Proshare Revolutionary Milestones in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare proudly presents its trailblazing innovation: a new era of reverse osmosis membranes engineered through advanced polymer interface nano-self-assembly technology. This breakthrough surpasses the limitations of conventional reverse osmosis membranes with two key advancements:
Ultralight and Efficient Separation Layer: Utilizing state-of-the-art polymer interface nanotechnology, the team has skillfully reduced the separation layer's thickness to an extraordinary degree-at least three times thinner than standard polyamide thin films (previously limited to 100 nm). This extraordinary progress significantly increases water flux, yielding a substantial boost in permeability.
Enhanced Performance and Long-lasting Durability: The integration of nanoparticles with specialized hydrophilic polymers initiates transformative strides in membrane hydrophilicity, anti-fouling capability, durability, and resistance to oxidation.
Compared to traditional polyamide reverse osmosis membranes, Prosharehas achieved remarkable advancements in four critical areas:
Innovative Self-Assembled Nanocomposite Film Technology
By seamlessly blending nanometer-scale precision control with nano-doping modification, we create ultra-thin, meticulously arranged separation layers using polymer interface nanotechnology. This method transcends traditional polyamide membrane limitations in both thickness uniformity and material diversity.
Enhanced Water Flux Coupled with Superior Energy Efficiency
By mastering the layer-by-layer self-assembly process, the thickness of the functional layer is precisely controlled, accomplishing an impressive 3x reduction compared to traditional membranes. This groundbreaking achievement results in over 3x greater water flux and 30% reduction in energy consumption.
Revolutionary Polymer Materials with Exceptional Chemical Stability
Moving beyond polyamide boundaries, the team employs cutting-edge hydrophilic polymers (e.g., modified polysulfones) combined with ceramic-organic hybrids. These materials offer unmatched oxidation resistance (enduring exposure to 10 ppm chlorine) and pH resilience (maintaining stability over a pH range of 1 to 12).
Expertise in Anti-Fouling Surface Mastery
The superhydrophilic surface (contact angle <10°), reinforced by nanoparticles, reduces organic fouling tendency by 50%, extending chemical cleaning intervals from 3 to 6 months and cutting maintenance costs by 40%.
