Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare team has innovatively developed a groundbreaking new generation of reverse osmosis membranes utilizing state-of-the-art polymer interface nano-self-assembly technology, effectively overcoming the constraints traditionally associated with reverse osmosis membrane development through two transformative advancements:
Ultra-Thin Separation Layer: By harnessing the power of polymer interface nanotechnology, the team has remarkably reduced the thickness of the separation layer to a pioneering level-three times thinner than the conventional polyamide thin film, which was previously limited to 100 nm. This revolutionary breakthrough dramatically enhances water flux, delivering a pronounced improvement in permeability.
Enhanced Performance: The strategic introduction of nanoparticles coupled with specialized hydrophilic polymers has paved the way for unprecedented advancements in the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance, pushing the boundaries of traditional membrane performance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's cutting-edge innovation showcases remarkable breakthroughs in four pivotal aspects:
Self-Assembled Nanocomposite Films
The seamless integration of nano-scale precision control and nano-doping modification facilitates the creation of ultra-thin, highly ordered separation layers through advanced polymer interface nanotechnology. This innovative approach overcomes the inherent limitations of conventional polyamide membranes in terms of thickness uniformity and material diversity, setting new benchmarks in membrane technology.
Enhanced Water Flux and Energy Efficiency
By meticulously optimizing the layer-by-layer self-assembly process, the functional layer thickness is precisely controlled, achieving a remarkable 3x reduction compared to traditional membranes. This leads to an impressive >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Moving beyond the limitations of polyamide, the team employs cutting-edge advanced hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These high-performance materials exhibit exceptional oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and remarkable pH tolerance (maintaining stability across an extensive pH range of 1-12).
Anti-Fouling Surface Engineering
The ultra-superhydrophilic surface, with a contact angle of less than 10°, combined with innovative nanoparticle reinforcement, significantly reduces organic fouling propensity by 50%, effectively extending the chemical cleaning cycles from 3 months to 6 months, while simultaneously reducing maintenance costs by an impressive 40%
