1. To guarantee top-tier performance, the permeate flow rate and stabilized salt rejection are derived from the following meticulously verified 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 process.
2. Be aware that the permeate flow variation range is +/-15%, and the final water yield may show further variation due to
the heat treatment process involved.

ProshareTeam's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
ProshareOur team has pioneered an extraordinary leap forward with the creation of state-of-the-art reverse osmosis membranes. By harnessing the cutting-edge polymer interface nano-self-assembly technology, we have shattered the conventional hurdles in membrane development, achieving two monumental advancements that set a new benchmark in the industry:
Ultra-Thin Separation Layer: Through the advanced deployment of polymer interface nanotechnology, our team has remarkably engineered a separation layer that is at least three times thinner than standard polyamide thin films, which were previously limited to 100 nm. This groundbreaking reduction significantly boosts water flux, resulting in an impressive enhancement in permeability.
Enhanced Performance: By introducing cutting-edge nanoparticles alongside specialized hydrophilic polymers, we have made pioneering strides in elevating the membrane's hydrophilicity, anti-fouling capabilities, durability, and resistance to oxidation, setting a new standard for membrane performance.
Compared to traditional polyamide reverse osmosis membranes,Proshare's innovation manifests in groundbreaking breakthroughs across four key dimensions:
Self-Assembled Nanocomposite Films
The synergy of nano-scale precision control with nano-doping modification facilitates the creation of ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This revolutionary approach surpasses the limitations of thickness uniformity and material diversity found in conventional polyamide membranes.
Enhanced Water Flux and Energy Efficiency
By meticulously refining the layer-by-layer self-assembly process, we have precisely regulated the functional layer thickness, achieving an astonishing 3x reduction compared to traditional membranes. This strategic advancement results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Departing from traditional polyamide, our team employs advanced hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These state-of-the-art materials exhibit unparalleled oxidation resistance (enduring 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 less than 10° and strengthened by nanoparticle reinforcement, dramatically reduces the propensity for organic fouling by 50%. This innovation extends chemical cleaning cycles from 3 months to 6 months, while significantly cutting maintenance costs by 40%.
