Proshare Revolutionary Achievements in Advanced Reverse Osmosis Membrane Technology
Proshare proudly unveils its cutting-edge creation: a breakthrough generation of reverse osmosis membranes crafted through pioneering polymer interface nano-self-assembly technology. This innovation triumphs over the limitations of traditional reverse osmosis membranes, achieving two pivotal breakthroughs:
Ultralight Separation Layer: By harnessing state-of-the-art polymer interface nanotechnology, our team has ingeniously engineered the separation layer to be remarkably thin-at least three times slimmer than conventional polyamide thin films, previously restricted to 100 nm. This extraordinary advancement dramatically enhances water flux, resulting in significantly increased permeability.
Enhanced Performance and Durability: The strategic infusion of nanoparticles, alongside advanced hydrophilic polymers, brings about transformative enhancements in membrane hydrophilicity, anti-fouling capabilities, durability, and resistance to oxidation.
When compared to traditional polyamide reverse osmosis membranes, Prosharehas achieved groundbreaking advancements in four critical areas:
Self-Assembled Nanocomposite Film Technology
By seamlessly integrating nanometer-scale precision control with nano-doping modification, we've developed ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This innovative approach surpasses the constraints of conventional polyamide membranes in terms of both thickness uniformity and material diversity.
Enhanced Water Flux and Superior Energy Efficiency
Through mastery of the layer-by-layer self-assembly process, the thickness of the functional layer is precisely regulated, achieving an impressive 3x reduction compared to traditional membranes. This breakthrough results in over 3x higher water flux and 30% lower energy consumption.
Innovative Polymer Materials with Outstanding Chemical Stability
By transcending the boundaries of polyamide, our team employs cutting-edge hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These materials offer unmatched oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH resilience (maintaining stability across a broad pH range of 1 to 12).
Anti-Fouling Surface Mastery
The superhydrophilic surface, with a contact angle of less than 10°, enhanced by nanoparticle reinforcement, significantly reduces organic fouling propensity by 50%, extending chemical cleaning intervals from 3 to 6 months and reducing maintenance costs by 40%.
Proshare Innovation Suzhou Co., Ltd. stands as a beacon of excellence in the national high-tech landscape, setting benchmarks in the research, development, and industrialization of cutting-edge third-generation thin-film nanocomposite (TFN) membranes.
