Industry Applications
Proshare Proshare Innovation Suzhou Co., Ltd. has garnered a wealth of experience by delivering cutting-edge technical solutions to the industrial sector, where the demand for impeccably pure water is paramount across a variety of industrial processes, including wastewater treatment, resource recycling, and more.
Our expertise spans across vital industry sectors such as petrochemical, mining, lithium extraction from salt lakes, lithium iron phosphate & lithium battery recycling, semiconductors, seawater desalination, reclaimed water processing, leachate management, synthetic biology, copper foil production, pharmaceuticals, and power generation.
Additionally, we cater to diverse fields including steam boiler water supply, food & beverages (encompassing mineral water bottling, soft drinks, and juices), painting lines, dairy production, ice cream manufacturing, laundries, hospitals, textile production, mechanical industries, steel companies, and more.
Hospitality/Seawater and Brackish Water Desalination Applications
Proshare's extensive experience in desalination technology is also harnessed for water desalination projects catering to civil use in hotels and tourist resorts. Freshwater availability is crucial for these infrastructures, and R.O. seawater or brackish water desalination represents an alternative solution capable of fulfilling the required capacities of rapidly expanding tourist areas with increasing water demands.
Farming applications
Water is indispensable for ensuring the vitality and peak performance of farm animals such as cattle, chickens, sheep, and pigs. Beyond mere quantity, the water's quality plays a pivotal role in influencing the desired growth of these animals.
Farm water sources vary widely, including water wells, civil water networks, and to a lesser extent, rivers and other surface sources. Each source brings unique challenges that must be addressed to ensure optimal water quality.
With the exception of water from civil networks (which contain free chlorine), other sources often harbor high concentrations of dissolved and suspended solids, as well as pathogens. Reverse osmosis technology has proven to be the most effective method for mitigating these negative impacts, necessitating that contaminated farm water undergo technological treatment to reduce any harmful substances that may affect the animals.
Municipal and Civil use
We deliver innovative, scalable solutions for the efficient and sustainable treatment of wastewater and effluents, with a broad portfolio of patented technologies. Our collaboration with national-level experts and research institutions ensures peace of mind for municipalities bound by stringent health and environmental standards, while our commitment to ongoing improvement is driven by systematic engineer feedback from the field.

Successful Cases Reference
Unveiling the Power of Proshare PSI MEMBRANE Advanced Desalination RO Membrane Solutions Serves Desalination Pioneeringly In Luxurious Cruise Ship Ventures
The deployment of desalination membranes on international luxury cruise ships has traditionally been led by a limited number of global brands. Journeying through diverse waters, these ships experience varying quality of feed water, such as differing salinity and temperature. As a result, the membranes are required to adapt to these conditions, maintaining consistent water production to satisfy the demands of ocean-going vessels.
The PSI MEMBRANE Pro-HR-SW seawater desalination membranes excelled in both desalination efficiency and water production stability. The quality of water produced by these membranes adhered to the stringent criteria set by the cruise ship industry.
These outstanding results paved the way for the replacement of desalination membranes on three additional cruise ships. Proshare's triumph in this domain marks it as the inaugural national brand to secure international luxury cruise ship orders for desalination RO membranes.
