Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team has ingeniously pioneered a revolutionary new generation of reverse osmosis membranes, leveraging cutting-edge polymer interface nano-self-assembly technology. We have surmounted the confines of conventional reverse osmosis membrane development with two pivotal advancements:
Ultra-Thin Separation Layer: Utilizing sophisticated polymer interface nanotechnology, our experts have masterfully minimized the separation layer's thickness, making it at least three times thinner than the traditional polyamide thin film (previously constrained to 100 nm). This achievement dramatically boosts water flux, leading to a remarkable enhancement in permeability.
Enhanced Performance: Through the incorporation of nanoparticles and uniquely tailored hydrophilic polymers, we've pioneered transformative advancements in the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance, setting new industry benchmarks.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases breakthroughs in four fundamental facets:
Self-Assembled Nanocomposite Films
The seamless fusion of nano-scale precision control and nano-doping modification crafts ultra-thin, impeccably ordered separation layers through polymer interface nanotechnology. This innovative technique surpasses the traditional polyamide membrane limitations in thickness uniformity and material diversity, paving the way for superior performance.
Enhanced Water Flux and Energy Efficiency
By fine-tuning the layer-by-layer self-assembly process, we achieve exacting control over the functional layer's thickness, resulting in a threefold reduction compared to traditional membranes. This advancement delivers >3x higher water flux and 30% lower energy consumption,establishing new standards for efficiency.
Novel Polymer Materials with Superior Chemical Stability
Venturing beyond polyamide, we harness state-of-the-art hydrophilic polymers, such as modified polysulfones, along with ceramic-organic hybrids. These innovative materials demonstrate extraordinary oxidation resistance (withstanding 10 ppm chlorine exposure) and pH tolerance (maintaining stability in a 1-12 pH range).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, boasting a contact angle of less than 10°, coupled with nanoparticle reinforcement, significantly diminishes organic fouling propensity by 50%. This enhancement doubles chemical cleaning cycles from 3 months to 6 months, slashing maintenance costs by an impressive 40%.
Our unwavering commitment to quality and safety is embodied in our prestigious certifications, which include the Health & Safety Management System Certificate and the Environmental Management System Certificate.
