase in water flux and a remarkable 30% reduction in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Surpassing traditional polyamide, the team employs cutting-edge hydrophilic polymers like modified polysulfones and innovative ceramic-organic hybrids. These materials demonstrate unmatched oxidation resistance (withstanding exposure to 10 ppm chlorine) and comprehensive pH tolerance (maintaining stability across a wide 1-12 pH range).
Anti-Fouling Surface Engineering
Our ultra-superhydrophilic surface (contact angle <10°) paired with nanoparticle reinforcement drastically reduces the potential for organic fouling by 50%, effectively doubling the duration between chemical cleaning cycles from 3 to 6 months and reducing maintenance costs by 40%.
