Our Advantages

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our pioneering team has ingeniously crafted a cutting-edge generation of reverse osmosis membranes utilizing the revolutionary polymer interface nano-self-assembly technology, triumphing over the constraints of conventional reverse osmosis membrane development with two remarkable advancements:
Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, our visionary team has successfully achieved a remarkable reduction in the separation layer's thickness, rendering it at least three times thinner than the conventional polyamide thin film, previously restricted to 100 nm. This phenomenal breakthrough significantly elevates water flux, yielding a substantial enhancement in permeability.
Enhanced Performance: By integrating cutting-edge nanoparticles and specialized hydrophilic polymers, we have pioneered groundbreaking enhancements in the membrane's hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance.
Compared to the traditional polyamide reverse osmosis membranes, Proshare's innovation showcases remarkable breakthroughs in four pivotal aspects:
Self-Assembled Nanocomposite Films
Through the seamless integration of nano-scale precision control and nano-doping modification, we have crafted ultra-thin, highly ordered separation layers using advanced polymer interface nanotechnology. This innovative approach transcends the limitations of conventional polyamide membranes in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By fine-tuning the layer-by-layer self-assembly process, we have precisely controlled the functional layer thickness, achieving a staggering 3x reduction compared to traditional membranes. This leads to more than 3x higher water flux and a 30% reduction in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Venturing beyond the conventional polyamide, we employ advanced hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These innovative materials demonstrate outstanding oxidation resistance (withstanding 10 ppm chlorine exposure) and pH tolerance (maintaining stability within the 1-12 pH range).
Anti-Fouling Surface Engineering
The superhydrophilic surface, with a contact angle less than 10°, combined with nanoparticle reinforcement, significantly reduces the propensity for organic fouling by 50%, extending chemical cleaning cycles from 3 months to an impressive 6 months, while slashing maintenance costs by a remarkable 40%.
