Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare The pioneering team at Proshare has masterfully developed a groundbreaking new generation of reverse osmosis membranes. Utilizing cutting-edge polymer interface nano-self-assembly technology, they have transcended the boundaries of conventional reverse osmosis membrane development through two transformative advancements:
Ultra-Thin Separation Layer: Through the revolutionary application of polymer interface nanotechnology, the team has remarkably reduced the separation layer's thickness to an impressive one-third of traditional polyamide thin films (historically constrained at 100 nm). This monumental leap forward substantially enhances water flux, delivering a profound improvement in permeability.
Enhanced Performance: The strategic incorporation of nanoparticles and advanced hydrophilic polymers has propelled pioneering advancements in the membrane's hydrophilicity, anti-fouling proficiency, durability, and oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation unveils remarkable breakthroughs in four pivotal domains:
Self-Assembled Nanocomposite Films
The synthesis of nano-scale precision control with nano-doping modification facilitates the creation of ultra-thin, highly ordered separation layers through polymer interface nanotechnology. This innovative method triumphs over the conventional polyamide membranes' limitations in thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By refining the layer-by-layer self-assembly process, the functional layer's thickness is meticulously regulated, achieving a stunning 3x reduction compared to traditional membranes. This optimization leads to >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Surpassing polyamide, the team employs leading-edge hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These avant-garde materials demonstrate extraordinary oxidation resistance (withstanding up to 10 ppm chlorine exposure) and pH tolerance (maintaining stability within a 1-12 pH range).
Anti-Fouling Surface Engineering
The ultra-hydrophilic surface (contact angle <10°) combined with nanoparticle enhancement dramatically reduces the tendency for organic fouling by 50%, extending chemical cleaning cycles from 3 months to a remarkable 6 months, while reducing maintenance costs by an impressive 40%.
