Our Advantages

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team has boldly ventured into new frontiers, crafting a revolutionary generation of reverse osmosis membranes. Through the ingenious application of polymer interface nano-self-assembly technology, we've surpassed the conventional limitations of traditional membrane development by achieving two groundbreaking advancements:
Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, our team has dramatically reduced the thickness of the separation layer, making it at least three times thinner than the conventional 100 nm polyamide thin films. This pioneering achievement significantly elevates water flux, leading to a notable enhancement in permeability.
Enhanced Performance: With the infusion of nanoparticles and advanced hydrophilic polymers, we've leaped forward in improving the membrane's hydrophilicity, anti-fouling properties, robustness, and resistance to oxidation. These advancements represent a remarkable stride in membrane technology.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation delivers transformative breakthroughs in four vital areas:
Self-Assembled Nanocomposite Films
By integrating nano-scale precision and nano-doping technology, we craft ultra-thin, highly ordered separation layers through cutting-edge polymer interface nanotechnology. This innovative approach overcomes the barriers of conventional polyamide membranes, improving thickness uniformity and expanding material diversity.
Enhanced Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, we've achieved precise thickness control of the functional layer, resulting in a threefold reduction compared to traditional membranes. The outcome is a remarkable >3x higher water flux and a 30% reduction in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Beyond traditional polyamide, we employ advanced hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These materials showcase extraordinary resistance to oxidation (withstanding 10 ppm chlorine exposure) and superior pH tolerance (remarkably stable across a 1-12 pH range).
Advanced Anti-Fouling Surface Engineering
Our superhydrophilic surface, with a contact angle of less than 10°, is reinforced with nanoparticles, reducing organic fouling by an impressive 50%. This innovation extends chemical cleaning cycles from 3 to 6 months, significantly cutting maintenance costs by 40%.
