1. To guarantee peak performance, the permeate flow rate and stabilized salt rejection are based on 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) before any hot water disinfection process.
2. Please be advised, the variation range of permeate flow is +/-15%, and the final water yield may vary further due to
the heat treatment processes applied.

ProshareOur Team's Breakthrough in Cutting-Edge Reverse Osmosis Membrane Technology
ProshareOur team has achieved a groundbreaking milestone in reverse osmosis membrane technology. By harnessing the transformative potential of polymer interface nano-self-assembly, we have not just crossed but leapt over traditional developmental barriers with two pioneering innovations:
Ultra-Thin Separation Layer: Utilizing advanced polymer interface nanotechnology, we have crafted a separation layer that is an astounding three times thinner than the standard 100 nm polyamide thin films. This remarkable reduction in thickness significantly boosts water flux, thereby greatly enhancing both permeability and efficiency.
Enhanced Performance: Through the strategic introduction of nanoparticles combined with specialized hydrophilic polymers, we have realized extraordinary advancements in the membrane's hydrophilicity, resistance to fouling, exceptional durability, and robust oxidation resistance.
In comparison to traditional polyamide reverse osmosis membranes,Proshare's innovation showcases breakthroughs across four critical dimensions:
Self-Assembled Nanocomposite Films
By integrating nano-scale precision control with nano-doping modification, we enable the creation of ultra-thin, exquisitely ordered separation layers via polymer interface nanotechnology. This groundbreaking approach outstrips the limitations in thickness uniformity and material diversity inherent in conventional 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 a remarkable 3x reduction compared to traditional membranes. This strategic enhancement leads to >3x increased water flux coupled with a 30% reduction in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Moving beyond polyamide, our team employs cutting-edge hydrophilic polymers (such as modified polysulfones) along with ceramic-organic hybrids. These avant-garde materials demonstrate unparalleled resistance to oxidation (withstanding exposure to 10 ppm chlorine) and pH resilience (maintaining stability within the 1-12 pH range).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, engineered with a contact angle less than 10° and reinforced by nanoparticles, effectively diminishes organic fouling by 50%. This innovation lengthens chemical cleaning cycles from 3 to 6 months, trimming maintenance costs by an impressive 40%.
