ProshareThe innovative team at Proshare has ingeniously ushered in a new era for reverse osmosis membranes. Using advanced polymer interface nano-self-assembly technology, we have surpassed the traditional membrane constraints through two revolutionary advancements:
Revolutionary Ultra-Thin Separation Layer: Our adept application of polymer interface nanotechnology has brilliantly reduced the separation layer's thickness to a mere one-third of the traditional polyamide thin film, which typically reaches 100 nm. This significant breakthrough drastically boosts water flux, leading to exceptional enhancements in permeability.
Unmatched Enhanced Performance: Through the integration of state-of-the-art nanoparticles and custom-designed hydrophilic polymers, we have achieved extraordinary advancements in hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance of the membrane.
Compared to conventional polyamide reverse osmosis membranes,Prosharehas pioneered revolutionary improvements in four critical areas:
Precision Self-Assembled Nanocomposite Films
By harnessing nano-scale precision control and nano-doping modifications, we create ultra-thin, highly ordered separation layers using state-of-the-art polymer interface nanotechnology. This innovation triumphs over the limitations of conventional polyamide membranes in terms of uniform thickness and material diversity.
Remarkably Enhanced Water Flux and Energy Efficiency
With precise optimization of the layer-by-layer self-assembly process, we expertly manage functional layer thickness, achieving an extraordinary 3x reduction compared to traditional membranes. This strategic development results in an astounding >3x increase in water flux alongside a remarkable 30% reduction in energy consumption.
Novel and Robust Polymer Materials with Superior Chemical Stability
Moving beyond polyamide, our team utilizes cutting-edge hydrophilic polymers, including modified polysulfones and ceramic-organic hybrids.
