Proshare Team's Revolutionary Leap in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare team has pioneered an innovative development of a new era in reverse osmosis membranes, harnessing the power of polymer interface nano-self-assembly technology. This cutting-edge approach has shattered the constraints of traditional reverse osmosis membrane development by achieving two pivotal advancements:
Ultra-Thin Separation Layer: Utilizing the ingenious application of polymer interface nanotechnology, our team has remarkably minimized the thickness of the separation layer to a third of the conventional polyamide thin film, previously limited to 100 nm. This extraordinary advancement notably boosts water flux, ensuring a remarkable enhancement in permeability.
Augmented Performance: The strategic incorporation of nanoparticles and specialized hydrophilic polymers has propelled groundbreaking strides in the membrane's hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance, setting new industry standards.
In comparison with traditional polyamide reverse osmosis membranes, Proshare's innovation showcases groundbreaking achievements across four significant dimensions:
Self-Assembled Nanocomposite Films
The fusion of nano-scale precision control and nano-doping modification empowers the formation of ultra-thin, highly ordered separation layers via polymer interface nanotechnology. This method successfully transcends the limits of conventional polyamide membranes in terms of thickness uniformity and material diversity.
Elevated Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, the functional layer thickness has been finely tuned, achieving a threefold reduction compared to traditional membranes. This leads to a water flux exceeding three times the norm with a 30% reduction in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Breaking free from polyamide, the team leverages advanced hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids, showcasing exceptional oxidation resistance (withstanding up to 10 ppm chlorine exposure) and pH resilience (maintaining stability in a pH range from 1 to 12).
