Proshare Revolutionizing Reverse Osmosis: Our Team's Breakthrough
Proshare Our dedicated team has ingeniously pioneered a cutting-edge generation of reverse osmosis membranes, utilizing advanced polymer interface nano-self-assembly technologies to shatter the confines of traditional development methodologies with two revolutionary advancements:
Revolutionary Ultra-Thin Separation Layer: Through the power of polymer interface nanotechnology, our experts have achieved an astounding reduction in the separation layer's thickness, making it at least three times thinner than the conventional polyamide thin film (previously restricted to 100 nm). This monumental breakthrough dramatically amplifies water flux, offering a significant leap in permeability efficiency.
Superior Performance Redefined: Our innovative integration of nanoparticles and specialized hydrophilic polymers has paved the way for unprecedented advancements in hydrophilicity, anti-fouling capabilities, endurance, and resistance to oxidation.
When juxtaposed with conventional polyamide reverse osmosis membranes, Proshare's breakthrough shines in four pivotal domains:
Innovative Self-Assembled Nanocomposite Films
By harnessing nano-scale precision control and nano-doping alteration, we have crafted ultra-thin, highly organized separation layers through the marvel of polymer interface nanotechnology. This innovation addresses and overcomes the traditional polyamide membranes' challenges in uniform thickness and material diversity.
Significant Boost in Water Flux and Energy Efficiency
Our meticulous optimization of the layer-by-layer self-assembly process ensures precise control of the functional layer's thickness, achieving a groundbreaking reduction-over 3x thinner than traditional membranes. This culminates in an outstanding >3x increase in water flux and a remarkable 30% reduction in energy consumption.
Advanced Polymer Materials with Remarkable Chemical Stability
Surpassing polyamide, our team employs cutting-edge hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids, which exhibit exceptional resistance to oxidation (withstanding exposure to 10 ppm of chlorine) and unmatched pH tolerance (maintaining stability in a pH range of 1-12).
