Proshare Team's Pioneering Breakthrough in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our team has expertly crafted an innovative new generation of reverse osmosis membranes, utilizing groundbreaking polymer interface nano-self-assembly technology. This remarkable innovation shatters the traditional limitations of reverse osmosis membrane development through two pivotal advancements:
Revolutionary Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, our team has achieved an impressive reduction in the separation layer thickness, making it at least three times thinner than the conventional polyamide thin film (previously constrained to 100 nm). This extraordinary breakthrough dramatically enhances water flux, leading to substantial improvements in permeability.
Unprecedented Enhanced Performance: The groundbreaking introduction of nanoparticles and specialized hydrophilic polymers has ushered in exceptional advancements in the membrane's hydrophilicity, anti-fouling capability, and robustness, alongside enhanced durability and oxidation resistance.
When compared to traditional polyamide reverse osmosis membranes, Proshare's revolutionary innovation showcases breakthroughs in four critical areas:
Self-Assembled Nanocomposite Films for Superior Performance
By integrating nano-scale precision control and nano-doping modification, we create ultra-thin, highly ordered separation layers through the pioneering use of polymer interface nanotechnology. This cutting-edge approach surpasses the limitations of conventional polyamide membranes in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Remarkable Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, the functional layer thickness is expertly controlled, achieving a threefold reduction compared to traditional membranes. This leads to over three times higher water flux and a remarkable 30% reduction in energy consumption.
Innovative Polymer Materials with Superior Chemical Stability
Going beyond polyamide, we utilize advanced hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These extraordinary materials exhibit exceptional resistance to oxidation (capable of withstanding exposure to 10 ppm chlorine) and impressive pH tolerance (maintaining stability across a broad pH range of 1 to 12).
Advanced Anti-Fouling Surface Engineering
The remarkable superhydrophilic surface (contact angle less than 10°), reinforced with nanoparticles, significantly reduces organic fouling propensity by 50%. This exceptional feature extends chemical cleaning cycles from three months to six months, and reduces maintenance costs by a substantial 40%.
