Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our groundbreaking team has pioneered a new era of reverse osmosis membranes by ingeniously utilizing polymer interface nano-self-assembly technology. This revolutionary approach has shattered the barriers faced in the traditional development of reverse osmosis membranes, bringing forth two monumental advancements:
a. Ultra-Thin Separation Layer: With the mastery of polymer interface nanotechnology, we've achieved an unprecedented reduction in the separation layer's thickness, making it at least three times thinner than the standard polyamide thin film, previously capped at 100 nm. This exceptional innovation dramatically elevates water flux, resulting in a significant leap in permeability.
b. Enhanced Performance: The strategic incorporation of nanoparticles alongside specialized hydrophilic polymers has catapulted the membrane's hydrophilicity, anti-fouling prowess, durability, and oxidation resistance to new heights.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovative leap showcases breakthroughs across four pivotal dimensions:
Self-Assembled Nanocomposite Films
By expertly weaving nano-scale precision control with nano-doping modification, we craft ultra-thin, highly ordered separation layers through advanced polymer interface nanotechnology. This cutting-edge method surpasses the limitations of conventional polyamide membranes, achieving remarkable consistency in thickness and an expanded material diversity.
Enhanced Water Flux and Energy Efficiency
Through the meticulous optimization of the layer-by-layer self-assembly process, we precisely control the functional layer thickness, achieving a remarkable threefold reduction compared to traditional membranes. This precision engineering yields >3x higher water flux and a remarkable 30% reduction in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Venturing beyond conventional polyamide, our team employs advanced hydrophilic polymers, such as modified polysulfones, and innovative ceramic-organic hybrids. These materials boast exceptional oxidation resistance (withstanding exposure to 10 ppm chlorine) and robust pH tolerance (remaining stable across a wide pH spectrum of 1-12).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, with a contact angle of less than 10°, reinforced with nanoparticles, reduces organic fouling by 50%. This advancement extends chemical cleaning cycles from three to six months, slashing maintenance costs by an impressive 40%.
