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 cutting-edge polymer interface nanotechnology, the team has masterfully reduced the thickness of the separation layer to at least three times thinner than traditional polyamide thin films (previously constrained to 100 nm). This remarkable breakthrough significantly elevates water flux, achieving a substantial leap in permeability.
Enhanced Performance: The strategic introduction of nanoparticles coupled with specialized hydrophilic polymers has pioneered groundbreaking enhancements in the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance, setting new standards in the industry.
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 empowers the creation of ultra-thin, highly ordered separation layers via state-of-the-art polymer interface nanotechnology. This innovative approach triumphs over the limitations of conventional polyamide membranes in thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By perfecting the layer-by-layer self-assembly process, the functional layer thickness is meticulously controlled, achieving a dramatic 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 the confines of polyamide, the team utilizes advanced hydrophilic polymers (e.g., modified polysulfones) and cutting-edge ceramic-organic hybrids. These materials exhibit exceptional oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH tolerance (stable across a wide pH range of 1-12).
Anti-Fouling Surface Engineering
The superhydrophilic surface (contact angle <10°), reinforced with nanoparticles, dramatically reduces organic fouling propensity by 50%, thereby extending chemical cleaning cycles from 3 months to 6 months and slashing maintenance costs by 40%
