Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare The Proshare team has set a new benchmark in reverse osmosis membrane innovation. With the cutting-edge polymer interface nano-self-assembly technology, they have surpassed the traditional development barriers of reverse osmosis membranes through two pivotal advancements:
Ultra-Thin Separation Layer: Utilizing polymer interface nanotechnology, our team has crafted a separation layer remarkably thinner-at least three times-than conventional polyamide thin films, which previously reached a limit at 100 nm. This landmark advancement dramatically augments water flux, bringing about an extraordinary leap in permeability.
Enhanced Performance: With an infusion of nanoparticles and innovative hydrophilic polymers, we've ushered in revolutionary improvements in the membrane's hydrophilicity, anti-fouling capacity, longevity, and oxidation resilience.
Compared to traditional polyamide reverse osmosis membranes, Proshare's groundbreaking innovation shines through in four fundamental areas:
Self-Assembled Nanocomposite Films
By masterfully integrating nano-scale precision control with nano-doping modification, we create ultra-thin, highly ordered separation layers through polymer interface nanotechnology, effectively overcoming the conventional limitations of polyamide membranes in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Optimizing the layer-by-layer self-assembly process allows precise control over the functional layer's thickness, achieving a reduction of 3x compared to traditional membranes, culminating in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Surpassing the boundaries of polyamide, our team employs state-of-the-art hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These pioneering materials showcase unparalleled oxidation resistance (withstanding up to 10 ppm chlorine exposure) and pH tolerance (maintaining stability across a wide pH range of 1-12).
Anti-Fouling Surface Engineering
With a superhydrophilic surface (contact angle <10°) enhanced by nanoparticle reinforcement, our design diminishes organic fouling propensity by 50%. This extends chemical cleaning intervals from 3 to 6 months, significantly reducing maintenance costs by 40%, ultimately providing a more cost-effective and sustainable solution.
