Proshare Pioneering Breakthrough in Revolutionary Reverse Osmosis Membrane Technology by Our Team
Proshare Our dedicated team at Proshare has ingeniously crafted a cutting-edge generation of reverse osmosis membranes utilizing state-of-the-art polymer interface nano-self-assembly technology. By surmounting the inherent challenges of traditional methods, we've achieved two pivotal advancements that redefine membrane innovation:
Ultra-Thin Separation Layer: With the application of advanced polymer interface nanotechnology, our team has ingeniously minimized the separation layer's thickness to a remarkable degree, rendering it at least three times thinner than the conventional 100 nm polyamide thin film. This revolutionary accomplishment notably amplifies water flux and markedly enhances permeability efficiency.
Unprecedented Performance Enhancement: By incorporating nanoparticles and specialized hydrophilic polymers, we have achieved transformative advancements in the membrane's properties, including heightened hydrophilicity, enhanced anti-fouling capabilities, superior durability, and outstanding oxidation resistance.
When juxtaposed with traditional polyamide reverse osmosis membranes, Proshare's innovation showcases cutting-edge breakthroughs in these four critical dimensions:
Self-Assembled Nanocomposite Films
Through precision nano-scale control and nano-doping modification, we have mastered the ability to create ultra-thin, meticulously ordered separation layers using polymer interface nanotechnology. This formidable approach transcends the conventional limitations of polyamide membranes concerning thickness uniformity and material versatility.
Amplified Water Flux and Energy Efficiency
By meticulously optimizing the layer-by-layer self-assembly process, we have precisely calibrated the functional layer's thickness, achieving a remarkable threefold reduction compared to traditional membranes. This optimization culminates in >3x amplified water flux accompanied by an impressive 30% reduction in energy consumption.
Innovative Polymer Materials with Unequalled Chemical Stability
Beyond the conventional polyamide, our team has ventured into utilizing advanced hydrophilic polymers, such as modified polysulfones, alongside ceramic-organic hybrid materials. These superior materials demonstrate exemplary oxidation resistance (withstanding exposure to 10 ppm chlorine) and remarkable pH resilience (maintaining stability across a pH range of 1-12).
