1. To maintain peak performance, the permeate flow rate and stabilized salt rejection are determined with rigorous precision based on these 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. Please be aware that the range of permeate flow variation is +/-15%, with potential additional fluctuations in the final water yield due to
the involved heat treatment process.

ProshareTeam's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
ProshareOur team has pioneered a groundbreaking advancement in reverse osmosis membrane technology. By harnessing the transformative power of polymer interface nano-self-assembly, we have overcome traditional challenges in membrane development through two revolutionary innovations:
Ultra-Thin Separation Layer: By ingeniously applying polymer interface nanotechnology, we crafted a separation layer remarkably at least three times thinner than conventional 100 nm polyamide thin films. This pivotal reduction in thickness significantly boosts water flux, thereby enhancing permeability and operational efficiency.
Enhanced Performance: By integrating nanoparticles with specialized hydrophilic polymers, our technology achieves unparalleled advancements in hydrophilicity, anti-fouling properties, durability, and oxidation resistance of the membrane.
Compared to traditional polyamide reverse osmosis membranes,Proshare's innovation manifests in breakthroughs across four pivotal aspects:
Self-Assembled Nanocomposite Films
Through nano-scale precision control combined with nano-doping modification, we create ultra-thin, meticulously ordered separation layers via polymer interface nanotechnology. This pioneering technique surpasses previous limitations in thickness uniformity and material diversity seen in conventional polyamide membranes.
Enhanced Water Flux and Energy Efficiency
With careful optimization of the layer-by-layer self-assembly process, we precisely regulate the functional layer thickness, achieving an extraordinary reduction of over 3x 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
By departing from polyamide, our team employs state-of-the-art hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These advanced materials showcase superior oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (stabilizing effectively within the 1-12 pH range).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, meticulously engineered with a contact angle less than 10° and reinforced by nanoparticles, effectively reduces organic fouling by 50%. This innovation extends chemical cleaning cycles from 3 to 6 months, leading to a 40% reduction in maintenance costs.
