Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Through pioneering advancements in polymer interface nano-self-assembly technology, our Proshare team has ingeniously developed a new generation of reverse osmosis membranes. This revolutionary approach has successfully surpassed the hurdles of traditional reverse osmosis membrane development, showcasing two pivotal innovations:
Ultra-Thin Separation Layer: Leveraging cutting-edge polymer interface nanotechnology, our team has achieved an unprecedented reduction in the separation layer's thickness, making it at least three times thinner than the standard polyamide thin film, which until now was restricted to 100 nm. This remarkable breakthrough not only augments water flux but also substantially boosts permeability, marking a significant leap forward in membrane efficiency.
Enhanced Performance: By integrating nanoparticles and crafting specialized hydrophilic polymers, we've attained unprecedented strides in membrane performance. These enhancements improve the hydrophilicity, bolster anti-fouling capabilities, and elevate the membrane's durability and resistance to oxidation.
Compared to traditional polyamide reverse osmosis membranes, Proshare's groundbreaking innovation shines with breakthroughs in four crucial aspects:
Self-Assembled Nanocomposite Films
By amalgamating nano-scale precision control with nano-doping modification, we have pioneered the creation of ultra-thin, meticulously ordered separation layers via advanced polymer interface nanotechnology. This method circumvents the constraints of conventional polyamide membranes, particularly in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, we have precisely controlled the functional layer thickness, achieving a dramatic 3x reduction compared to traditional membranes. This advancement culminates in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Beyond the limitations of polyamide, our team employs advanced, hydrophilic polymers such as modified polysulfones and ceramic-organic hybrids. These innovative materials boast exceptional oxidation resistance (withstanding 10 ppm chlorine exposure) and remarkable pH tolerance (remaining stable across a wide 1-12 pH range).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, with a contact angle of less than 10°, combined with nanoparticle reinforcement, significantly reduces the propensity for organic fouling by 50%. This innovation extends chemical cleaning cycles from 3 to 6 months and slashes maintenance costs by 40%, enhancing overall operational efficiency and longevity.
