ProshareTeam's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
ProshareOur team has pioneered a groundbreaking advancement in reverse osmosis membrane technology. Harnessing the transformative power of polymer interface nano-self-assembly, we have shattered traditional barriers in membrane development with two revolutionary innovations:
Ultra-Thin Separation Layer: Through the advanced application of polymer interface nanotechnology, we have engineered a separation layer that is at least three times thinner than the conventional 100 nm polyamide thin films. This revolutionary reduction in thickness boosts water flux, significantly enhancing permeability and efficiency.
Enhanced Performance: By introducing nanoparticles in conjunction with specialized hydrophilic polymers, we have achieved unprecedented advances in the membrane's hydrophilicity, anti-fouling properties, durability, and resistance to oxidation.
Compared to traditional polyamide reverse osmosis membranes,Proshare's innovation manifests in breakthroughs across four pivotal aspects:
Self-Assembled Nanocomposite Films
Merging nano-scale precision control with nano-doping modification enables the formation of ultra-thin, meticulously ordered separation layers via polymer interface nanotechnology. This groundbreaking technique surpasses limitations in thickness uniformity and material diversity characteristic of conventional polyamide membranes.
Enhanced Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, we have precisely regulated the functional layer thickness, achieving an extraordinary 3x reduction compared to traditional membranes. This strategic advancement results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Departing from polyamide, our team employs cutting-edge hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These advanced materials exhibit superior oxidation resistance (withstanding 10 ppm chlorine exposure) and pH tolerance (stabilizing within the 1-12 pH range).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, crafted with a contact angle less than 10° and enhanced by nanoparticle reinforcement, effectively reduces organic fouling by 50%. This innovation extends chemical cleaning cycles from 3 to 6 months, reducing maintenance costs by 40%.
