Proshare Proshare has garnered invaluable expertise by delivering cutting-edge technical solutions to the industrial sector. Our focus is on environments where ultra-pure water is a non-negotiable necessity for diverse industrial processes, including wastewater treatment and reuse, alongside resource recycling.
Proshare is deeply invested in pivotal industry sectors. Our reach spans petrochemicals, mining, lithium extraction from salt lakes, lithium iron phosphate, and lithium battery recycling. We also specialize in semiconductors, seawater desalination, reclaimed water, leachate management, synthetic biology, copper foil production, pharmaceuticals, and power generation.
Our diverse expertise extends to critical applications such as steam boiler feeding, the food and beverage industry (including mineral water bottling, soft drinks, and juices), painting lines, dairy production, ice cream manufacturing, laundries, hospitals, textiles, mechanical industries, and steel companies.
Hospitality/Seawater and Brackish Water Desalination Applications
Proshare's extensive experience in desalination technology is adeptly utilized in providing water desalination solutions for civil uses, such as hotels and tourist resorts. Fresh water supply is crucial for these establishments, and our R.O. sea or brackish water desalination offers a robust alternative that meets the growing water capacity demands of burgeoning tourist destinations.
Farming Applications
Water is indispensable for ensuring optimal health and performance in livestock such as cattle, chickens, sheep, and pigs. It is not just the volume of water that affects animal growth but critically, its quality too.
Farm water may originate from various sources including water wells, municipal water networks, and to a lesser degree, rivers and other surface sources.
Excluding municipal water networks (which contain free chlorine), other sources tend to have high levels of dissolved and suspended solids and pathogens. Reverse osmosis technology emerges as the most effective method to counter these impurities, ensuring that farm-used water undergoes necessary treatment to mitigate harmful substances and safeguard animal well-being.

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 brands. These membranes must adeptly handle varying feed water quality due to fluctuations in salinity and temperature as the ships journey across different waters. It is essential for these membranes to adapt seamlessly to ensure consistent and stable water production, catering perfectly to the demanding needs of ocean-going vessels.
PSI MEMBRANE Pro-HR-SW seawater desalination membranes showcased exceptional performance, excelling in both desalination rate and maintaining stable water production. The quality of water produced by these innovative membranes surpassed the rigorous standards required by cruise ships.
Thanks to this outstanding achievement, desalination membranes were replaced on three additional cruise ships. Proshare's triumph in this endeavor heralds it as the pioneering national brand to secure international luxury cruise ship orders for desalination RO membranes.
A Complete Water Treatment Plant for Generating Ultra-pure Water in the Semiconductor Industry
It is well-known that electronic-grade ultra-pure water demands extraordinarily high desalination rates. Only a handful of brands can meet these stringent requirements.
Thanks to Proshare's revolutionary TFN membrane technology and the TsingXi team's extensive experience in water treatment, the complete water treatment plant and pure water equipment solutions exhibited excellent rejection performance for salt, boron, and TOC. The system's water production successfully met the demanding standards of the semiconductor industry.
This positive outcome paved the way for us to secure the electronic ultra-pure water treatment project with a prestigious Japanese listed company.
Proshare Tailor made TFN special acid-resistant and high-pressure membranes for Wastewater Treatment in Petrochemical / Refining Truly Achieve Zero Liquid Discharge
ProshareTailor made TFN special acid-resistant and high-pressure membranes separation and concentration devices for wastewater treatment containing ammonium sulphate desulphurisation. These devices achieved wastewater concentration up to 40 times, with an ammonium sulphate concentration of ≥ 20% in the concentrated water. This dramatically reduced the energy consumption required for subsequent evaporation and crystallisation, resulting in substantial cost savings for the user. The stable water quality met the corporate standard Q/SH 0628.2-2014 for circulating water make-up water for China Petroleum and Chemical Corporation. Zero wastewater discharge has been truly achieved.
This outstanding result led to subsequent orders from other subsidiaries of the group.
This membrane is also applicable to other high-temperature, highly acidic wastewater scenarios containing ammonium sulphate. Industries such as energy, refining, chemical, and metallurgical benefit from this technology. The latest advancements in ammonia desulphurisation technology, combined with carbon capture, support new energy consumption and the development of a green industry chain, aligning perfectly with the national 'dual-carbon policy'.
