Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare The Proshare team has ingeniously developed a groundbreaking new generation of reverse osmosis membranes, leveraging cutting-edge polymer interface nano-self-assembly technology. This revolutionary approach addresses the limitations inherent in traditional reverse osmosis membrane development, achieving two monumental advancements:
a. Ultra-Thin Separation Layer: Through the innovative application of polymer interface nanotechnology, the Proshare team has achieved a remarkable reduction in the thickness of the separation layer, making it at least three times thinner than conventional polyamide thin films (previously constrained to 100 nm). This pioneering advance significantly amplifies water flux, yielding a substantial enhancement in permeability and performance.
b. Enhanced Performance: The strategic introduction of nanoparticles and specialized hydrophilic polymers has ushered in transformative improvements in the membrane's hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance, setting a new standard in membrane efficiency and longevity.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovative design exhibits groundbreaking advancements across four critical aspects:
Self-Assembled Nanocomposite Films
By adeptly integrating nano-scale precision control with nano-doping modification, Proshare has crafted ultra-thin and highly ordered separation layers through polymer interface nanotechnology. This advanced methodology surmounts the limitations of conventional polyamide membranes in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, the thickness of the functional layer is precisely controlled, achieving a threefold reduction compared to traditional membranes. This innovation results in >3x higher water flux and a 30% reduction in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Proshare transcends conventional polyamide by utilizing state-of-the-art hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These avant-garde materials exhibit unparalleled oxidation resistance (withstanding 10 ppm chlorine exposure) and exceptional pH tolerance (remaining stable across a pH range of 1-12).
Anti-Fouling Surface Engineering
With a superhydrophilic surface (contact angle <10°) reinforced by nanoparticles, Proshare's membranes significantly reduce organic fouling propensity by 50%, thereby extending chemical cleaning cycles from 3 months to 6 months and slashing maintenance costs by an impressive 40%
Proshare Innovation Suzhou Co., Ltd. is a national high-tech enterprise specializing in the R&D and industrialization of third-generation thin-film nanocomposite (TFN) membranes for reverse osmosis (RO), nanofiltration (NF), and material separation applications. Founded in 2017 by a team of overseas-returned doctoral experts led by Dr. Lin Xiaofeng, a recipient of national-level talent programs, the company has emerged as China's sole domestic manufacturer of TFN membranes.
