Successful Cases Reference
Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
Historically dominated by a few international brands, the application of desalination membranes on international luxury cruise ships faces challenges due to fluctuating feed water quality, influenced by factors such as salinity and temperature during the ship's journey. Thus, the membranes must be highly adaptive, ensuring stable water production to meet the demanding requirements of ocean-going vessels.
PSI MEMBRANE Pro-HR-SW seawater desalination membranes deliver outstanding performance, excelling in both desalination rate and stable water production. The high-quality water produced seamlessly meets the stringent standards required by luxury cruise ships.
This remarkable performance led to the replacement of desalination membranes on an additional three cruise ships. Proshare proudly stands as the first national brand to secure international luxury cruise ship orders for desalination RO membranes, marking a significant milestone in the industry.

Proshare Team's Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our innovative Proshare team has crafted a revolutionary new generation of reverse osmosis membranes using cutting-edge polymer interface nano-self-assembly technology. This breakthrough surmounts the constraints of traditional membrane development through two pivotal advancements:
Ultra-Thin Separation Layer: Leveraging state-of-the-art polymer interface nanotechnology, we have achieved an astounding reduction in the separation layer's thickness-now at least three times thinner than conventional polyamide thin films (historically capped at 100 nm). This advancement skyrockets water flux, marking a significant leap in permeability and efficiency.
Enhanced Performance: By incorporating nanoparticles and specialized hydrophilic polymers, we've propelled the membrane's performance to new heights, showcasing remarkable improvements in hydrophilicity, anti-fouling capability, durability, and oxidation resistance. This ensures longevity and superior operational efficiency.
Compared to traditional polyamide reverse osmosis membranes, Proshare's innovation shines brightly with breakthroughs in four critical dimensions:
Self-Assembled Nanocomposite Films
Through the masterful integration of nano-scale precision control and nano-doping modification, we've developed ultra-thin, highly ordered separation layers via polymer interface nanotechnology. This sophisticated approach surpasses the limitations of conventional polyamide membranes in both thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Our meticulous optimization of the layer-by-layer self-assembly process ensures precise control over functional layer thickness, achieving an impressive 3x reduction compared to traditional membranes. This achievement delivers >3x higher water flux and 30% lower energy consumption-a testament to our commitment to sustainability and efficiency.
Novel Polymer Materials with Superior Chemical Stability
Breaking away from the confines of polyamide, our team employs advanced hydrophilic polymers, such as modified polysulfones, alongside ceramic-organic hybrids. These materials boast extraordinary oxidation resistance (withstanding 10 ppm chlorine exposure) and remarkable pH tolerance (stability across a 1-12 pH range), making them ideal for diverse applications.
Anti-Fouling Surface Engineering
Our superhydrophilic surface, with a contact angle of less than 10°, combined with nanoparticle reinforcement, dramatically slashes organic fouling propensity by 50%. This extension of chemical cleaning cycles from 3 months to 6 months not only enhances operational efficiency but also slashes maintenance costs by a remarkable 40%.
