Proshare Team's Breakthrough in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare team has trailblazed a revolutionary new generation of reverse osmosis membranes utilizing polymer interface nano-self-assembly technology, overcoming the constraints of traditional reverse osmosis membrane development through two groundbreaking advancements:
Ultra-Thin Separation Layer: By leveraging cutting-edge polymer interface nanotechnology, the team has achieved a remarkable reduction in the thickness of the separation layer to at least three times thinner than conventional polyamide thin films (previously capped at 100 nm). This milestone significantly boosts water flux, heralding a substantial enhancement in permeability.
Enhanced Performance: The incorporation of nanoparticles and bespoke hydrophilic polymers has driven monumental advancements in the membrane's hydrophilicity, anti-fouling capability, longevity, and oxidation resistance.
When compared with 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 and nano-doping modification empowers the creation of ultra-thin, impeccably ordered separation layers through polymer interface nanotechnology. This sophisticated approach transcends the limitations of conventional polyamide membranes in thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By meticulously optimizing the layer-by-layer self-assembly process, the functional layer thickness is precisely managed, achieving a 3-fold reduction compared to conventional membranes. The result is >3x amplified water flux and 30% reduced energy consumption.
Innovative Polymer Materials with Exceptional Chemical Stability
Moving beyond the confines of polyamide, the team employs cutting-edge hydrophilic polymers such as modified polysulfones and ceramic-organic hybrids. These materials exhibit outstanding oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH resilience (ensuring stability across a pH range of 1-12).
Anti-Fouling Surface Engineering
The ultra-hydrophilic surface (contact angle <10°) coupled with nanoparticle reinforcement slashes organic fouling potential by 50%, doubling chemical cleaning cycles from 3 months to 6 months, and reducing maintenance expenses by 40%.
