Proshare Revolutionary Achievements in Advanced Reverse Osmosis Membrane Technology
Proshare proudly introduces its groundbreaking innovation: a novel generation of reverse osmosis membranes crafted through polymer interface nano-self-assembly technology. This advancement triumphs over traditional reverse osmosis membrane limitations with two pivotal breakthroughs:
Ultralight Separation Layer: Harnessing cutting-edge polymer interface nanotechnology, the team has ingeniously thinned the separation layer to a remarkable extent-at least three times slimmer than conventional polyamide thin films (previously restricted to 100 nm). This monumental leap dramatically amplifies water flux, delivering a significant rise in permeability.
Enhanced Performance and Durability: The infusion of nanoparticles alongside specialized hydrophilic polymers catalyzes transformative advancements in membrane hydrophilicity, anti-fouling prowess, durability, and oxidation resistance.
In comparison to traditional polyamide reverse osmosis membranes, Prosharehas achieved breakthroughs in four essential domains:
Self-Assembled Nanocomposite Film Technology
Through the seamless fusion of nanometer-scale precision control with nano-doping modification, we innovate ultra-thin, meticulously ordered separation layers via polymer interface nanotechnology. This method surpasses conventional polyamide membrane constraints in both thickness uniformity and material variety.
Enhanced Water Flux and Superior Energy Efficiency
By mastering the layer-by-layer self-assembly process, the thickness of the functional layer is precisely regulated, achieving a remarkable 3x reduction relative to traditional membranes. This breakthrough results in over 3x higher water flux and 30% lower energy consumption.
Innovative Polymer Materials with Exceptional Chemical Stability
Stepping beyond polyamide boundaries, the team employs state-of-the-art hydrophilic polymers (e.g., modified polysulfones) coupled with ceramic-organic hybrids. These materials provide unparalleled oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH resilience (maintaining stability across a pH range of 1 to 12).
Anti-Fouling Surface Mastery
The superhydrophilic surface (contact angle <10°), enhanced by nanoparticle reinforcement, diminishes organic fouling propensity by 50%, prolonging chemical cleaning intervals from 3 to 6 months and slashing maintenance costs by 40%.
Our commitment to excellence is underscored by an array of prestigious certifications: Health & Safety Management System Certificate, Environmental Management System Certificate, and the ISO9001 Quality System Certificate, all attesting to our unwavering dedication to maintaining the highest standards.
