1. To secure optimal performance, the permeate flow rate and stabilized salt rejection are carefully calibrated based on the following rigorously tested standard conditions:
NF membrane (2000ppm MgSO4, 0.48 MPa, 25ºC, 15% recovery), RO membrane (2000ppm NaCl solution,
1.55 MPa, 25ºC, 15% recovery) prior to any hot water disinfection.
2. Please note, the variation range of permeate flow is +/-15%, and the final water yield may experience additional fluctuations due to
the intricate heat treatment process involved.

ProshareTeam's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
ProshareOur team has pioneered a groundbreaking advancement in reverse osmosis membrane technology. By harnessing the transformative power of polymer interface nano-self-assembly, we have transcended traditional barriers in membrane innovation with two monumental breakthroughs:
Ultra-Thin Separation Layer: Through the advanced application of polymer interface nanotechnology, we have crafted a separation layer that is an astounding three times thinner than conventional 100 nm polyamide thin films. This monumental reduction in thickness elevates water flux, significantly amplifying permeability and efficiency.
Enhanced Performance: By integrating nanoparticles with specialized hydrophilic polymers, we have realized exceptional advancements in the membrane's hydrophilicity, resistance to fouling, durability, and ability to withstand oxidation.
Compared to traditional polyamide reverse osmosis membranes,Proshare's innovation is marked by groundbreaking achievements across four critical dimensions:
Self-Assembled Nanocomposite Films
Utilizing nano-scale precision control combined with nano-doping modification, we form ultra-thin, meticulously ordered separation layers using polymer interface nanotechnology. This revolutionary method surpasses the limitations of thickness uniformity and material variety found in conventional polyamide membranes.
Enhanced Water Flux and Energy Efficiency
Through the meticulous optimization of the layer-by-layer self-assembly process, we have precisely calibrated the functional layer thickness, achieving an extraordinary 3x reduction compared to traditional membranes. This strategic leap results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Departing from polyamide, our team uses state-of-the-art hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These innovative materials exhibit unparalleled oxidation resistance (withstanding 10 ppm chlorine exposure) and pH tolerance (maintaining stability within the 1-12 pH range).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, engineered with a contact angle of less than 10° and reinforced by nanoparticles, effectively diminishes organic fouling by 50%. This innovation extends chemical cleaning cycles from 3 to 6 months, reducing maintenance costs by 40%.
