Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Cruise Ship
Historically, the application of desalination membranes on international luxury cruise ships has been dominated by a select few major international brands. With the journey of a cruise ship, the quality of feed water, including factors like salinity and temperature, can vary significantly. To meet the demands of ocean-going vessels, it is crucial that membranes effectively adapt to these varying conditions while consistently providing stable water production.
The PSI MEMBRANE Pro-HR-SW seawater desalination membranes have exhibited outstanding performance in both desalination rate and the reliable production of water. These membranes produce water quality that meets the stringent standards required for cruise ships.
This exceptional outcome led to the replacement of desalination membranes on three more cruise ships. Proshare's triumph in this venture marks a significant achievement, establishing it as the first 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 innovative team at Proshare has masterfully created a revolutionary generation of reverse osmosis membranes utilizing advanced polymer interface nano-self-assembly technology. This cutting-edge technology triumphs over the constraints of traditional membrane development through two pivotal advancements:
Ultra-Thin Separation Layer: By harnessing state-of-the-art polymer interface nanotechnology, our team has adeptly minimized the separation layer's thickness to an astonishing threefold reduction compared to conventional polyamide films, which were previously constrained to a thickness of 100 nm. This monumental achievement significantly boosts water flux, leading to remarkable improvements in permeability.
Enhanced Performance: By integrating nanoparticles along with specialized hydrophilic polymers, groundbreaking strides have been made in the membrane's hydrophilicity, anti-fouling capability, enduring durability, and unmatched oxidation resistance.
Compared to traditional polyamide reverse osmosis membranes, Proshare's pioneering innovation marks substantial breakthroughs in four critical areas:
Self-Assembled Nanocomposite Films
With the fusion of nano-scale precision control and nano-doping modifications, creation of ultra-thin, highly organized separation layers through polymer interface nanotechnology is achieved. This method surpasses the limitations previously faced by conventional polyamide membranes regarding thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through meticulous optimization of the layer-by-layer self-assembly process, the functional layer's thickness is expertly controlled, resulting in a threefold reduction in thickness compared to traditional membranes. This meticulous control culminates in >3x higher water flux and 30% lower energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Surpassing the limitations of polyamide, our team employs cutting-edge hydrophilic polymers, such as modified polysulfones, alongside ceramic-organic hybrids. These advanced materials offer extraordinary oxidation resistance (withstanding 10 ppm chlorine exposure) and pH tolerance (maintaining stability across a pH range of 1-12).
Anti-Fouling Surface Engineering
The superhydrophilic surface, with a contact angle of less than 10°, combined with nanoparticle reinforcement, drastically reduces the propensity for organic fouling by 50%. This innovation extends chemical cleaning cycles from 3 months to an impressive 6 months, while reducing maintenance costs by a significant 40%
