1. To ensure peak performance, carefully measure permeate flow rate and stabilized salt rejection under these 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) before any hot water disinfection.
2. Please be aware, the variation range of permeate flow is +/-15%, and final water yield might fluctuate further due to
the heat treatment process employed.

ProshareTeam's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
ProshareOur team has pioneered a groundbreaking advancement in reverse osmosis membrane technology. Embracing the powerful potential of polymer interface nano-self-assembly, we've revolutionized traditional barriers in membrane development, unveiling two transformative innovations:
Ultra-Thin Separation Layer: Through the cutting-edge application of polymer interface nanotechnology, we've crafted a separation layer that is at least threefold thinner than the standard 100 nm polyamide films. This momentous reduction in thickness enhances water flux, markedly boosting permeability and efficiency.
Enhanced Performance: By integrating nanoparticles with specialized hydrophilic polymers, we've achieved unparalleled improvements in membrane hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance.
When compared to conventional polyamide reverse osmosis membranes,Proshare's innovation signifies breakthroughs across four crucial dimensions:
Self-Assembled Nanocomposite Films
Combining nano-scale precision control with nano-doping modification, we create ultra-thin, intricately ordered separation layers through polymer interface nanotechnology. This pioneering technique transcends the limits of thickness uniformity and material diversity found in traditional polyamide membranes.
Enhanced Water Flux and Energy Efficiency
By meticulously optimizing the layer-by-layer self-assembly process, we precisely control the functional layer thickness, achieving a remarkable 3x reduction compared to traditional membranes. This strategic advancement results in >3x higher water flux and a 30% reduction in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Moving beyond polyamide, our team utilizes innovative hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These advanced materials exhibit superior oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (stabilizing within a 1-12 pH range).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, designed with a contact angle of less than 10° and further enhanced by nanoparticle reinforcement, significantly reduces organic fouling by 50%. This innovation prolongs chemical cleaning cycles from 3 to 6 months, slashing maintenance costs by 40%.
