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 by Our Team in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our innovative team has masterfully developed a groundbreaking new generation of reverse osmosis membranes using cutting-edge polymer interface nano-self-assembly technology. This breakthrough triumphs over the constraints of conventional reverse osmosis membrane development with two significant advancements:
Revolutionary Ultra-Thin Separation Layer: Utilizing state-of-the-art polymer interface nanotechnology, our team has remarkably minimized the separation layer thickness to at least thrice thinner than the traditional polyamide thin film, previously restricted to 100 nm. This innovation markedly boosts water flux, resulting in a dramatic enhancement in permeability.
Supercharged Enhanced Performance: The integration of nanoparticles and specialized hydrophilic polymers has spearheaded groundbreaking improvements in the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance.
In comparison to traditional polyamide reverse osmosis membranes, Proshare's pioneering innovation showcases breakthroughs across four critical dimensions:
