Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our dedicated team has ingeniously pioneered a revolutionary new generation of reverse osmosis membranes, powered by cutting-edge polymer interface nano-self-assembly technology. This innovative leap forward transcends the conventional constraints of traditional membrane development through two pivotal advancements:
Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, our team has achieved a phenomenal reduction in the thickness of the separation layer, making it at least three times thinner than the conventional polyamide thin film, which was previously capped at 100 nm. This pivotal breakthrough not only elevates water flux but also marks a substantial enhancement in permeability.
Enhanced Performance: By integrating nanoparticles and specialized hydrophilic polymers, we have propelled the membrane's performance to new heights, achieving remarkable advancements in hydrophilicity, anti-fouling capability, durability, and oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases transformative breakthroughs across four critical dimensions:
Self-Assembled Nanocomposite Films
Through the fusion of nano-scale precision control and nano-doping modification, we craft ultra-thin, impeccably ordered separation layers utilizing polymer interface nanotechnology. This methodology triumphs over the limitations of conventional polyamide membranes in achieving thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By meticulously optimizing the layer-by-layer self-assembly process, we achieve precise control over functional layer thickness, culminating in a remarkable 3x reduction compared to traditional membranes. This leads to >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Surpassing the polyamide frontier, our team employs advanced hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These state-of-the-art materials boast extraordinary oxidation resistance (capable of withstanding exposure to 10 ppm chlorine) and pH tolerance (standing resilient within a pH range of 1-12).
Anti-Fouling Surface Engineering
The integration of a superhydrophilic surface (contact angle <10°) with nanoparticle reinforcement significantly diminishes organic fouling tendencies by 50%, extending chemical cleaning cycles from 3 months to 6 months, thereby reducing maintenance costs by 40%.
Our unwavering commitment to excellence is underscored by our prestigious certifications, which include the Health & Safety Management System Certificate, Environmental Management System Certificate, and the esteemed ISO9001 Quality System Certificate.
