Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our dedicated team has pioneered the development of a revolutionary new generation of reverse osmosis membranes, ingeniously utilizing cutting-edge polymer interface nano-self-assembly technology. By surpassing traditional reverse osmosis membrane limitations, we've achieved remarkable advancements in two pivotal areas:
Ultra-Thin Separation Layer: Leveraging state-of-the-art polymer interface nanotechnology, our team has achieved an extraordinary feat by making the separation layer at least three times thinner than the conventional polyamide thin film, which was previously constrained to 100 nm. This remarkable innovation substantially boosts water flux, delivering a significant leap in permeability.
Enhanced Performance: The infusion of nanoparticles alongside specialized hydrophilic polymers has spearheaded groundbreaking enhancements in the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance, setting new standards in membrane technology.
In comparison to traditional polyamide reverse osmosis membranes, Proshare's innovation represents breakthroughs in four crucial aspects:
Self-Assembled Nanocomposite Films
Through the integration of nano-scale precision control and nano-doping modification, we create ultra-thin, highly organized separation layers using advanced polymer interface nanotechnology. This sophisticated approach overcomes conventional polyamide membranes' limitations in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Our meticulous optimization of the layer-by-layer self-assembly process allows precise control over the functional layer thickness, achieving a reduction three times that of conventional membranes. This precision translates into >3x higher water flux and 30% lower energy consumption.
Innovative Polymer Materials with Superior Chemical Stability
Moving beyond the confines of polyamide, our team employs cutting-edge hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids, which showcase exceptional oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (remaining stable across a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
Our superhydrophilic surface (with a contact angle of <10°), reinforced with nanoparticles, significantly reduces organic fouling propensity by 50%, extending chemical cleaning intervals from 3 months to 6 months, and slashing maintenance costs by an impressive 40%.
Our unwavering dedication to quality and safety is reflected in our prestigious certifications: the Health & Safety Management System Certificate, the Environmental Management System Certificate, and the esteemed ISO9001 Quality System Certificate, all of which stand as testaments to our commitment to excellence.
