Our Advantages

Proshare Team's Pioneering Breakthrough in Revolutionary Reverse Osmosis Membrane Technology
Proshare Our innovative team has masterfully developed a cutting-edge generation of reverse osmosis membranes, ingeniously utilizing polymer interface nano-self-assembly technology. This remarkable achievement triumphs over the traditional reverse osmosis barriers through two pivotal advancements:
Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, our team has astoundingly reduced the separation layer's thickness to a groundbreaking threefold reduction compared to the conventional polyamide thin film (previously capped at 100 nm). This remarkable development dramatically boosts water flux, catapulting permeability to new heights.
Elevated Performance: Thanks to the strategic incorporation of nanoparticles and tailor-made hydrophilic polymers, we have achieved unparalleled advancements in the membrane's hydrophilicity, anti-fouling prowess, robustness, and resilience against oxidation.
When put side-by-side with traditional polyamide reverse osmosis membranes, Proshare's stellar innovation showcases breakthroughs across four essential dimensions:
Self-Assembled Nanocomposite Films
Seamlessly integrating nano-scale precision control and nano-doping modification, our approach crafts ultra-thin, meticulously ordered separation layers via cutting-edge polymer interface nanotechnology. This strategy triumphs over conventional polyamide membranes, ensuring superior thickness uniformity and material versatility.
Enhanced Water Flux and Unmatched Energy Efficiency
Through meticulous refinement of the layer-by-layer self-assembly process, we achieve precise functional layer thickness control, boasting a remarkable 3x thinner layer compared to traditional membranes. This results in an impressive >3x enhancement in water flux while achieving a substantial 30% reduction in energy consumption.
Revolutionary Polymer Materials with Exceptional Chemical Stability
Pushing beyond the polyamide frontier, our team employs state-of-the-art hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These advanced materials deliver extraordinary oxidation resistance (withstanding 10 ppm chlorine exposure) along with unmatched pH stability (remaining stable across a broad pH range of 1-12).
Cutting-Edge Anti-Fouling Surface Engineering
The incorporation of a superhydrophilic surface (with a contact angle of <10°) combined with robust nanoparticle reinforcement effectively slashes organic fouling by an impressive 50%. This advancement extends chemical cleaning cycles from 3 to 6 months, significantly reducing maintenance costs by 40%.
