Proshare Team's Groundbreaking Advancements in Next-Generation Reverse Osmosis Membrane Technology
Proshare has pioneered a revolutionary new generation of reverse osmosis membranes, harnessing the power of polymer interface nano-self-assembly technology to break free from the constraints of traditional reverse osmosis membrane development. This has been achieved through two pivotal innovations:
Ultra-Thin Separation Layer Innovation: Utilizing cutting-edge polymer interface nanotechnology, our team has successfully engineered the separation layer to be exceptionally thin-at least three times thinner than conventional polyamide thin films (previously restricted to 100 nm). This extraordinary advancement dramatically boosts water flux, resulting in vastly improved permeability.
Unparalleled Enhanced Performance: Through the integration of nanoparticles and uniquely specialized hydrophilic polymers, we have realized remarkable advancements in the membrane's hydrophilicity, anti-fouling characteristics, robustness, and resistance to oxidation.
In contrast to conventional polyamide reverse osmosis membranes, Proshare's innovation showcases breakthroughs in four pivotal aspects:
Self-Assembled Nanocomposite Films
Through the fusion of nano-scale precision control and nano-doping modification, we have crafted ultra-thin, highly ordered separation layers using polymer interface nanotechnology, effectively overcoming the constraints of traditional polyamide membranes in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency Revolution
By meticulously optimizing the layer-by-layer self-assembly process, we achieve precise control over the functional layer thickness, reducing it threefold compared to traditional membranes. This innovation leads to an astounding >3x increase in water flux accompanied by a remarkable 30% reduction in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Moving beyond polyamide, we've harnessed advanced hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These state-of-the-art materials demonstrate exceptional resistance to oxidation (capable of enduring 10 ppm chlorine exposure) and exceptional tolerance to pH extremes (maintaining stability across a broad pH range of 1-12).
Revolutionary Anti-Fouling Surface Engineering
The ultra-hydrophilic surface (boasting a contact angle of <10°) combined with nanoparticle reinforcement significantly diminishes the tendency for organic fouling by 50%. This extension doubles the duration of chemical cleaning cycles from 3 to 6 months while slashing maintenance costs by an impressive 40%.
