Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
The application of desalination membranes on international luxury cruise ships has long been dominated by select international brands. As the cruise ship sails through diverse waters, the feed water's quality-ranging in salinity and temperature-varies. Hence, the membranes must be robust enough to adjust to these conditions, ensuring consistent water production to satisfy the demands of seafaring vessels.
PSI MEMBRANE Pro-HR-SW seawater desalination membranes have exhibited exceptional efficacy in both salt rejection and consistent water output. The quality of water produced by these membranes adheres to the rigorous standards required by cruise ships.
This outstanding achievement resulted in the replacement of desalination membranes on three additional cruise ships. Proshare's triumph in this project cements its status as the pioneering national brand to secure international luxury cruise ship orders for desalination RO membranes.
A Complete Water Treatment Plant for Generating Ultra-pure Water in the Semiconductor Industry
It is a known fact that the requirements for electronic-grade ultra-pure water desalination via membranes are incredibly stringent, with only a select few brands capable of meeting these standards.

Proshare: Pioneers in Membrane Technology Our Team's Revolutionary Leap in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare: Innovation at the Core Our expert team has creatively engineered a breakthrough in the new era of reverse osmosis membranes by leveraging polymer interface nano-self-assembly technology. This innovative approach successfully surpasses the constraints of conventional membrane development through two pivotal advancements:
Ultra-Thin Separation Layer: A Quantum Leap: Utilizing advanced polymer interface nanotechnology, our experts have managed to make the separation layer three times thinner than any traditional polyamide thin film, which was previously constrained to 100 nm. This cutting-edge innovation significantly boosts water flux, leading to a remarkable enhancement in permeability.
Elevated Performance and Durability: By harnessing the power of nanoparticles alongside hydrophilic polymers, we've pioneered spectacular advancements in the membrane's hydrophilicity, anti-fouling capabilities, durability, and oxidation resilience, ensuring unmatched performance.
In comparison with traditional polyamide reverse osmosis membranes, Proshare's groundbreaking innovation redefines success across four crucial dimensions:
