Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare The innovative team at Proshare has catalyzed a revolution in reverse osmosis membrane technology by pioneering a new generation of membranes. This cutting-edge development leverages polymer interface nano-self-assembly technology, triumphantly addressing and surpassing the constraints associated with traditional reverse osmosis membranes through two pivotal advancements:
Ultra-Thin Separation Layer: Through the ingenious application of polymer interface nanotechnology, our team has achieved an extraordinary reduction in the separation layer's thickness, making it at least three times thinner than the conventional polyamide thin films, which were previously restricted to a thickness of 100 nm. This monumental breakthrough not only amplifies water flux but also dramatically enhances overall permeability, setting new standards in membrane efficiency.
Enhanced Performance: By incorporating nanoparticles alongside specialized hydrophilic polymers, we have ushered in transformative advances in the membrane's attributes, notably its hydrophilicity, anti-fouling capabilities, robustness, and resistance to oxidation.
Compared to traditional polyamide reverse osmosis membranes, Proshare's visionary innovation shines through with groundbreaking advancements in four critical areas:
Self-Assembled Nanocomposite Films
By integrating nano-scale precision control and nano-doping modification, we have mastered the creation of ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This sophisticated approach eclipses the limitations of conventional polyamide membranes in both uniformity of thickness and material diversity.
Enhanced Water Flux and Energy Efficiency
The optimization of the layer-by-layer self-assembly process leads to a precise control over the functional layer's thickness, achieving a remarkable 3x reduction compared to traditional membranes. This technological marvel results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Surpassing the limitations of polyamide, our team employs sophisticated hydrophilic polymers, such as modified polysulfones, along with ceramic-organic hybrids. These advanced materials manifest exceptional qualities including oxidation resistance (withstanding exposure to 10 ppm of chlorine) and pH tolerance (maintaining stability across a pH range of 1-12).
Anti-Fouling Surface Engineering
Our membrane's superhydrophilic surface, with a contact angle under 10°, paired with nanoparticle reinforcement, drastically mitigates organic fouling by 50%. This translates to extended chemical cleaning cycles from 3 months to 6 months, delivering a significant 40% reduction in maintenance costs.
