Our Advantages

Proshare Pioneering Breakthroughs in Advanced Reverse Osmosis Membrane Technology
Proshare The Proshare team has ingeniously engineered a groundbreaking new generation of reverse osmosis membranes leveraging pioneering polymer interface nano-self-assembly technology. This revolutionary approach overcomes traditional limitations with two standout advancements:
Revolutionary Ultra-Thin Separation Layer: Utilizing cutting-edge polymer interface nanotechnology, our team has reduced the separation layer's thickness to an astonishing threefold thinner than conventional polyamide thin films (historically capped at 100 nm). This milestone dramatically boosts water flux, leading to a remarkable increase in permeability.
Unparalleled Performance Enhancement: The strategic incorporation of nanoparticles and specialized hydrophilic polymers has unlocked unprecedented enhancements in the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance.
When compared to conventional polyamide reverse osmosis membranes, Proshare's innovation manifests breakthroughs across four pivotal dimensions:
Self-Assembled Nanocomposite Films
By integrating nano-scale precision control and nano-doping modification, we achieve ultra-thin, highly ordered separation layers through polymer interface nanotechnology. This novel approach transcends the constraints of conventional polyamide membranes in both thickness uniformity and material diversity.
Elevated Water Flux and Energy Efficiency
Through the meticulous optimization of the layer-by-layer self-assembly process, the functional layer thickness is finely tuned, achieving a staggering 3x reduction in comparison to traditional membranes. This advancement results in a water flux over three times greater and a 30% reduction in energy consumption.
Innovative Polymer Materials with Outstanding Chemical Stability
Venturing beyond polyamide, our team employs cutting-edge hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These materials showcase exceptional oxidation resistance (capable of withstanding exposure to 10 ppm chlorine) and superior pH tolerance (remaining stable across a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
The superhydrophilic surface (with a contact angle under 10°), bolstered by nanoparticle reinforcement, reduces the propensity for organic fouling by 50%, thereby extending chemical cleaning cycles from 3 to 6 months and slashing maintenance costs by 40%.
