Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our pioneering team has ingeniously crafted a new era of reverse osmosis membranes, leveraging polymer interface nano-self-assembly technology. This cutting-edge innovation triumphantly surpasses the conventional limitations of traditional reverse osmosis membrane development through two remarkable advancements:
Ultra-Thin Separation Layer: Utilizing the power of polymer interface nanotechnology, our team has strategically minimized the separation layer's thickness to a fraction, making it at least three times thinner than the traditional polyamide thin film, which was previously limited to 100 nm. This revolutionary breakthrough dramatically enhances water flux, realizing an outstanding improvement in permeability.
Enhanced Performance: With the strategic introduction of nanoparticles and advanced hydrophilic polymers, extraordinary advancements have been achieved in membrane hydrophilicity, anti-fouling capability, durability, and oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's exceptional innovation marks significant breakthroughs in four pivotal areas:
Self-Assembled Nanocomposite Films
The fusion of nano-scale precision control with nano-doping modification empowers the creation of ultra-thin, highly ordered separation layers through polymer interface nanotechnology. This innovative approach triumphs over the conventional challenges of polyamide membranes, particularly in thickness uniformity and material diversification.
Enhanced Water Flux and Energy Efficiency
By refining the layer-by-layer self-assembly process, the functional layer thickness is meticulously controlled, achieving a remarkable 3x reduction compared to traditional membranes. This precision engineering results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Transcending polyamide, the team employs cutting-edge hydrophilic polymers, such as modified polysulfones and ceramic-organic hybrids, which exhibit unparalleled oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (remaining stable across a 1-12 pH range).
Anti-Fouling Surface Engineering
