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 select few international brands. The quality of feed water, such as salinity and temperature, fluctuates with the cruise ship's journey. Therefore, the membranes must seamlessly adapt to varying conditions while ensuring consistent and stable water production to meet the demands of these ocean-going vessels.
PSI MEMBRANE Pro-HR-SW seawater desalination membranes have demonstrated superior performance in both desalination rate and stable water production. The water quality produced by these membranes not only meets but exceeds the stringent requirements of luxury cruise ships.
This remarkable achievement led to the replacement of desalination membranes on three additional luxury cruise ships. Proshare's success in this venture establishes it as the first national brand to secure international luxury cruise ship orders for desalination RO membranes.
A Complete Water Treatment Plant for Generating Ultra-pure Water in the Semiconductor Industry

Proshare A Revolutionary Leap in Reverse Osmosis Membrane Technology by Our Exceptional Team
Proshare Our dedicated team has pioneered a groundbreaking new generation of reverse osmosis membranes. Utilizing cutting-edge polymer interface nano-self-assembly technology, we've surmounted the traditional barriers of reverse osmosis membrane development through two transformative advancements:
Ultra-Thin Separation Layer: Harnessing the power of polymer interface nanotechnology, our team has remarkably minimized the separation layer's thickness to an impressive fraction-at least three times thinner than traditional polyamide thin films, which were previously restricted to 100 nm. This exceptional breakthrough amplifies water flux, remarkably enhancing permeability.
Enhanced Performance: By integrating nanoparticles with advanced hydrophilic polymers, we have achieved unprecedented strides in augmenting the membrane's hydrophilicity, anti-fouling properties, durability, and oxidation resistance.
In contrast to conventional polyamide reverse osmosis membranes, Proshare's innovative approach showcases breakthroughs in four critical domains:
Self-Assembled Nanocomposite Films
Through the fusion of nano-scale precision control and nano-doping modification, we construct ultra-thin, exquisitely ordered separation layers using polymer interface nanotechnology. This innovative technique surpasses the limitations of conventional polyamide membranes in terms of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By meticulously optimizing the layer-by-layer self-assembly process, we control the functional layer thickness with precision, achieving a remarkable 3x reduction compared to traditional membranes. This results in >3x higher water flux and a notable 30% reduction in energy consumption.
Novel Polymer Materials with Unmatched Chemical Stability
Our advancements transcend polyamide, as we leverage advanced hydrophilic polymers such as modified polysulfones and ceramic-organic hybrids. These materials boast remarkable oxidation resistance (withstanding up to 10 ppm chlorine exposure) and pH tolerance (remaining stable within a 1-12 pH range).
Anti-Fouling Surface Engineering
The superhydrophilic surface, with a contact angle of less than 10°, combined with nanoparticle reinforcement, significantly reduces the tendency for organic fouling by 50%, thereby extending chemical cleaning cycles from 3 to 6 months and slashing maintenance costs by 40%
