Proshare Team's Groundbreaking Achievements in Advanced Reverse Osmosis Membrane Technology
Proshare Our team has ingeniously crafted a novel generation of reverse osmosis membranes utilizing cutting-edge polymer interface nano-self-assembly technology. This remarkable innovation transcends the constraints of conventional reverse osmosis membrane development by pioneering two critical advancements:
Revolutionary Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, the team has achieved an unprecedented reduction in the separation layer's thickness, making it at least three times thinner than the existing polyamide films, previously restricted to 100 nm. This breakthrough drastically improves water flux, leading to a remarkable enhancement in permeability.
Superior Performance Enhancement: Through the introduction of nanoparticles and exclusive hydrophilic polymers, the membrane now boasts unparalleled advancements in hydrophilicity, anti-fouling properties, durability, and resistance to oxidation.
In comparison to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases transformative breakthroughs in four pivotal areas:
Self-Assembled Nanocomposite Films
Utilizing nano-scale precision control alongside nano-doping modifications, this technique creates ultra-thin, meticulously ordered separation layers with polymer interface nanotechnology. This innovative approach overcomes the challenges of conventional polyamide membranes concerning thickness uniformity and material diversity.
Enhanced Water Flux and Optimized Energy Efficiency
By refining the layer-by-layer self-assembly process, we've precisely controlled the functional layer's thickness, achieving a 3x reduction compared to traditional membranes. This accomplishment results in >3x higher water flux and 30% lower energy consumption.
Innovative Polymer Materials with Exceptional Chemical Durability
Surpassing polyamide, our team incorporates avant-garde hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids, showcasing outstanding oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (maintaining stability across a 1-12 pH range).
