Proshare Team's Pioneering Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team has ingeniously developed a cutting-edge generation of reverse osmosis membranes leveraging polymer interface nano-self-assembly technology. This pioneering approach has allowed us to transcend the traditional limitations in reverse osmosis membrane development, achieving two monumental advancements:
a. Ultra-Thin Separation Layer: Through the innovative use of polymer interface nanotechnology, we have remarkably reduced the thickness of the separation layer, achieving a layer at least thrice as thin as the conventional polyamide thin film, which was previously restricted to 100 nm. This significant breakthrough markedly enhances water flux, resulting in substantial improvements in permeability and overall performance.
b. Enhanced Performance: By introducing nanoparticles alongside specialized hydrophilic polymers, we have achieved groundbreaking advancements in the membrane's hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance, setting new standards in membrane performance.
In contrast to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases breakthroughs across four pivotal aspects:
Self-Assembled Nanocomposite Films
With precise nano-scale control and nano-doping modifications, our self-assembly process creates ultra-thin, highly organized separation layers through polymer interface nanotechnology. This approach overcomes the traditional constraints in polyamide membranes related to uniformity in thickness and diversity of materials.
Enhanced Water Flux and Unmatched Energy Efficiency
By perfecting the layer-by-layer self-assembly process, we precisely control the thickness of the functional layer, reducing it to one-third of that of traditional membranes. This results in more than 3x greater water flux and a remarkable 30% reduction in energy consumption,leading to unparalleled efficiency.
Innovative Polymer Materials with Exceptional Chemical Stability
Breaking free from polyamide, we employ cutting-edge hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These advanced materials offer exceptional resistance to oxidation (withstanding exposure to 10 ppm chlorine) and remarkable pH tolerance (remaining stable across a wide pH range of 1-12).
Revolutionary Anti-Fouling Surface Engineering
Our superhydrophilic surface, with a contact angle of less than 10°, reinforced by nanoparticle integration, dramatically reduces the propensity for organic fouling by 50%. This extends the chemical cleaning cycle from 3 months to an impressive 6 months while slashing maintenance costs by 40%.
