1. The permeate flow rate and stabilized salt rejection are derived from these rigorous standard test conditions:
NF membrane (2000ppm MgSO4, 0.48 MPa, 25ºC, 15% recovery), RO membrane (2000ppm NaCl solution,
1.55 MPa, 25ºC, 15% recovery) conducted prior to any hot water disinfection process.
2. The variation range of permeate flow is +/-15%, with potential for greater fluctuations in final water yield due to

Proshare Pioneering Breakthroughs in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our team has achieved remarkable innovations in creating a new generation of reverse osmosis membranes utilizing polymer interface nano-self-assembly technology. These advancements have surpassed the traditional membrane development constraints through two transformative innovations:
Ultra-Thin Separation Layer Innovation: By harnessing the power of polymer interface nanotechnology, Proshare has successfully diminished the thickness of the separation layer, achieving a remarkable reduction to at least three times thinner than traditional polyamide thin films (previously capped at 100 nm). This pioneering breakthrough greatly amplifies water flux, delivering significant improvements in permeability.
Unparalleled Performance Enhancement: Thanks to the incorporation of nanoparticles and unique hydrophilic polymers, we have achieved revolutionary strides in enhancing membrane hydrophilicity, fortifying anti-fouling capabilities, boosting durability, and enhancing oxidation resistance.
In contrast to traditional polyamide reverse osmosis membranes, Prosharehas pioneered advancements in four fundamental areas:
Self-Assembled Nanocomposite Films
By integrating nano-scale precision control with nano-doping modification, we create ultra-thin, highly ordered separation layers through polymer interface nanotechnology. This innovative method overcomes the conventional polyamide membranes' limitations in thickness uniformity and material diversity.
Increased Water Flux Coupled with Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, we precisely control the functional layer thickness, achieving a threefold reduction compared to traditional membranes. This innovation results in >3x enhanced water flux and a remarkable 30% decrease in energy consumption.
Innovative Polymer Materials with Exceptional Chemical Stability
Moving beyond conventional polyamide, our team employs advanced hydrophilic polymers (e.g., modified polysulfones) alongside ceramic-organic hybrids. These materials showcase outstanding oxidation resistance (withstanding chlorine exposure up to 10 ppm) and robust pH tolerance (remaining stable across a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
Featuring a superhydrophilic surface (contact angle <10°) reinforced with nanoparticles, our technology reduces organic fouling potential by 50%. This advancement extends the interval between chemical cleaning cycles from 3 months to 6 months, substantially lowering maintenance costs by 40%.
