Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare team has innovatively developed a new generation of reverse osmosis membranes based on polymer interface nano-self-assembly technology, overcoming the limitations of traditional reverse osmosis membrane development through two key advancements:
Ultra-Thin Separation Layer: By employing cutting-edge polymer interface nanotechnology, the team has achieved a remarkable feat by crafting a separation layer which is at least three times thinner than the conventional polyamide thin film. Previously constrained to 100 nm, this technological leap forward significantly boosts water flux, resulting in a remarkable improvement in permeability.
Enhanced Performance: Through the introduction of nanoparticles and unique hydrophilic polymers, the team has unlocked groundbreaking advancements in the membrane's hydrophilicity, anti-fouling properties, durability, and resistance to oxidation.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases breakthroughs in four pivotal aspects:
Self-Assembled Nanocomposite Films
The fusion of nano-scale precision control with nano-doping modification paves the way for creating ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This innovation overcomes the shortcomings of conventional polyamide membranes in terms of thickness uniformity and material variation.
Enhanced Water Flux and Energy Efficiency
By meticulously optimizing the layer-by-layer self-assembly process, the functional layer thickness is precisely regulated, achieving a remarkable threefold reduction compared to traditional membranes. This leads to >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Surpassing polyamide, the team employs advanced hydrophilic polymers, such as modified polysulfones and ceramic-organic hybrids. These materials demonstrate exceptional oxidation resistance (withstanding 10 ppm chlorine exposure) and pH tolerance (remaining stable across a 1-12 pH range).
Anti-Fouling Surface Engineering
The superhydrophilic surface, with a contact angle of less than 10°, combined with nanoparticle reinforcement, reduces the propensity for organic fouling by 50%. This extends the interval for chemical cleaning cycles from 3 months to 6 months and slashes maintenance costs by 40%.
