ProshareTeam's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
ProshareOur team has pioneered a groundbreaking advancement in reverse osmosis membrane technology. By harnessing the cutting-edge capabilities of polymer interface nano-self-assembly, we have redefined the landscape of membrane development with two revolutionary innovations:
Ultra-Thin Separation Layer: Through the pioneering use of polymer interface nanotechnology, we have crafted a separation layer that is at least three times thinner than traditional 100 nm polyamide thin films. This revolutionary reduction in thickness significantly boosts water flux, dramatically enhancing permeability and overall efficiency.
Enhanced Performance: By integrating nanoparticles with specialized hydrophilic polymers, we have achieved unparalleled advancements in the membrane's hydrophilicity, anti-fouling properties, durability, and resistance to oxidation, setting a new standard in performance.
Compared to traditional polyamide reverse osmosis membranes,Proshare's innovation shines through breakthroughs in four pivotal areas:
Self-Assembled Nanocomposite Films
Combining nano-scale precision control with nano-doping modification allows the creation of ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This groundbreaking approach surpasses traditional limitations of thickness uniformity and material diversity in polyamide membranes.
Enhanced Water Flux and Energy Efficiency
By perfecting the layer-by-layer self-assembly process, we have finely tuned the functional layer thickness, achieving an extraordinary reduction to one-third of traditional membranes, resulting in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Moving away from polyamide, our team utilizes advanced hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These materials offer superior oxidation resistance (withstanding 10 ppm chlorine exposure) and pH tolerance (remaining stable in a 1-12 pH range).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, designed with a contact angle below 10° and enhanced by nanoparticle reinforcement, effectively cuts organic fouling by 50%. This innovation extends chemical cleaning cycles from 3 to 6 months, slashing maintenance costs by 40%.
