Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
For years, the realm of international luxury cruise ships has been predominantly controlled by a select few international brands, particularly in the application of desalination membranes. These vessels traverse diverse waters where feed water quality varies, influenced by changes in salinity and temperature. Thus, it is paramount for membranes to dynamically adapt to these shifting environments while steadfastly maintaining consistent water production to satisfy the rigorous demands of maritime travel.
The PSI MEMBRANE Pro-HR-SW seawater desalination membranes have set a new benchmark in performance, showcasing exceptional desalination rates along with unyielding water production stability. Not only did the water quality from these membranes align with the stringent criteria of luxury cruise ships, but it also surpassed expectations.
This outstanding achievement catalyzed the replacement of desalination membranes in three more cruise ships. Proshare's unprecedented success marks a historic milestone as the first national brand to secure international luxury cruise ship orders for desalination RO membranes.

Proshare: Pioneers in Water Purification Technology Team's Revolutionary Leap in the Future of Reverse Osmosis Membrane Technology
Proshare: Leading the Charge in Technological Advancement Our brilliant team has ingeniously developed a groundbreaking generation of reverse osmosis membranes utilizing cutting-edge polymer interface nano-self-assembly technology. This innovative approach triumphs over the barriers faced by traditional membrane development through two monumental breakthroughs:
Ultra-Thin Separation Layer: A Marvel of Modern Technology: By harnessing the power of polymer interface nanotechnology, our team has achieved a remarkable reduction in the separation layer's thickness, making it at least three times thinner than the conventional polyamide thin film (previously constrained to 100 nm). This astounding advancement dramatically boosts water flux, leading to a significant enhancement in permeability.
Enhanced Membrane Performance: Redefining Excellence: The meticulous incorporation of nanoparticles alongside specialized hydrophilic polymers has catalyzed groundbreaking improvements in the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance.
When compared to traditional polyamide reverse osmosis membranes, Proshare's pioneering innovation showcases breakthroughs across four pivotal dimensions:
Self-Assembled Nanocomposite Films: A New Era of Precision
Through the seamless integration of nano-scale precision control and nano-doping modification, we craft ultra-thin, meticulously ordered separation layers via polymer interface nanotechnology. This ingenious strategy overcomes the traditional polyamide membranes' limitations in thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency: Achieving Sustainability
By optimizing the sophisticated layer-by-layer self-assembly process, we precisely control the functional layer thickness, achieving an impressive 3x reduction compared to traditional membranes. This results in >3x higher water flux and, an incredible 30% lower energy consumption.
Revolutionary Polymer Materials with Unmatched Chemical Stability
Beyond polyamide, our team ingeniously employs advanced hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids, which exhibit extraordinary oxidation resistance (withstanding 10 ppm chlorine exposure) and, impressive pH tolerance (ensuring stability across a 1-12 pH range).
Innovative Anti-Fouling Surface Engineering: Extending Lifespan
Our superhydrophilic surface (boasting a contact angle <10°) fortified with nanoparticle reinforcement significantly diminishes organic fouling propensity by 50%, doubling chemical cleaning cycles from 3 to 6 months and slashing maintenance costs by a remarkable 40%.
