Proshare Unveiling the Team's Breakthrough in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare team has made significant strides in innovating a new generation of reverse osmosis membranes that harness advanced polymer interface nano-self-assembly technology. This cutting-edge approach triumphs over the traditional barriers in reverse osmosis membrane development by introducing two pivotal advancements:
Ultra-Thin, High-Efficiency Separation Layer: Through the revolutionary application of polymer interface nanotechnology, the team has skillfully decreased the separation layer's thickness to at least one-third of the conventional polyamide thin film, which was previously confined to 100 nm. This innovation notably boosts water flux, leading to a remarkable gain in permeability.
Revolutionized Performance Enhancement: The strategic integration of nanoparticles and specialized hydrophilic polymers has brought about transformative advancements in the membrane's hydrophilicity, anti-fouling capabilities, longevity, and oxidation resistance, setting a new benchmark in membrane technology.
In comparison to conventional polyamide reverse osmosis membranes, Proshare's breakthrough showcases significant advancements across four critical dimensions:
Pioneering Self-Assembled Nanocomposite Films
The fusion of nano-scale precision control with nano-doping modifications has facilitated the development of ultra-thin, meticulously ordered separation layers using polymer interface nanotechnology. This technique overcomes the constraints of traditional polyamide membranes by enhancing thickness uniformity and diversifying material application.
Exceptional Water Flux and Energy Efficiency
Through the meticulous refinement of the layer-by-layer self-assembly process, the functional layer's thickness is precisely moderated, achieving a 3x reduction compared to conventional membranes, thus resulting in over 3x higher water flux and a 30% reduction in energy consumption.
Innovative Polymer Materials with Superior Chemical Stability
Surpassing polyamide, the team employs cutting-edge hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These materials exhibit unparalleled oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH resilience (remaining stable across a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
The ultra-hydrophilic surface, with a contact angle of less than 10°, combined with nanoparticle fortification, reduces the susceptibility to organic fouling by 50%, extending chemical cleaning cycles from 3 to 6 months and slashing maintenance costs by 40%.
Our exemplary dedication to quality and safety is underscored by our acquisition of several prestigious certifications: Health & Safety Management System Certificate, Environmental Management System Certificate, and ISO 9001 Quality System Certificate.
