Industry Applications
Proshare Proshare Innovation Suzhou Co., Ltd. has honed its extensive expertise through offering cutting-edge technical solutions to various industrial sectors. These sectors require ultra-pure water for critical industrial procedures, wastewater treatment, and resource recycling.
Our engagements span numerous primary industry sectors: petrochemical, mining, lithium extraction from salt lakes, lithium iron phosphate and lithium battery recycling, semiconductor, seawater desalination, leachate, reclaimed water, synthetic biology, copper foil, pharmaceuticals, and power industries.
We also cater to diverse applications like steam boiler feed, food and beverage industries (mineral water bottling, soft drinks, juices), painting lines, dairies, ice cream production, laundries, hospitals, textiles, mechanical industries, and steel manufacturing companies.
Hospitality/Seawater and Brackish Water Desalination Applications
Leveraging Proshare's extensive expertise in desalination technology, we extend our solutions to water desalination for civil use in hotels and touristic resorts. Ensuring fresh water supply is crucial for these infrastructures. Our reverse osmosis technology for seawater and brackish water desalination provides a reliable alternative, meeting the increasing water demands of rapidly developing tourism areas.
Farming applications
In the realm of farming, water quality and availability are paramount for ensuring the health and optimal productivity of livestock such as cattle, chickens, sheep, and pigs. The growth and performance of these animals are influenced not only by water quantity but significantly by the water's purity.
Farm water can originate from various sources including water wells, municipal networks, and, to a lesser extent, rivers and surface sources. However, these sources often contain high levels of dissolved solids and pathogens, necessitating advanced treatment.
Excluding water from municipal networks, which contains free chlorine, other sources usually have high concentrations of dissolved and suspended solids and pathogens. Reverse osmosis technology is the most effective method to mitigate the adverse effects of contaminants in farm water, ensuring harmful substances are reduced to safe levels for animal welfare.
Municipal and Civil Use
We deliver forward-thinking and scalable solutions for the efficient and sustainable treatment of wastewater and effluents. Our comprehensive suite of patented technologies, backed by national-level experts and scientific partnerships, ensures compliance with stringent health and environmental standards for municipalities.
