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 dominated by a select few international brands. These membranes must adapt to ever-changing conditions such as variations in feed water quality, salinity, and temperature during the ship's journey, while consistently ensuring stable and high-quality water production to meet the demanding needs of ocean-going vessels.
The PSI MEMBRANE Pro-HR-SW seawater desalination membranes have showcased their exceptional prowess, delivering outstanding performance in both desalination rates and stable water production. These membranes consistently produce water that meets the exacting standards required by luxury cruise ships.
The remarkable achievements with these membranes led to their adoption on three additional luxury cruise ships. Proshare's success in this prestigious market has established it as the first national brand to secure international orders for desalination RO membranes on luxury cruise ships, marking a significant milestone.
A Comprehensive Water Treatment Plant for Ultra-pure Water Generation in the Semiconductor Sector
It is well understood that the requirements for electronic-grade ultra-pure water desalination rates are exceptionally stringent, and only a select few brands are capable of meeting these high standards.
Leveraging Proshare's groundbreaking TFN membrane technology and the TsingXi team's extensive expertise in the water treatment industry, a complete water treatment plant solution for pure water equipment demonstrated outstanding rejection performance for salt, boron, and TOC. The system's water production capabilities fully satisfy the stringent requirements of the semiconductor industry's production water standards.
This successful outcome secured Proshare a prestigious contract for an electronic ultra-pure water treatment project with a prominent Japanese listed company.

Proshare Pioneering Breakthroughs in Next-Gen Reverse Osmosis Membrane Technology
Proshare Our expert team at Proshare has creatively pioneered a groundbreaking new generation of reverse osmosis membranes, leveraging cutting-edge polymer interface nano-self-assembly technology. This has allowed us to transcend the conventional constraints associated with traditional reverse osmosis membrane development, thanks to two revolutionary advancements:
Ultra-Thin Separation Layer: Utilizing advanced polymer interface nanotechnology, our team has remarkably minimized the separation layer's thickness to be at least three times thinner than the conventional polyamide thin film, which was previously limited to 100 nm. This landmark achievement significantly boosts water flux, resulting in a dramatic enhancement in permeability.
Outstanding Performance Enhancements: The strategic incorporation of nanoparticles and specialized hydrophilic polymers has catalyzed revolutionary improvements in the membrane's hydrophilicity, anti-fouling capabilities, durability, and oxidation resilience.
In comparison to standard polyamide reverse osmosis membranes, Proshare's innovative design manifests substantial breakthroughs across four pivotal dimensions:
Self-Assembled Nanocomposite Films
Through the amalgamation of nano-scale precision control and nano-doping modification, we create ultra-thin, highly ordered separation layers using polymer interface nanotechnology. This revolutionary methodology addresses the traditional limitations of polyamide membranes regarding thickness uniformity and material diversity.
Amplified Water Flux and Enhanced Energy Efficiency
Our meticulous optimization of the layer-by-layer self-assembly process ensures precise control over functional layer thickness, achieving a remarkable 3x reduction compared to conventional membranes. This advancement culminates in over 3x greater water flux and a 30% reduction in energy consumption.
Innovative Polymer Materials with Exceptional Chemical Stability
Surpassing the limitations of polyamide, our team employs advanced hydrophilic polymers, such as modified polysulfones, and ceramic-organic hybrids. These materials offer unparalleled oxidation resistance (withstanding 10 ppm chlorine exposure) and pH adaptability (maintaining stability across a pH range of 1-12).
Advanced Anti-Fouling Surface Engineering
By combining a superhydrophilic surface (contact angle <10°) with nanoparticle reinforcement, we effectively reduce the organic fouling propensity by 50%. Consequently, chemical cleaning cycles are extended from three months to six months, leading to a 40% reduction in maintenance costs.
Our commitment to excellence is highlighted by our prestigious certifications, which include the Health & Safety Management System Certificate, the Environmental Management System Certificate, and the ISO 9001 Quality System Certificate-each a testament to our dedication to quality and sustainable practices.
