Proshare PSI MEMBRANE Desalination RO Membrane Caters to Desalination Needs in Luxury Cruise Ships
Historically, international luxury cruise ships have relied heavily on a select few global brands for their desalination membrane needs. The dynamic nature of feed water quality, influenced by varying salinity and temperatures during voyages, demands adaptable membranes. These membranes must maintain consistent water production to meet the rigorous demands of oceanic travel.
Proshare's PSI MEMBRANE Pro-HR-SW seawater desalination membranes excelled in delivering exceptional desalination efficiency and steady water production. The resulting water quality surpassed the stringent standards expected by luxury cruise ships.
This outstanding achievement catalyzed the replacement of desalination membranes on three additional luxury cruise liners. Proshare's triumph marks a significant milestone as it becomes the premier national brand to secure international orders for desalination RO membranes aboard luxury cruise ships.

Proshare Team's Pioneering Breakthrough in Cutting-Edge Next-Generation Reverse Osmosis Membrane Technology
Proshare team has ingeniously crafted a revolutionary new generation of reverse osmosis membranes using advanced polymer interface nano-self-assembly technology, triumphing over the constraints of traditional reverse osmosis membrane development through two groundbreaking advancements:
Ultra-Thin Separation Layer: By harnessing the power of polymer interface nanotechnology, our team has remarkably reduced the thickness of the separation layer to at least three times thinner than the conventional polyamide thin film, which was previously capped at 100 nm. This pioneering development significantly enhances water flux, leading to a noteworthy improvement in permeability.
Enhanced Performance: By incorporating nanoparticles and specially engineered hydrophilic polymers, we've achieved unprecedented advancements in the membrane's hydrophilicity, anti-fouling capability, durability, and oxidation resistance
Compared to conventional polyamide reverse osmosis membranes, Proshare's groundbreaking innovation showcases breakthroughs in four essential aspects:
Self-Assembled Nanocomposite Films
The fusion of nano-scale precision control with nano-doping modification facilitates the creation of ultra-thin, highly ordered separation layers via advanced polymer interface nanotechnology. This method surmounts the constraints of traditional polyamide membranes concerning thickness consistency and material versatility.
Enhanced Water Flux and Energy Efficiency
By refining the layer-by-layer self-assembly process, the thickness of the functional layer is meticulously controlled, achieving a 3x reduction in comparison to traditional membranes. This advancement results in over 3x higher water flux and a remarkable 30% reduction in energy consumption.
Innovative Polymer Materials with Superior Chemical Stability
Moving beyond simple polyamide, our team employs cutting-edge hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These advanced materials exhibit outstanding resistance to oxidation (withstanding exposure to 10 ppm chlorine) and pH resilience (remaining stable across a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
The superhydrophilic surface (boasting a contact angle of less than 10°), reinforced with nanoparticles, dramatically reduces the propensity for organic fouling by 50%, extending chemical cleaning cycles from 3 months to 6 months and reducing maintenance costs by an impressive 40%
