Proshare Pioneering Breakthrough in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our innovative team at Proshare has triumphantly crafted a new generation of reverse osmosis membranes leveraging the revolutionary polymer interface nano-self-assembly technology. This cutting-edge development shatters the conventional confines of traditional reverse osmosis membrane innovation through two groundbreaking advancements:
Revolutionary Ultra-Thin Separation Layer: Through the ingenious application of polymer interface nanotechnology, our team has impressively diminished the thickness of the separation layer to a mere third of the standard polyamide thin film (previously capped at 100 nm). This pioneering achievement dramatically amplifies water flux, ensuring a remarkable leap in permeability.
Superior Performance Enhancement: The strategic inclusion of nanoparticles and advanced hydrophilic polymers has catalyzed unprecedented enhancements in the membrane's hydrophilicity, anti-fouling capacity, durability, and oxidation resilience.
Compared to the conventional polyamide reverse osmosis membranes, Prosharehas achieved groundbreaking advancements across four essential dimensions:
Innovative Self-Assembled Nanocomposite Films
The fusion of nano-scale precision control with nano-doping innovation facilitates the creation of ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This innovative strategy transcends the constraints of traditional polyamide membranes concerning thickness consistency and material versatility.
Augmented Water Flux and Energy Efficiency
By refining the layer-by-layer self-assembly process, we precisely govern the functional layer thickness, achieving a remarkable 3x reduction compared to traditional membranes. This evolution results in over 3x higher water flux and a 30% reduction in energy consumption,culminating in unparalleled efficiency.
Avant-garde Polymer Materials with Exceptional Chemical Stability
Progressing beyond the limitations of polyamide, our team adopts advanced hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These cutting-edge materials exhibit outstanding oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH resilience (maintaining stability across a 1-12 pH range).
Pioneering Anti-Fouling Surface Engineering
