Successful Cases Reference
Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
Historically, the application of desalination membranes on international luxury cruise ships has been dominated by prominent global brands. As cruise ships traverse diverse waters, the salinity and temperature of feed water can vary significantly. Hence, the membranes must be versatile, adapting to these fluctuations while maintaining consistent water production to fulfill the rigorous demands of ocean-going vessels.
PSI MEMBRANE Pro-HR-SW seawater desalination membranes exhibit exceptional performance in desalination rate and steady water production. The water quality achieved by these membranes meets the stringent standards required by luxury cruise ships, ensuring reliability and excellence.
This impressive achievement led to the replacement of desalination membranes on three additional cruise ships. Proshare's triumph in this project marks it as the pioneering national brand securing international luxury cruise ship orders for desalination RO membranes.

Proshare Revolutionizing Water Filtration: Our Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our visionary team has ingeniously crafted a pioneering generation of reverse osmosis membranes utilizing state-of-the-art polymer interface nano-self-assembly technology. We have triumphantly surpassed the constraints of traditional methods through two pivotal advancements:
Revolutionary Ultra-Thin Separation Layer: Leveraging cutting-edge polymer interface nanotechnology, our team has masterfully minimized the separation layer's thickness to a remarkable dimension three times thinner than traditional polyamide thin films (previously constrained to 100 nm). This landmark enhancement significantly boosts water flux, leading to a dramatic surge in permeability.
Unparalleled Enhanced Performance: Introducing nanoparticles alongside specialized hydrophilic polymers has catalyzed unprecedented advancements in the membrane's hydrophilicity, anti-fouling capabilities, durability, and resistance to oxidation.
Setting a New Standard: Compared to traditional polyamide reverse osmosis membranes, Proshare's groundbreaking innovation showcases extraordinary breakthroughs in four essential aspects:
Innovative Self-Assembled Nanocomposite Films
Through the seamless integration of nano-scale precision control and nano-doping modification, we craft ultra-thin, meticulously ordered separation layers via advanced polymer interface nanotechnology. This method triumphs over the limitations of conventional polyamide membranes in achieving uniform thickness and material diversity.
Superior Enhanced Water Flux and Energy Efficiency
Optimizing the layer-by-layer self-assembly process allows us to precisely control the functional layer thickness, achieving an astounding 3x reduction compared to traditional membranes. This breakthrough delivers >3x amplified water flux coupled with an impressive 30% reduction in energy consumption.
Innovative Use of Novel Polymer Materials with Exceptional Chemical Stability
Venturing beyond polyamide, our team harnesses advanced hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These cutting-edge materials demonstrate outstanding oxidation resistance (enduring exposure to 10 ppm chlorine) and remarkable pH tolerance (stable across a pH range of 1-12).
Innovative Anti-Fouling Surface Engineering
