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 have proven to deliver exceptional performance in both desalination rate and consistent water output. These membranes produce water that meets the stringent quality standards required by luxury cruise ships.
This outstanding achievement led to the installation of desalination membranes on three more cruise ships. Proshare's success in this endeavor establishes it as the first national brand to secure international luxury cruise ship orders for desalination RO membranes.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our cutting-edge team has innovatively crafted a revolutionary generation of reverse osmosis membranes, cleverly utilizing polymer interface nano-self-assembly technology. This breakthrough triumphantly overcomes traditional constraints, marking two significant advancements:
Ultra-Thin Separation Layer: Utilizing polymer interface nanotechnology, the team masterfully minimized the separation layer's thickness to at least one-third of conventional polyamide thin films (previously constrained to 100 nm). This remarkable innovation significantly elevates water flux, leading to a substantial enhancement in permeability.
Enhanced Performance: By incorporating nanoparticles and uniquely tailored hydrophilic polymers, groundbreaking improvements have been achieved in the membrane's hydrophilicity, anti-fouling properties, long-lasting durability, and superior oxidation resistance.
In comparison to traditional polyamide reverse osmosis membranes, Proshare's innovation demonstrates revolutionary breakthroughs in four pivotal areas:
Self-Assembled Nanocomposite Films
Through the integration of nano-scale precision and nano-doping modification, ultra-thin, highly ordered separation layers are achieved via polymer interface nanotechnology. This innovative approach triumphantly overcomes conventional polyamide membranes' limitations in thickness consistency and material variety.
Enhanced Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, the functional layer's thickness is precisely managed, achieving a 3x reduction when compared to traditional membranes. This results in >3x amplified water flux and a 30% decrease in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Surpassing polyamide, the team employs advanced hydrophilic polymers (e.g., modified polysulfones) and ceramic-organic hybrids. These cutting-edge materials exhibit exceptional oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (remaining stable across a pH range of 1-12).
Anti-Fouling Surface Engineering
The remarkably superhydrophilic surface (contact angle <10°) combined with nanoparticle fortification slashes organic fouling propensity by 50%, doubling chemical cleaning cycles from 3 to 6 months and reducing maintenance costs by 40%
