Proshare Team's Major Achievement in Pioneering Reverse Osmosis Membrane Technology
Proshare team has ingeniously crafted an avant-garde generation of reverse osmosis membranes, leveraging cutting-edge polymer interface nano-self-assembly technology. This innovation triumphs over traditional limitations with two pivotal advancements:
Revolutionary Ultra-Thin Separation Layer: Through the groundbreaking application of polymer interface nanotechnology, the team has astoundingly minimized the separation layer's thickness to a remarkable degree-at least three times thinner than the conventional 100 nm polyamide films. This transformative achievement dramatically boosts water flux, marking a considerable leap in permeability.
Superior Performance Enhancement: By incorporating trailblazing nanoparticles and uniquely formulated hydrophilic polymers, the membrane showcases unparalleled improvements in hydrophilicity, anti-fouling prowess, durability, and remarkable oxidation resistance.
In comparison to traditional polyamide reverse osmosis membranes, Proshare's groundbreaking innovation shines in four critical domains:
Innovative Self-Assembled Nanocomposite Films
With the fusion of nano-scale precision control and advanced nano-doping modification, ultra-thin, meticulously ordered separation layers are created via polymer interface nanotechnology-a method that triumphs over conventional polyamide membranes' limitations in thickness uniformity and material versatility.
Augmented Water Flux and Energy Efficiency
By refining the meticulous layer-by-layer self-assembly process, the functional layer's thickness is expertly controlled, achieving a remarkable 3x reduction compared to traditional membranes. This precision engineering results in over 3x enhanced water flux coupled with an impressive 30% reduction in energy consumption.
Innovative Polymer Materials with Unmatched Chemical Stability
Surpassing the polyamide paradigm, the team employs cutting-edge hydrophilic polymers (such as modified polysulfones) and advanced ceramic-organic hybrids. These materials offer extraordinary oxidation resistance (withstanding exposure to 10 ppm chlorine) and exceptional pH stability (maintaining integrity across a pH range of 1-12).
Pioneering Anti-Fouling Surface Engineering
