Our Advantages

Proshare Pioneering Breakthroughs in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our team has ingeniously pioneered a revolutionary generation of reverse osmosis membranes, utilizing advanced polymer interface nano-self-assembly technology. This innovative approach has triumphantly surpassed the constraints faced by traditional reverse osmosis membrane development, delivering two pivotal advancements:
Breakthrough in Ultra-Thin Separation Layer: By incorporating state-of-the-art polymer interface nanotechnology, our team has achieved an extraordinary reduction in the separation layer's thickness, now at least three times thinner compared to the conventional polyamide thin film (historically limited to 100 nm). This remarkable achievement not only significantly boosts water flux but also markedly enhances permeability.
Unprecedented Enhanced Performance: The infusion of cutting-edge nanoparticles combined with uniquely specialized hydrophilic polymers has propelled the membrane's performance to new heights, significantly enhancing its hydrophilicity, anti-fouling capabilities, durability, and resistance to oxidation.
In stark contrast to traditional polyamide reverse osmosis membranes, Proshare's groundbreaking innovation sets new standards in four critical dimensions:
Revolutionary Self-Assembled Nanocomposite Films
Through the precise integration of nano-scale control and nano-doping modification, we create ultra-thin, meticulously ordered separation layers using polymer interface nanotechnology. This strategic approach effectively overcomes the conventional polyamide membranes' challenges in achieving uniform thickness and diverse material applications.
Outstanding Enhanced Water Flux and Energy Efficiency
By skillfully optimizing the layer-by-layer self-assembly process, we achieve precise control over the functional layer thickness, successfully reducing it by 3x compared to conventional membranes, resulting in more than 3x increase in water flux and a remarkable 30% reduction in energy consumption.
Innovative Polymer Materials Offering Superior Chemical Stability
Beyond the limitations of polyamide, our team employs advanced hydrophilic polymers, such as modified polysulfones, along with ceramic-organic hybrids. These cutting-edge materials showcase exceptional resistance to oxidation (capable of withstanding exposure to 10 ppm chlorine) and impressive pH tolerance (remaining stable across a pH range of 1-12).
Innovative Anti-Fouling Surface Engineering
The integration of a superhydrophilic surface (with a contact angle of less than 10°), reinforced by nanoparticle inclusion, remarkably reduces organic fouling potential by 50%, effectively extending chemical cleaning cycles from 3 months to 6 months and achieving a 40% reduction in maintenance costs.
