Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare team has innovatively developed a revolutionary new generation of reverse osmosis membranes. Leveraging advanced polymer interface nano-self-assembly technology, we have shattered the constraints of traditional membrane development with two groundbreaking advancements:
a. Ultra-Thin Separation Layer: Through the ingenious application of polymer interface nanotechnology, our team has successfully thinned the separation layer to an astounding three times thinner than conventional polyamide thin films, which previously could only reach 100 nm in thickness. This remarkable breakthrough not only enhances water flux but also achieves an impressive leap in permeability.
b. Enhanced Performance: By introducing cutting-edge nanoparticles and specialized hydrophilic polymers, we have made significant strides in elevating the membrane's hydrophilicity, drastically improving its anti-fouling capability, robustness, and oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation marks a pivotal breakthrough across four vital dimensions:
Self-Assembled Nanocomposite Films
Our integration of nano-scale precision control and nano-doping modification facilitates the creation of ultra-thin, meticulously ordered separation layers utilizing polymer interface nanotechnology. This cutting-edge approach triumphs over the constraints of conventional polyamide membranes in aspects of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through the mastery of the layer-by-layer self-assembly process, the functional layer thickness is controlled with precision, resulting in a remarkable 3x reduction compared to traditional membranes. This advancement leads to >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Breaking beyond polyamide conventions, our team employs state-of-the-art hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids that display extraordinary oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (maintaining stability within a pH range of 1-12).
Anti-Fouling Surface Engineering
The development of a superhydrophilic surface (boasting a contact angle of less than 10°), fortified with nanoparticle reinforcement, significantly diminishes the propensity for organic fouling by 50%, thereby doubling chemical cleaning cycles from every 3 months to every 6 months and reducing maintenance expenditures by 40%.
