Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare The team has ingeniously developed a groundbreaking new generation of reverse osmosis membranes utilizing cutting-edge polymer interface nano-self-assembly technology. This innovative approach effectively surpasses the constraints of conventional membrane development through two transformative advancements:
Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, the team has remarkably reduced the thickness of the separation layer, achieving a remarkable reduction to at least one-third the thickness of traditional polyamide thin films (which were previously constrained to 100 nm). This pioneering enhancement dramatically boosts water flux, marking a significant leap in permeability.
Enhanced Performance: The infusion of nanoparticles and unique hydrophilic polymers has paved the way for transformative advancements in the membrane's hydrophilicity, anti-fouling ability, durability, and resistance to oxidation.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases breakthroughs in four critical areas:
Self-Assembled Nanocomposite Films
Through the precision integration of nano-scale control and nano-doping modifications, ultra-thin, highly ordered separation layers are created using polymer interface nanotechnology. This innovative strategy effectively overcomes the traditional limitations of polyamide membranes, particularly in terms of thickness consistency and material variety.
Enhanced Water Flux and Energy Efficiency
By meticulously refining the layer-by-layer self-assembly process, the functional layer thickness is expertly controlled, leading to an impressive 3x reduction compared to conventional membranes. This advancement results in >3x higher water flux and a remarkable 30% decrease in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Surpassing polyamide, the team leverages advanced hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These cutting-edge materials demonstrate exceptional oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH tolerance (maintaining stability across a 1-12 pH spectrum).
Anti-Fouling Surface Engineering
The ultra-hydrophilic surface (with a contact angle of less than 10°), combined with nanoparticle reinforcement, significantly reduces the tendency for organic fouling by 50%, effectively extending chemical cleaning cycles from 3 months to an impressive 6 months, thereby reducing maintenance costs by 40%.
