Proshare Pioneering Breakthroughs in Advanced Reverse Osmosis Membrane Technology
Proshare Our team at Proshare has masterfully forged ahead with the creation of a next-generation reverse osmosis membrane. Utilizing cutting-edge polymer interface nano-self-assembly technology, we have surpassed the traditional barriers of membrane development through two remarkable advancements:
Ultra-Thin Separation Layer Excellence: By harnessing state-of-the-art polymer interface nanotechnology, the team achieved a groundbreaking reduction in the separation layer's thickness, making it at least three times thinner than the conventional polyamide thin film, which was previously capped at 100 nm. This revolutionary progress significantly boosts water flux and dramatically improves permeability.
Enhanced Performance and Durability: The strategic incorporation of nanoparticles and advanced hydrophilic polymers has resulted in extraordinary improvements in membrane hydrophilicity, superior anti-fouling properties, enhanced durability, and exceptional oxidation resistance.
In contrast with traditional polyamide reverse osmosis membranes, Proshare's innovation showcases significant breakthroughs in four essential areas:
Self-Assembled Nanocomposite Films
By integrating nano-scale precision control and nano-doping modifications, we have crafted ultra-thin, meticulously ordered separation layers through the use of polymer interface nanotechnology. This approach effectively surpasses the constraints of conventional polyamide membranes in terms of thickness uniformity and material diversity.
Superior Water Flux and Energy Efficiency
Through the optimization of the layer-by-layer self-assembly process, we precisely control the functional layer thickness, achieving an impressive 3x reduction compared to traditional membranes. This innovation results in a water flux that exceeds traditional capabilities by over three times and ensures a 30% reduction in energy consumption.
Innovative Polymer Materials with Outstanding Chemical Stability
Venturing beyond polyamide, our team employs cutting-edge hydrophilic polymers, like modified polysulfones, alongside ceramic-organic hybrids. These advanced materials boast remarkable oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and exhibit incredible pH resilience (maintaining stability across a wide pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
Our superhydrophilic surface, characterized by a contact angle less than 10°, combined with nanoparticle enhancements, dramatically reduces organic fouling by 50%. This advancement extends chemical cleaning intervals from 3 months to an impressive 6 months, slashing maintenance expenses by 40%.
