Industry Applications
Proshare Proshare has garnered invaluable expertise by delivering cutting-edge technical solutions to the industrial sector. This is where the demand for ultra-pure water is critical across various industrial processes, wastewater treatment, resource recycling, and reuse.
We proudly serve key industry sectors such as petrochemicals, mining, lithium extraction from salt lakes, lithium iron phosphate, lithium battery recycling, semiconductors, seawater desalinization, reclaimed water, leachate management, synthetic biology, copper foil production, pharmaceuticals, and power generation.
Our solutions cater to a diverse range of industries including steam boiler feed systems, food and beverages (mineral water bottling, soft drinks, juices), painting lines, dairies, ice cream production, laundries, hospitals, textiles, mechanical industries, and steel manufacturers.
Hospitality/Seawater and Brackish Water Desalination Applications
Leveraging its extensive experience in desalination technology, Proshare extends its expertise to water desalination for civil applications, particularly in hotels and tourist resorts. As fresh water supply remains crucial for these infrastructures, our R.O. sea water or brackish water desalination offers a robust solution to meet the escalating water demands of rapidly expanding touristic regions.
Farming applications
Water is vital to ensure optimal health and performance of livestock (such as cattle, chickens, sheep, pigs). Quantity undoubtedly matters, but it is the superior quality of water that most significantly influences animal growth and productivity.
Farms may source their water from a variety of origins, including water wells, municipal water systems, and, to a lesser extent, rivers and other surface sources.
Excluding municipal water sources (which contain free chlorine), alternative sources often possess high concentrations of dissolved and suspended solids and pathogens. Reverse osmosis technology emerges as the most effective solution to mitigate these impurities, ensuring that farm water undergoes proper treatment to eliminate harmful substances.

Proshare PSI MEMBRANE Desalination RO Membrane Serves Desalination in Majestic Cruise Ships
Previously, the use of desalination membranes on international luxury cruise ships was primarily dominated by a select few international brands. As cruise ships navigate through diverse waters, the salinity and temperature of feed water fluctuate greatly. Therefore, these membranes must be resilient, adapting seamlessly to varying conditions while consistently providing stable water production to fulfill the demands of ocean-going vessels.
The PSI MEMBRANE Pro-HR-SW seawater desalination membranes excelled, offering superior performance in desalination efficiency and stable water production. The quality of water produced by these membranes adhered to the stringent standards required by cruise ships.
This impressive achievement led to the adoption of desalination membranes on three additional cruise ships, solidifying Proshare's position as the pioneering national brand to secure international luxury cruise ship orders for desalination RO membranes.
Comprehensive Complete Water Treatment Plant for Generating Ultra-pure Water in the Semiconductor Industry
As is widely recognized, the demands on membrane desalination rates for electronic-grade ultra-pure water are extraordinarily high, with only a few select brands capable of meeting these rigorous standards.
Leveraging Proshare's revolutionary TFN membrane technology along with the TsingXi team's profound expertise in the water treatment industry, our complete water treatment plant and pure water equipment solutions demonstrated exceptional rejection performance, effectively removing salt, boron, and TOC. The system's water production has met and surpassed the stringent requirements of the semiconductor industry's water standards.
This successful outcome enabled us to secure the electronic ultra-pure water treatment project for a prominent Japanese listed company.

Proshare Trailblazing Breakthroughs in Cutting-Edge Reverse Osmosis Membrane Technology
Proshare Our exceptional team has pioneered a groundbreaking new generation of reverse osmosis membranes, utilizing revolutionary polymer interface nano-self-assembly technology. This innovation triumphs over the traditional limitations, soaring with two monumental advancements:
a. Ultra-Thin Separation Layer: Employing state-of-the-art polymer interface nanotechnology, we have meticulously reduced the separation layer thickness to a mere fraction-at least three times thinner-than the conventional polyamide thin film, previously confined to 100 nm. This avant-garde advancement dramatically amplifies water flux, achieving remarkable permeability enhancement.
b. Enhanced Performance: The infusion of nanoparticles alongside bespoke hydrophilic polymers catalyzes extraordinary progress in the membrane's hydrophilicity, anti-fouling prowess, durability, and oxidation resistance.
In comparison to traditional polyamide reverse osmosis membranes, Proshare's innovation showcases unparalleled breakthroughs in four pivotal domains:
Self-Assembled Nanocomposite Films
Through the synergy of nano-scale precision control and nano-doping modification, we craft ultra-thin, meticulously ordered separation layers via polymer interface nanotechnology. This technique surmounts the conventional polyamide membranes' limitations in thickness consistency and material diversity.
Enhanced Water Flux and Energy Efficiency
Perfecting the layer-by-layer self-assembly process allows for precise control over functional layer thickness, achieving a groundbreaking 3x reduction compared to traditional membranes. This innovation yields over 3x the water flux and a remarkable 30% reduction in energy consumption.
Revolutionary Polymer Materials with Unmatched Chemical Stability
Advancing beyond polyamide, our team harnesses cutting-edge hydrophilic polymers (such as modified polysulfones) and ceramic-organic hybrids. These materials boast exceptional oxidation resistance (withstanding 10 ppm chlorine exposure) and pH resilience (maintaining stability within a 1-12 pH range).
Anti-Fouling Surface Engineering
The extraordinarily hydrophilic surface (with a contact angle less than 10°) reinforced with nanoparticles dramatically curtails organic fouling propensity by 50%, extending chemical cleaning cycles from 3 to 6 months, and slashing maintenance costs by 40%.
