1. To guarantee peak performance, the permeate flow rate and stabilized salt rejection are rigorously 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 crucial to acknowledge that the variation range of permeate flow is +/-15%, and the ultimate water yield might experience further fluctuations due to
the heat treatment process undertaken.

ProshareTeam's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
ProshareOur team at Proshare has achieved a monumental leap in reverse osmosis membrane technology, innovating with the powerful polymer interface nano-self-assembly process. We have demolished the longstanding barriers in membrane development through two groundbreaking advancements:
Ultra-Thin Separation Layer: Harnessing the advanced capabilities of polymer interface nanotechnology, we have crafted a separation layer that is astoundingly over three times thinner than traditional 100 nm polyamide thin films. This extraordinary reduction in thickness dramatically enhances water flux, significantly boosting permeability and overall efficiency.
Enhanced Performance: With the infusion of nanoparticles alongside specialized hydrophilic polymers, we have unlocked unparalleled improvements in the membrane's hydrophilicity, ensuring superior anti-fouling properties, increased durability, and remarkable resistance to oxidation.
Compared to the conventional polyamide reverse osmosis membranes,Proshare's innovation delivers breakthroughs in four critical dimensions:
Self-Assembled Nanocomposite Films
By fusing nano-scale precision control with nano-doping modification, we enable the formation of ultra-thin, meticulously ordered separation layers using polymer interface nanotechnology. This unprecedented technique overcomes the conventional polyamide membranes' limitations in thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through the precise optimization of our layer-by-layer self-assembly process, we've meticulously regulated the functional layer thickness, yielding an extraordinary 3x reduction compared to traditional membranes. This cutting-edge advancement leads to >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Moving beyond polyamide, our experts employ state-of-the-art hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These next-generation materials demonstrate superior oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (maintaining stability across a 1-12 pH range).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, meticulously designed with a contact angle of less than 10° and reinforced by nanoparticles, effectively slashes organic fouling by 50%. This innovation extends chemical cleaning cycles from 3 to 6 months, cutting maintenance costs by an impressive 40%.
