1. To guarantee peak performance, the permeate flow rate and stabilized salt rejection are determined 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) prior to any hot water disinfection.
2. Please be aware that the variation range of permeate flow is +/-15%, and subsequent water yield might experience further variability due to
the heat treatment process applied.

ProshareTeam's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
ProshareOur team has achieved a groundbreaking leap forward by developing state-of-the-art reverse osmosis membranes. Through the innovative application of polymer interface nano-self-assembly technology, we have triumphantly overcome the standard hurdles in traditional membrane design with two revolutionary breakthroughs:
Ultra-Thin Separation Layer: By masterfully leveraging polymer interface nanotechnology, our team has crafted an ultra-thin separation layer that is a remarkable three times thinner than the conventional 100 nm polyamide thin films. This unprecedented thinning of the layer significantly boosts water flux, resulting in a remarkable enhancement in permeability.
Enhanced Performance: By skillfully integrating nanoparticles with specialized hydrophilic polymers, we have made tremendous strides in elevating the membrane's hydrophilicity, anti-fouling properties, durability, and oxidation resistance.
Compared to conventional polyamide reverse osmosis membranes,Proshare's innovation is distinguished by breakthroughs across four essential dimensions:
Self-Assembled Nanocomposite Films
By seamlessly fusing nano-scale precision control with nano-doping modification, we pave the way for crafting ultra-thin, meticulously ordered separation layers through polymer interface nanotechnology. This transformative method breaks through the barriers of thickness uniformity and material diversity typical in conventional polyamide membranes.
Enhanced Water Flux and Energy Efficiency
Through the precise optimization of the layer-by-layer self-assembly process, we regulate the functional layer thickness, achieving a stunning 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
In an innovative departure from polyamide, we employ advanced hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These state-of-the-art materials exhibit superior oxidation resistance (withstanding exposure up to 10 ppm chlorine) and pH tolerance (stabilizing effectively within the 1-12 pH range).
