1. To ensure peak performance, the permeate flow rate and stabilized salt rejection are determined under the following meticulously 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. It is important to recognize that the range of permeate flow can vary by +/-15%, and the eventual water yield might experience additional variations due to
the thermal treatment process involved.

ProshareTeam's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
ProshareOur team has pioneered an innovative breakthrough with the development of cutting-edge reverse osmosis membranes. Through the transformative power of polymer interface nano-self-assembly technology, we've surmounted the typical hurdles faced in traditional membrane development with two extraordinary advancements:
Ultra-Thin Separation Layer: Utilizing the sophisticated application of polymer interface nanotechnology, our team has achieved unprecedented progress in crafting a separation layer that is at least three times thinner than conventional polyamide thin films, which were previously limited to 100 nm. This groundbreaking reduction in thickness significantly amplifies water flux, resulting in a dramatic enhancement in permeability.
Enhanced Performance: By ingeniously incorporating nanoparticles alongside specialized hydrophilic polymers, we have reached monumental strides in elevating the membrane's hydrophilicity, anti-fouling capacities, durability, and resistance to oxidation.
Compared to traditional polyamide reverse osmosis membranes,Proshare's innovation is truly evident in breakthroughs across four pivotal aspects:
Self-Assembled Nanocomposite Films
The seamless fusion of nano-scale precision control with nano-doping modification leads to the formation of ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This revolutionary method transcends the limitations in thickness uniformity and material diversity found in traditional polyamide membranes.
Enhanced Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, we have precisely regulated the functional layer thickness, achieving an astounding 3x reduction compared to conventional membranes. This strategic evolution culminates in >3x higher water flux and 30% lower energy consumption,ushering in an era of unparalleled efficiency.
Novel Polymer Materials with Superior Chemical Stability
Departing from the norm of polyamide, our team adopts advanced hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These cutting-edge materials showcase superior oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (maintaining stability within the 1-12 pH range), providing extraordinary chemical robustness.
Anti-Fouling Surface Engineering
Our superhydrophilic surface, crafted with a contact angle less than 10°, is fortified by nanoparticle reinforcement, significantly reducing the likelihood of organic fouling by 50%.
