Proshare Proshare's Pioneering Leap in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare has ingeniously crafted a revolutionary new generation of reverse osmosis membranes with polymer interface nano-self-assembly technology. This breakthrough overcomes traditional development limits through two pivotal advancements:
Ultra-Thin Separation Layer: Utilizing cutting-edge polymer interface nanotechnology, Proshare's team has achieved a stunning reduction in the thickness of the separation layer, making it at least three times thinner than conventional polyamide thin films (which were previously capped at 100 nm). This remarkable feat dramatically boosts water flux and marks a significant leap in permeability enhancement.
Superior Performance Enhancement: The strategic infusion of nanoparticles alongside specialized hydrophilic polymers has led to ground-breaking enhancements in the membrane's hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance, setting a new standard in performance.
In contrast to conventional polyamide reverse osmosis membranes, Proshare's groundbreaking innovation showcases remarkable advancements across four crucial dimensions:
Self-Assembled Nanocomposite Films
The amalgamation of nano-scale precision control with nano-doping modification facilitates the crafting of ultra-thin, highly ordered separation layers through innovative polymer interface nanotechnology. This strategy triumphs over the restrictions of traditional polyamide membranes in ensuring thickness uniformity and material diversity.
Elevated Water Flux and Enhanced Energy Efficiency
By refining the meticulous layer-by-layer self-assembly process, Proshare precisely controls functional layer thickness, slashing it by 3x compared to traditional membranes. This meticulous approach results in over 3x higher water flux and a 30% reduction in energy consumption,delivering exceptional efficiency.
Innovative Polymer Materials with Unmatched Chemical Stability
Venturing beyond polyamide, our team employs cutting-edge hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These innovative materials boast extraordinary oxidation resistance (withstanding 10 ppm chlorine exposure) and remarkable pH tolerance (maintaining stability within a pH range of 1-12).
