Successful Cases Reference
Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
Historically, the application of desalination membranes on international luxury cruise ships has been the domain of a few prominent international brands. The challenge lies in the fluctuating quality of feed water, influenced by salinity and temperature changes during the cruise ship's journey. Hence, the membranes must be versatile, adapting to varying conditions while ensuring consistent and reliable water production to meet the comprehensive needs of these ocean-going vessels.
PSI MEMBRANE Pro-HR-SW seawater desalination membranes have excelled in both desalination rate and stable water production, exceeding expectations. The water quality generated by these membranes meets and surpasses the stringent standards required by luxury cruise ships.
This exceptional success resulted in the replacement of desalination membranes on three additional cruise ships. Proshare's triumph in this venture marks it as the first national brand to secure orders for desalination RO membranes from international luxury cruise ships.

Proshare Pioneering Leap in Revolutionary Reverse Osmosis Membrane Technology
Proshare has astutely forged ahead with the innovative development of a groundbreaking generation of reverse osmosis membranes, expertly utilizing polymer interface nano-self-assembly technology. This advancement triumphantly transcends the traditional limitations of reverse osmosis membrane development, marked by two pivotal breakthroughs:
Ultra-Thin Separation Layer Mastery: Harnessing the power of polymer interface nanotechnology, our team has ingeniously minimized the thickness of the separation layer to an unprecedented threefold reduction compared to conventional polyamide thin films (traditionally limited to 100 nm). This monumental advancement dramatically boosts water flux, resulting in a remarkable enhancement in permeability.
Optimized Performance Advancement: The strategic integration of nanoparticles coupled with specialized hydrophilic polymers has revolutionized the membrane's hydrophilicity, anti-fouling capabilities, durability, and oxidation resistance, setting new standards in membrane performance.
When placed alongside traditional polyamide reverse osmosis membranes, Proshare's cutting-edge innovation showcases breakthroughs across four crucial dimensions:
Self-Assembled Nanocomposite Films Precision
By leveraging nano-scale precision control and nano-doping modification, ultra-thin and highly ordered separation layers are meticulously created through polymer interface nanotechnology. This ingenious method resolves the challenges of conventional polyamide membranes in achieving consistent thickness and diverse material composition.
Enhanced Water Flux and Energy Efficiency Mastery
Through the meticulous optimization of the layer-by-layer self-assembly technique, functional layer thickness is precisely fine-tuned, achieving a remarkable threefold reduction in comparison to traditional membranes. This leads to an impressive >3x increase in water flux while also realizing a notable 30% decrease in energy consumption.
Novel Polymer Materials for Unmatched Chemical Stability
Departing from polyamide, our team employs cutting-edge hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These innovative materials demonstrate unparalleled oxidation resistance (capable of withstanding up to 10 ppm chlorine exposure) and exceptional pH tolerance (maintaining stability within a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
