Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare The Proshare team has embarked on a pioneering journey to elevate reverse osmosis membranes to new heights of innovation. By harnessing the power of polymer interface nano-self-assembly technology, we have transcended the conventional barriers of membrane development, achieving two monumental advancements:
Ultra-Thin Separation Layer: Utilizing cutting-edge polymer interface nanotechnology, our team has masterfully reduced the separation layer's thickness, achieving a staggering reduction of at least three times thinner than standard polyamide films, which were previously constrained to 100 nm. This remarkable innovation amplifies water flux, delivering a dramatic leap in permeability.
Enhanced Performance: Through the strategic integration of nanoparticles and advanced hydrophilic polymers, we have unlocked groundbreaking enhancements in the membrane's hydrophilicity, alongside superior anti-fouling capabilities, enhanced durability, and increased oxidation resistance.
In comparison to traditional polyamide reverse osmosis membranes, Proshare's innovation heralds breakthroughs across four pivotal dimensions:
Self-Assembled Nanocomposite Films
By ingeniously combining nano-scale precision control with nano-doping modification, we revolutionize the creation of ultra-thin, impeccably ordered separation layers through polymer interface nanotechnology. This innovative strategy transcends the limitations of conventional polyamide membranes, achieving unparalleled uniformity in thickness and expanding material diversity.
Enhanced Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, we achieve precise control over the functional layer thickness, culminating in a remarkable 3x reduction compared to traditional membranes, thereby resulting in water flux that is over three times higher and a substantial 30% reduction in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Advancing beyond traditional polyamide, our team employs cutting-edge hydrophilic polymers, such as modified polysulfones, and innovative ceramic-organic hybrids. These materials demonstrate exceptional oxidation resistance, capable of enduring up to 10 ppm chlorine exposure, and exhibit superior pH tolerance, remaining stable across a wide pH range from 1 to 12.
Anti-Fouling Surface Engineering
Leveraging a superhydrophilic surface characterized by a contact angle of less than 10°, along with nanoparticle reinforcement, we significantly diminish organic fouling propensity by 50%, extending chemical cleaning cycles from 3 to 6 months and achieving a remarkable 40% reduction in maintenance costs.
