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 long been dominated by a few global giants. Given the varying quality of feed water, including factors like salinity and temperature that change with the cruise's path, it's crucial for the membranes to adapt to these dynamic conditions while maintaining consistent water output, thus fulfilling the demands of ocean-bound vessels.
PSI MEMBRANE Pro-HR-SW seawater desalination membranes have showcased exceptional performance, excelling in both the rate of desalination and consistent water output. The water produced by these membranes meets the rigorous standards required by luxury cruise ships.
This outstanding achievement prompted the replacement of desalination membranes on three more cruise ships. Proshare's triumph in this endeavor marks it as the pioneering 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 The Proshare team has masterfully pioneered a revolutionary generation of reverse osmosis membranes, harnessing the power of polymer interface nano-self-assembly technology. This remarkable innovation overcomes the traditional barriers in reverse osmosis membrane development with two transformative advancements:
Ultra-Thin Separation Layer: Utilizing cutting-edge polymer interface nanotechnology, the team has astonishingly refined the separation layer, making it at least three times thinner than the traditional polyamide thin film, which was previously constrained to 100 nm. This extraordinary breakthrough propels water flux to new heights, markedly enhancing permeability.
Enhanced Performance: The strategic integration of nanoparticles and advanced hydrophilic polymers has catalyzed unprecedented enhancements in the membrane's hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance, setting new standards in membrane technology.
Compared to traditional polyamide reverse osmosis membranes, Proshare's groundbreaking innovation manifests breakthroughs in four pivotal aspects:
Self-Assembled Nanocomposite Films
By employing nano-scale precision control and nano-doping modification, Proshare has created ultra-thin, highly ordered separation layers through polymer interface nanotechnology. This approach triumphs over the limitations in thickness uniformity and material diversity of conventional polyamide membranes.
Enhanced Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, the functional layer thickness is finely controlled, achieving a remarkable 3x reduction compared to traditional membranes. This results in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Pioneering beyond polyamide, the team employs cutting-edge advanced hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These materials showcase exceptional oxidation resistance (withstanding exposure to 10 ppm chlorine) and pH tolerance (maintaining stability across a pH range of 1-12).
Anti-Fouling Surface Engineering
The integration of a superhydrophilic surface (with contact angle <10°) and nanoparticle reinforcement significantly reduces organic fouling propensity by 50%, extending chemical cleaning cycles from 3 months to an impressive 6 months, thereby reducing maintenance costs by 40%.
