1. To ensure the pinnacle of performance, permeate flow rate and stabilized salt rejection are founded on 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 is initiated.
2. Kindly note, the permeate flow may vary within a range of +/-15%, and the final water yield might experience further variations due to
the heat treatment processes involved.

ProshareTeam's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
ProshareOur innovative team has reached a significant milestone by pioneering cutting-edge reverse osmosis membranes. By mastering polymer interface nano-self-assembly technology, we have shattered the conventional constraints of membrane development with not one, but two groundbreaking advancements:
Ultra-Thin Separation Layer: Utilizing the advanced polymer interface nanotechnology, we have masterfully engineered a separation layer that is remarkably three times thinner than traditional polyamide thin films, which were limited to 100 nm. This extraordinary reduction in thickness significantly boosts water flux, bringing about an impressive enhancement in permeability.
Enhanced Performance: By seamlessly integrating nanoparticles with specialized hydrophilic polymers, we have achieved monumental advancements in elevating the membrane's hydrophilicity, anti-fouling capabilities, durability, and resistance to oxidation.
Compared to traditional polyamide reverse osmosis membranes,Proshare's revolutionary innovation sets new benchmarks in four key dimensions:
Self-Assembled Nanocomposite Films
The synthesis of nano-scale precision control with nano-doping modification heralds the creation of ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This transformative approach transcends the limitations in thickness uniformity and material diversity typical of conventional polyamide membranes.
Enhanced Water Flux and Energy Efficiency
Through the meticulous optimization of the layer-by-layer self-assembly process, we have precisely crafted the functional layer thickness, achieving a staggering 3x reduction compared to traditional membranes. This strategic advancement leads to >3x higher water flux and 30% lower energy consumption.
Revolutionary Polymer Materials with Superior Chemical Stability
Breaking away from polyamide, our team employs state-of-the-art hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These pioneering materials exhibit exceptional oxidation resistance (withstanding 10 ppm chlorine exposure) and pH tolerance (stabilizing within the 1-12 pH range).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, engineered with a contact angle of less than 10° and reinforced by nanoparticles, reduces the tendency for organic fouling by 50%. This cutting-edge innovation extends chemical cleaning cycles from 3 months to 6 months, while dramatically reducing maintenance costs by 40%.
