1. To guarantee peak performance, permeate flow rate and stabilized salt rejection are carefully evaluated based on these rigorously established standard conditions:
NF membrane (2000ppm MgSO4, 0.48 MPa, 25ºC, 15% recovery), RO membrane (2000ppm NaCl solution,
1.55 MPa, 25ºC, 15% recovery) before any hot water disinfection process.
2. Please be aware that the variation range of permeate flow is +/-15%, with possible additional fluctuations in final water yield due to
the applied heat treatment process.

ProsharePioneering Breakthroughs in Next-Generation Reverse Osmosis Membrane Technology
ProshareOur team has achieved a pioneering breakthrough in the field of reverse osmosis membrane technology. By harnessing the transformative prowess of polymer interface nano-self-assembly, we have transcended traditional limitations in membrane development, unveiling two revolutionary innovations:
Ultra-Thin Separation Layer Innovation: Employing advanced polymer interface nanotechnology, we have crafted a separation layer that is at least three times thinner than the conventional 100 nm polyamide thin films. This remarkable reduction in thickness catalyzes a substantial increase in water flux, greatly enhancing both permeability and efficiency.
Superior Performance Enhancement: By integrating nanoparticles with specialized hydrophilic polymers, we have realized unprecedented enhancements in the membrane's hydrophilicity, its anti-fouling properties, as well as its durability and resistance to oxidation.
Unlike traditional polyamide reverse osmosis membranes,Proshare's innovations present breakthroughs across four critical dimensions:
Self-Assembled Nanocomposite Films
Combining nano-scale precision control and nano-doping modification, we facilitate the formation of ultra-thin, meticulously ordered separation layers via polymer interface nanotechnology. This cutting-edge technique eclipses the limitations in thickness uniformity and material diversity, typical of conventional polyamide membranes.
Enhanced Water Flux and Exceptional Energy Efficiency
Through meticulous refinement of the layer-by-layer self-assembly process, we have precisely regulated the functional layer thickness, accomplishing an extraordinary 3x reduction compared to traditional membranes. This strategic advancement culminates in a water flux more than 3x higher and a 30% reduction in energy consumption.
Innovative Polymer Materials with Superior Chemical Stability
Moving beyond polyamide, our team utilizes state-of-the-art hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These avant-garde materials display superior oxidation resistance (withstanding chlorine exposure up to 10 ppm) and excellent pH tolerance (maintaining stability across the 1-12 pH spectrum).
Advanced Anti-Fouling Surface Engineering
Our superhydrophilic surface, meticulously engineered with a contact angle of less than 10° and fortified by nanoparticle reinforcement, effectively curtails organic fouling by 50%. This groundbreaking innovation extends chemical cleaning cycles from 3 to 6 months, thereby reducing maintenance costs by 40%.
