Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare team has innovatively developed a new generation of reverse osmosis membranes based on polymer interface nano-self-assembly technology, overcoming the limitations of traditional reverse osmosis membrane development through two key advancements:
Ultra-Thin Separation Layer: By employing polymer interface nanotechnology, the team successfully reduced the thickness of the separation layer to at least three times thinner than the traditional polyamide thin film (previously limited to 100 nm). This breakthrough significantly enhances water flux, achieving a substantial improvement in permeability.
Enhanced Performance: The introduction of nanoparticles and specialized hydrophilic polymers has led to groundbreaking advancements in the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation demonstrates breakthroughs in four key aspects:
Self-Assembled Nanocomposite Films
The integration of nano-scale precision control and nano-doping modification enables the creation of ultra-thin, highly ordered separation layers via polymer interface nanotechnology. This approach overcomes the limitations of conventional polyamide membranes in thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By optimizing the layer-by-layer self-assembly process, the functional layer thickness is precisely controlled, achieving a 3x reduction compared to traditional membranes. This results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Moving beyond polyamide, the team utilizes advanced hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These materials exhibit exceptional oxidation resistance (withstand 10 ppm chlorine exposure) and pH tolerance (stable in 1-12 pH range).
Anti-Fouling Surface Engineering
The superhydrophilic surface (contact angle <10°) combined with nanoparticle reinforcement reduces organic fouling propensity by 50%, extending chemical cleaning cycles from 3 months to 6 months and cutting maintenance costs by 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.
Technological Innovation: Pioneered the application of TFN technology to nanofiltration membranes, achieving fully independent R&D and localized production of both membranes and manufacturing equipment.
Intellectual Property: Holds over 31 patents, with membrane performance reaching internationally leading standards and replacing monopolized foreign products.
Production Capacity: Operates a 2,000 m² R&D facility and a 15,000 m² production base.
Funding: Completed Pre-A Round (2023) and A Round (January 2025) financing, backed by Suzhou Industrial Park Science Innovation Fund and Yong Sheng Capital.
Market Recognition: Designated as a preferred supplier for listed environmental engineering firms and state-owned enterprises.
Leadership:Dr. Lin Xiaofeng, a Ph.D. graduate from the University of Strasbourg (France), has been recognized with provincial and national talent awards (e.g., Suzhou Leading Talent, Jiangsu Dual Innovation Talent) and leads the company's R&D breakthroughs in TFN membrane industrialization.
