Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our team at Proshare has ingeniously developed a cutting-edge new generation of reverse osmosis membranes utilizing the pioneering concept of polymer interface nano-self-assembly technology. This remarkable innovation shatters the traditional developmental constraints of reverse osmosis membranes through two pivotal advancements:
Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, the team has achieved a groundbreaking reduction in the separation layer's thickness, making it at least three times thinner than the conventional 100 nm polyamide thin film. This extraordinary achievement significantly escalates water flux, paving the way for a notable leap in permeability.
Enhanced Performance: By incorporating nanoparticles and specialized hydrophilic polymers, the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance have undergone revolutionary improvements, establishing new standards of excellence in these domains.
Compared to traditional polyamide reverse osmosis membranes, Proshare's groundbreaking innovation heralds significant advancements in four critical areas:
Self-Assembled Nanocomposite Films
Through the sophisticated integration of nano-scale precision control and nano-doping modification, we create ultra-thin, highly ordered separation layers using polymer interface nanotechnology. This innovative approach surmounts the constraints of conventional polyamide membranes, achieving unmatched thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Skillfully optimizing the layer-by-layer self-assembly process allows for precise control of the functional layer's thickness, resulting in a remarkable 3-fold reduction compared to traditional membranes. This breakthrough offers >3x higher water flux and 30% lower energy consumptionfor maximum efficiency.
Novel Polymer Materials with Superior Chemical Stability
Moving beyond the realm of polyamide, our team employs advanced hydrophilic polymers such as modified polysulfones and ceramic-organic hybrids. These materials exhibit unparalleled oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (stable across a wide pH range of 1-12).
Anti-Fouling Surface Engineering
With an exceptionally superhydrophilic surface (contact angle <10°), reinforced by nanoparticles, the propensity for organic fouling is halved, extending chemical cleaning cycles from 3 to 6 months and slashing maintenance costs by 40%, ultimately offering unparalleled operational efficiency.
Our unwavering commitment to excellence is showcased through our prestigious certifications: the Health & Safety Management System Certificate, the Environmental Management System Certificate, and the ISO 9001 Quality System Certificate. Each of these accolades is a testament to our dedication to maintaining top-tier standards of safety, sustainability, and quality in all our processes.
