Proshare Trailblazing Team Achieves a Breakthrough in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare has revolutionized the field with its cutting-edge development of a new generation of reverse osmosis membranes, utilizing pioneering polymer interface nano-self-assembly technology. This remarkable progress surpasses conventional membrane limitations through two pivotal advancements:
Ultra-Thin Separation Layer: By harnessing the power of polymer interface nanotechnology, Proshare's team has masterfully achieved a leap in reducing the separation layer's thickness to an unprecedented level, at least three times slimmer than the traditional polyamide thin film, which was previously restricted to 100 nm. This game-changing innovation significantly boosts water flux, marking a major leap forward in permeability.
Enhanced Performance: The groundbreaking introduction of nanoparticles alongside specialized hydrophilic polymers has propelled the membrane's hydrophilicity, anti-fouling capacity, durability, and oxidation resistance to new heights.
When compared to conventional polyamide reverse osmosis membranes, Proshare's innovative approach showcases pioneering advancements across four crucial dimensions:
Self-Assembled Nanocomposite Films
The fusion of nano-scale precision and nano-doping modification paves the way for creating ultra-thin, impeccably ordered separation layers using polymer interface nanotechnology. This breakthrough transcends the constraints of traditional polyamide membranes in terms of thickness uniformity and material versatility.
Boosted Water Flux and Superior Energy Efficiency
Through the meticulous refinement of the layer-by-layer self-assembly process, the functional layer's thickness is precisely reduced, accomplishing a threefold reduction compared to traditional membranes. This pioneering approach results in a >3x augmentation in water flux paired with a 30% decrease in energy consumption.
Innovative Polymer Materials with Remarkable Chemical Resilience
Venturing beyond polyamide, the team employs avant-garde hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These superior materials exhibit outstanding resistance to oxidation (capable of enduring 10 ppm chlorine exposure) and wide-ranging pH stability (maintaining stability across a pH range of 1-12).
Cutting-Edge Anti-Fouling Surface Engineering
The ultra-hydrophilic surface, with a contact angle of less than 10°, combined with nanoparticle reinforcement, reduces organic fouling potential by 50%. This extends chemical cleaning intervals from 3 to 6 months, ultimately reducing maintenance costs by 40%.
