Successful Cases Reference
Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
Traditionally, the application of desalination membranes on international luxury cruise ships has been dominated by a select few prestigious international brands. With the cruise ship's trajectory, the quality of feed water, including its salinity and temperature, can vary significantly. Thus, the membranes must adeptly adapt to different conditions while consistently ensuring stable water production to fulfill the stringent demands of ocean-going vessels.
The PSI MEMBRANE Pro-HR-SW seawater desalination membranes have showcased exceptional performance in both desalination rates and the stability of water production. The water quality produced by these state-of-the-art membranes has successfully met the rigorous standards set by the cruise ships.
This outstanding achievement led to the replacement of desalination membranes on three additional cruise ships. Proshare's triumphant endeavor in this venture 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 Our team at Proshare has ingeniously developed a revolutionary new generation of reverse osmosis membranes, leveraging cutting-edge polymer interface nano-self-assembly technology. By harnessing two pivotal advancements, we have boldly overcome the traditional boundaries of reverse osmosis membrane development:
Ultra-Thin Separation Layer: Utilizing advanced polymer interface nanotechnology, our team has remarkably reduced the thickness of the separation layer to an astonishing threefold thinner than conventional polyamide thin films, which were previously constrained to 100 nm. This breakthrough dramatically enhances water flux, resulting in a profound improvement in permeability.
Enhanced Performance: With the innovative inclusion of nanoparticles and specialized hydrophilic polymers, we've achieved groundbreaking strides in the membrane's hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance-propelling membrane performance to new heights.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases remarkable breakthroughs in four pivotal areas:
Self-Assembled Nanocomposite Films
Through the precise integration of nano-scale precision control and nano-doping modification, we have crafted ultra-thin, highly ordered separation layers using pioneering polymer interface nanotechnology. This approach transcends the conventional limitations of polyamide membranes, achieving unparalleled thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
By meticulously fine-tuning the 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 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Surpassing polyamide, our team employs advanced hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These materials exhibit unparalleled oxidation resistance (withstanding up to 10 ppm chlorine exposure) and pH tolerance (maintaining stability across a 1-12 pH range).
Anti-Fouling Surface Engineering
Our state-of-the-art superhydrophilic surface, with a contact angle of less than 10°, combined with nanoparticle reinforcement, reduces the propensity for organic fouling by an impressive 50%. This extends chemical cleaning cycles from 3 months to 6 months and slashes maintenance costs by a remarkable 40%.
