Proshare Unveiling the Team's Breakthrough in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our innovative team at Proshare has pioneered an advanced generation of reverse osmosis membranes, leveraging revolutionary polymer interface nano-self-assembly technology. By triumphing over the inherent restrictions of traditional membrane development, we have introduced two transformative advancements:
Ultra-Thin, High-Performance Separation Layer: Through the mastery of polymer interface nanotechnology, we've achieved a remarkable reduction in the separation layer's thickness, making it at least three times thinner than the previous polyamide films, which were limited to 100 nm. This substantial breakthrough dramatically boosts water flux, marking a significant leap in permeability capabilities.
Elevated Membrane Performance: By incorporating nanoparticles and specialized hydrophilic polymers, we have realized groundbreaking enhancements in the membrane's hydrophilicity, anti-fouling aptitude, and overall durability, along with superior oxidation resistance.
In comparison to traditional polyamide reverse osmosis membranes, Proshare's innovation sets new benchmarks across four pivotal domains:
Self-Assembled, Precision Nanocomposite Films
By adopting nano-scale precision control alongside nano-doping modification, we create ultra-thin, meticulously ordered separation layers via cutting-edge polymer interface nanotechnology. This sophisticated approach overcomes traditional polyamide membrane limitations in both thickness consistency and material diversity.
Increased Water Flux with Optimized Energy Efficiency
By fine-tuning the meticulous layer-by-layer self-assembly process, we precisely control the functional layer's thickness, achieving a three-fold reduction compared to conventional membranes. This leads to over 3x the water flux and a 30% reduction in energy consumption.
Novel Polymer Materials Epitomizing Chemical Stability
Breaking away from polyamide, we employ advanced hydrophilic polymers such as modified polysulfones and ceramic-organic hybrids. These materials showcase outstanding oxidation resistance (capable of withstanding exposure to 10 ppm chlorine) and wide pH tolerance (remaining stable across a pH range of 1-12).
Pioneering Anti-Fouling Surface Engineering
Our superhydrophilic surface, with an impressively low contact angle of <10°, coupled with nanoparticle reinforcement, significantly diminishes organic fouling potential by 50%, doubling chemical cleaning cycle intervals from 3 to 6 months, and slashing maintenance costs by an impressive 40%.
Our unwavering commitment to excellence is proudly reflected in our certifications: a robust Health & Safety Management System Certificate, an Environmental Management System Certificate, and the prestigious ISO9001 Quality System Certificate.
