Successful Cases Reference
Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
The application of desalination membranes on international luxury cruise ships has historically been dominated by a few international brands. The quality of feed water, such as salinity and temperature, fluctuates with the cruise ship's journey. Therefore, the membranes must adapt to different conditions while ensuring stable water production to meet the needs of ocean-going vessels.
PSI MEMBRANE Pro-HR-SW seawater desalination membranes demonstrated superior performance in both desalination rate and stable water production. The water quality produced by these membranes met the stringent requirements of the cruise ship.
This remarkable result led to the replacement of desalination membranes on three additional cruise ships. Proshare's success in this venture establishes it as the first national brand to win international luxury cruise ship orders for desalination RO membranes.

Proshare Revolutionary Breakthrough in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare team has ingeniously pioneered a new era of reverse osmosis membranes using advanced polymer interface nano-self-assembly technology, transcending traditional limitations through two landmark advancements:
Ultra-Thin Separation Layer: Harnessing polymer interface nanotechnology, the team achieved a monumental reduction in the separation layer's thickness, making it at least three times thinner than the conventional polyamide films (previously bound to 100 nm). This remarkable breakthrough propels water flux to new heights, dramatically boosting permeability.
Enhanced Performance: Through the innovative use of nanoparticles and specialized hydrophilic polymers, we've realized groundbreaking advancements in hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance of our membranes.
In comparison with traditional polyamide reverse osmosis membranes, Proshare's innovation showcases breakthroughs across four pivotal areas:
Self-Assembled Nanocomposite Films
By integrating nano-scale precision control with nano-doping modification, ultra-thin, highly ordered separation layers are crafted via polymer interface nanotechnology. This approach transcends the confines of conventional polyamide membranes in thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, precise control is achieved over functional layer thickness, resulting in a 3x reduction compared to traditional membranes. This culminates in >3x higher water flux and 30% lower energy consumption.
Cutting-Edge Polymer Materials with Unmatched Chemical Stability
Moving beyond polyamide, the team embraces advanced hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These materials offer exceptional oxidation resistance (withstanding 10 ppm chlorine exposure) and pH resilience (maintaining stability across a 1-12 pH range).
State-of-the-Art Anti-Fouling Surface Engineering
