Proshare Pioneering Breakthrough in Next-Generation Reverse Osmosis Technology
Proshare The Proshare team has achieved a remarkable feat by innovatively crafting a new generation of reverse osmosis membranes. Utilizing cutting-edge polymer interface nano-self-assembly technology, the team has surmounted the traditional development limitations of reverse osmosis membranes with two pivotal advancements:
Ultra-Thin Separation Layer: By leveraging the power of polymer interface nanotechnology, our team has successfully reduced the separation layer to an astounding thickness, at least three times thinner than the conventional 100 nm polyamide thin film. This technological leap significantly boosts water flux, delivering a substantial improvement in permeability.
Enhanced Performance: The innovative incorporation of nanoparticles and specialized hydrophilic polymers ushers in groundbreaking enhancements in hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance of the membrane.
In comparison to traditional polyamide reverse osmosis membranes, Proshare's innovation marks breakthroughs in four core dimensions:
Self-Assembled Nanocomposite Films
By integrating nano-level precision control with nano-doping modification, we create ultra-thin, highly ordered separation layers through polymer interface nanotechnology. This method triumphs over the usual constraints of conventional polyamide membranes regarding thickness uniformity and material versatility.
Enhanced Water Flux and Energy Efficiency
By optimizing the intricate layer-by-layer self-assembly process, we precisely control the thickness of the functional layer, achieving a remarkable 3x reduction relative to traditional membranes. Consequently, this results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Venturing beyond polyamide, our team employs advanced hydrophilic polymers, such as modified polysulfones, alongside ceramic-organic hybrids. These cutting-edge materials demonstrate extraordinary oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (remaining stable across a pH range of 1-12).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, featuring a contact angle of less than 10°, combined with nanoparticle reinforcement, dramatically reduces organic fouling propensity by 50%. This extends chemical cleaning intervals from 3 months to an impressive 6 months, while slashing maintenance costs by 40%
