Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team has ingeniously pioneered a new generation of reverse osmosis membranes utilizing groundbreaking polymer interface nano-self-assembly technology. By overcoming the constraints faced by traditional reverse osmosis membranes, we have achieved two pivotal advancements:
Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, we've achieved a remarkable reduction in the separation layer's thickness, making it at least three times thinner than conventional polyamide thin films, which were previously constrained to 100 nm. This significant leap forward dramatically enhances water flow, resulting in a striking improvement in permeability.
Enhanced Performance: Innovative use of nanoparticles and advanced hydrophilic polymers has led to trailblazing enhancements in the membrane's hydrophilicity, anti-fouling properties, durability, and resistance to oxidation.
In contrast to traditional polyamide reverse osmosis membranes, Proshare's innovation sets new standards by achieving breakthroughs in four crucial areas:
Self-Assembled Nanocomposite Films
Through the integration of nano-scale precision control and nano-doping modifications, we craft ultra-thin, highly ordered separation layers via polymer interface nanotechnology. This method transcends conventional polyamide membrane limitations in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Our optimization of the layer-by-layer self-assembly process precisely controls functional layer thickness, resulting in a remarkable 3x reduction compared to traditional membranes. This achievement culminates in >3x higher water flux and 30% reduced energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Venturing beyond polyamide, our team employs advanced hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These materials stand out for their extraordinary oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH stability (remaining stable across a pH range of 1-12).
Anti-Fouling Surface Engineering
Our superhydrophilic surfaces, with a contact angle of less than 10°, combined with nanoparticle reinforcement, reduce the tendency for organic fouling by 50%. This advancement extends chemical cleaning cycles from 3 to 6 months and slashes maintenance costs by 40%.
