Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our expert team at Proshare has ingeniously pioneered a revolutionary new generation of reverse osmosis membranes by leveraging cutting-edge polymer interface nano-self-assembly technology. This remarkable development overcomes the traditional constraints of reverse osmosis membrane technology with two transformative advancements:
Ultra-Thin Separation Layer: Utilizing the sophisticated polymer interface nanotechnology, our team has impressively minimized the separation layer's thickness to an astounding level, making it at least three times thinner than the conventional 100 nm polyamide thin film. This breakthrough not only dramatically boosts water flux but also provides a major leap in permeability.
Enhanced Performance: Thanks to the integration of innovative nanoparticles and unique hydrophilic polymers, we have achieved remarkable enhancements in the membrane's hydrophilicity, anti-fouling capability, durability, and superior oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's groundbreaking innovation showcases significant advancements in four pivotal areas:
Self-Assembled Nanocomposite Films
By integrating nano-scale precision control with nano-doping modification, we have crafted ultra-thin, highly ordered separation layers using polymer interface nanotechnology. This pioneering approach surpasses the limitations of standard polyamide membranes in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through the 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, resulting in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Surpassing the boundaries of polyamide, our team employs advanced hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These materials showcase extraordinary oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (remaining stable across a wide 1-12 pH range).
Anti-Fouling Surface Engineering
Our ultra-hydrophilic surface, with a contact angle of less than 10°, combined with nanoparticle reinforcement, significantly reduces organic fouling by 50%, extending chemical cleaning intervals from 3 to 6 months and slashing maintenance expenses by 40%.
