Proshare PSI MEMBRANE Desalination RO Membrane Empowering Desalination in Luxury Cruise Industry
Historically, the realm of desalination membranes for international luxury cruise ships has been dominated by a select few international brands. These membranes must navigate the challenges of fluctuating feed water quality-such as salinity and temperature-throughout the cruise ship's journey. Thus, they must exhibit adaptability to diverse conditions while ensuring consistent, high-quality water production to satisfy the rigorous demands of ocean-going vessels.
The PSI MEMBRANE Pro-HR-SW seawater desalination membranes stand out with their exceptional desalination rate and consistently stable water production. The water quality produced by Proshare's membranes meets and exceeds the stringent requirements set by luxury cruise liners.
This extraordinary achievement led to the replacement of desalination membranes on three additional cruise ships. Proshare has solidified its position as the pioneering national brand to secure international luxury cruise ship orders for desalination RO membranes.

Proshare Our Team's Revolutionary Breakthrough in Next-Generation Reverse Osmosis Membrane Technology
Proshare Our pioneering team has crafted an innovative generation of reverse osmosis membranes, harnessing the power of polymer interface nano-self-assembly technology. We have triumphantly surpassed the traditional bounds of reverse osmosis membrane development through two groundbreaking advancements:
Ultra-Thin Separation Layer: Through the adept use of polymer interface nanotechnology, our team has achieved a remarkable reduction in the separation layer's thickness, making it at least three times thinner than the conventional polyamide thin film, which was previously constrained to 100 nm. This paradigm-shifting breakthrough dramatically boosts water flux, delivering a remarkable escalation in permeability.
Enhanced Performance: By incorporating nanoparticles along with specialized hydrophilic polymers, we have ushered in transformative advancements in the membrane's hydrophilicity, anti-fouling capabilities, durability, and resilience against oxidation.
In stark contrast to the traditional polyamide reverse osmosis membranes, Prosharehas accomplished innovations that manifest breakthroughs in four pivotal domains:
Self-Assembled Nanocomposite Films
With the fusion of nano-scale precision control and nano-doping modification, we craft ultra-thin, exquisitely ordered separation layers through polymer interface nanotechnology. This ingenious approach triumphs over the limitations of conventional polyamide membranes, addressing issues of thickness uniformity and material diversity.
Enhanced Water Flux and Energy Efficiency
Through refining the layer-by-layer self-assembly process, the functional layer's thickness is meticulously controlled, achieving a remarkable 3x reduction compared to traditional membranes. This advancement results in over 3x higher water flux and a 30% reduction in energy consumption.
Novel Polymer Materials with Superior Chemical Stability
Advancing beyond polyamide, our team employs cutting-edge hydrophilic polymers like modified polysulfones and ceramic-organic hybrids. These avant-garde materials exhibit extraordinary resistance to oxidation (withstanding up to 10 ppm chlorine exposure) and pH tolerance (maintaining stability across a 1-12 pH range).
Anti-Fouling Surface Engineering
The superhydrophilic surface, characterized by a contact angle of less than 10°, fortified with nanoparticle reinforcement, curtails organic fouling tendencies by 50%. This innovation extends chemical cleaning cycles from 3 months to an impressive 6 months, resulting in a 40% reduction in maintenance costs.
Our unwavering commitment to excellence is exemplified by our prestigious certifications: Health & Safety Management System Certificate, Environmental Management System Certificate, and the distinguished ISO 9001 Quality System Certificate. Each of these accolades stands as a testament to Proshare Innovation Suzhou Co., Ltd.'s dedication to maintaining top-tier standards across every facet of our operations.
