Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare At Proshare, our pioneering team has masterfully crafted an innovative generation of reverse osmosis membranes by harnessing the power of polymer interface nano-self-assembly technology. This groundbreaking advancement transcends the limitations of traditional reverse osmosis membrane development with two pivotal breakthroughs:
Ultra-Thin Separation Layer: Our team has revolutionized the thickness of the separation layer by employing cutting-edge polymer interface nanotechnology, making it at least three times thinner than the conventional polyamide thin film, which was restricted to 100 nm. This monumental innovation significantly boosts water flux, leading to a substantial leap in permeability.
Enhanced Performance: Through the strategic integration of nanoparticles and specialized hydrophilic polymers, we have achieved groundbreaking progress in enhancing the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases breakthroughs in four critical areas:
Self-Assembled Nanocomposite Films
By seamlessly integrating nano-scale precision control with nano-doping modification, we have successfully developed ultra-thin, highly ordered separation layers through advanced polymer interface nanotechnology. This approach masterfully overcomes the challenges 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, we precisely control the functional layer thickness, resulting in a remarkable 3x reduction in comparison to traditional membranes. This breakthrough facilitates >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Breaking free from polyamide, our team expertly utilizes advanced hydrophilic polymers, such as modified polysulfones and ceramic-organic hybrids. These cutting-edge materials showcase exceptional oxidation resistance (withstanding 10 ppm chlorine exposure) and pH tolerance (remaining stable in the 1-12 pH range).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, featuring a contact angle of less than 10°, combined with nanoparticle reinforcement, reduces organic fouling propensity by 50%.
