1. To ensure optimal performance, permeate flow rate and stabilized salt rejection are based on rigorously tested standard conditions:
NF membrane (2000ppm MgSO4, 0.48 MPa, 25ºC, 15% recovery) and RO membrane (2000ppm NaCl solution,
1.55 MPa, 25ºC, 15% recovery) before any hot water disinfection process is applied.
2. It is important to note that the variation range of permeate flow is +/-15%, and the final water yield may fluctuate due to
the heat treatment process involved, ensuring adaptability and resilience.

ProshareTeam's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
ProshareOur team has pioneered an innovative breakthrough with the development of cutting-edge reverse osmosis membranes. Harnessing the power of polymer interface nano-self-assembly technology, we have overcome the typical barriers faced in traditional membrane development with two groundbreaking advancements:
Ultra-Thin Separation Layer: Through the sophisticated application of polymer interface nanotechnology, our team has succeeded in crafting a separation layer that is at least three times thinner than conventional polyamide thin films, previously constrained to 100 nm. This revolutionary reduction in thickness amplifies water flux, leading to a dramatic enhancement in permeability.
Enhanced Performance: By introducing nanoparticles along with specialized hydrophilic polymers, we have achieved groundbreaking strides in boosting the membrane's hydrophilicity, anti-fouling capabilities, durability, and resistance to oxidation.
Compared to traditional polyamide reverse osmosis membranes,Proshare's innovation manifests in breakthroughs across four pivotal aspects:
Self-Assembled Nanocomposite Films
The fusion of nano-scale precision control with nano-doping modification paves the way for the formation of ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This revolutionary method transcends the constraints in thickness uniformity and material diversity found in conventional polyamide membranes.
Enhanced Water Flux and Energy Efficiency
By meticulously optimizing 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 evolution results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
In a departure from polyamide, our team employs advanced hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These cutting-edge materials display superior oxidation resistance (withstanding 10 ppm chlorine exposure) and pH tolerance (stabilizing within the 1-12 pH range).
Anti-Fouling Surface Engineering
Our superhydrophilic surface, crafted with a contact angle less than 10° and fortified by nanoparticle reinforcement, reduces the propensity for organic fouling by 50%. This innovation prolongs chemical cleaning cycles from 3 months to 6 months, while slashing maintenance costs by 40%.
