Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our pioneering team has masterfully crafted a revolutionary generation of reverse osmosis membranes utilizing cutting-edge polymer interface nano-self-assembly technology. By overcoming traditional development constraints with two monumental advancements, we have redefined the potential of membrane technology:
a. Ultra-Thin Separation Layer: Through the innovative application of polymer interface nanotechnology, our team has successfully minimized the thickness of the separation layer to an unprecedented thinness, making it at least three times more slender than the conventional polyamide thin film, which was previously constrained to 100 nm. This remarkable achievement significantly boosts water flux, culminating in a substantial enhancement of permeability.
b. Enhanced Performance: With the strategic incorporation of nanoparticles and specialized hydrophilic polymers, the membrane has achieved transformative advancements in its hydrophilicity, anti-fouling capability, durability, and oxidation resistance, setting a new benchmark in membrane efficiency and longevity.
In contrast to traditional polyamide reverse osmosis membranes, Proshare's groundbreaking innovation showcases unparalleled advancements across four critical dimensions:
Self-Assembled Nanocomposite Films
By harnessing nano-scale precision control and nano-doping modification, we create ultra-thin, highly organized separation layers via polymer interface nanotechnology. This innovation transcends the limitations of conventional polyamide membranes, vastly improving thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, we precisely control the functional layer thickness, achieving a remarkable 3x reduction compared to traditional membranes. The outcome is a tremendous >3x increase in water flux accompanied by an impressive 30% reduction in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Venturing beyond polyamide, our team employs advanced hydrophilic polymers, such as modified polysulfones, alongside ceramic-organic hybrids. These cutting-edge materials display extraordinary oxidation resistance (enduring 10 ppm chlorine exposure) and pH tolerance (maintaining stability across a pH range of 1-12).
Anti-Fouling Surface Engineering
The creation of a superhydrophilic surface (with a contact angle of less than 10°) reinforced with nanoparticles dramatically reduces organic fouling by 50%. This innovation effectively doubles the duration of chemical cleaning cycles from 3 months to 6 months, resulting in a 40% reduction in maintenance costs.
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.
