Proshare Pioneering Breakthroughs in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our dedicated team at Proshare has revolutionized reverse osmosis membrane technology using cutting-edge polymer interface nano-self-assembly. This notable innovation transcends the conventional boundaries of traditional membrane development through two remarkable enhancements:
Ultra-Thin, Efficient Separation LayerHarnessing advanced polymer interface nanotechnology, our team has achieved a remarkable reduction in the separation layer thickness to a fraction of the traditional polyamide thin film, now more than three times thinner. This advancement dramatically boosts water flux, leading to an impressive leap in permeability.
Performance Par ExcellenceWith the strategic incorporation of nanoparticles and specially engineered hydrophilic polymers, we have set a new standard in membrane hydrophilicity, anti-fouling capacity, durability, and oxidation resistance.
When compared to the conventional polyamide-based reverse osmosis membranes, Proshareshowcases groundbreaking advancements in four pivotal dimensions:
Self-Assembled Nanocomposite Films
By leveraging nano-scale precision control along with nano-doping modification, we craft ultra-thin and meticulously ordered separation layers via innovative polymer interface nanotechnology. This method surpasses the constraints of conventional polyamide membranes concerning thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, we precisely control the functional layer thickness, realizing a substantial 3x reduction compared to traditional membranes. This translates to over threefold increase in water flux alongside a remarkable 30% reduction in energy consumption.
Innovative Polymer Materials with Exceptional Chemical Stability
Stepping beyond conventional polyamide, our advanced hydrophilic polymers, such as modified polysulfones, together with ceramic-organic hybrids, offer superior oxidation resistance, withstanding exposure to 10 ppm chlorine, and maintain pH stability across a wide range of 1 to 12 pH.
Advanced Anti-Fouling Surface Engineering
Our superhydrophilic surface, with a contact angle of less than 10°, reinforced with nanoparticles, significantly reduces the tendency for organic fouling by 50%. This extends the interval for chemical cleaning from 3 months to an impressive 6 months, leading to a 40% reduction in maintenance costs.
