Our Advantages

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our visionary team has brilliantly engineered a new generation of reverse osmosis membranes utilizing cutting-edge polymer interface nano-self-assembly technology. This innovation triumphs over the traditional constraints of reverse osmosis membrane development through two revolutionary advancements:
Ultra-Thin Separation Layer: By harnessing the power of polymer interface nanotechnology, our team has remarkably reduced the separation layer's thickness to an unprecedented threefold finer than traditional polyamide thin films (which were previously capped at 100 nm). This monumental breakthrough dramatically enhances water flux, marking a substantial leap in permeability.
Enhanced Performance: The strategic incorporation of nanoparticles and specially designed hydrophilic polymers has resulted in groundbreaking improvements in the membrane's hydrophilicity, anti-fouling capabilities, durability, and resistance to oxidation.
Compared to conventional polyamide reverse osmosis membranes, Proshare's cutting-edge innovation showcases breakthroughs across four pivotal dimensions:
Self-Assembled Nanocomposite Films
The fusion of nano-scale precision control and nano-doping modification allows for the creation of ultra-thin, highly ordered separation layers through polymer interface nanotechnology. This pioneering approach surmounts the conventional polyamide membranes' constraints in thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, we achieve precise control over the functional layer thickness, resulting in an impressive threefold reduction compared to traditional membranes. This innovation leads to >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Venturing beyond polyamide, we employ advanced hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids, which offer exceptional oxidation resistance (capable of withstanding 10 ppm chlorine exposure) and pH tolerance (stability maintained across a pH range of 1-12).
Anti-Fouling Surface Engineering
Our superhydrophilic surface (with contact angles less than 10°), reinforced with nanoparticles, cuts organic fouling tendency by 50%, extends chemical cleaning cycles from 3 to 6 months, and reduces maintenance costs by 40%.
