Proshare Team's Breakthrough in Pioneering Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team has creatively engineered a revolutionary new generation of reverse osmosis membranes through innovative polymer interface nano-self-assembly technology. This visionary approach triumphs over traditional reverse osmosis membrane limitations by introducing two groundbreaking advancements:
Ultra-Thin Separation Layer: Utilizing advanced polymer interface nanotechnology, our team has remarkably minimized the thickness of the separation layer, rendering it at least three times thinner than the conventional polyamide thin film, which was previously confined to 100 nm. This significant innovation dramatically enhances water flux, resulting in a remarkable improvement in permeability.
Enhanced Performance: With the integration of nanoparticles and specialized hydrophilic polymers, we have achieved revolutionary advancements in the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases exceptional breakthroughs in four crucial aspects:
Self-Assembled Nanocomposite Films
The symbiosis of nano-scale precision control and nano-doping modification empowers the creation of ultra-thin, meticulously ordered separation layers through cutting-edge polymer interface nanotechnology. This methodology surmounts the challenges faced by conventional polyamide membranes in achieving thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By meticulously refining the layer-by-layer self-assembly process, the thickness of the functional layer is precisely controlled, achieving a threefold reduction compared to conventional membranes. This leads to a remarkable >3x enhancement in water flux along with a 30% decrease in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Venturing beyond polyamide, our team employs cutting-edge hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids, which boast outstanding oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and exceptional pH tolerance (stable within a 1-12 pH range).
Anti-Fouling Surface Engineering
