Membrane Water Supply

The integrated technology with separation membrane as the core is used to replace the coarser treatment processes such as traditional precipitation, filtration, and ozone-activated carbon. This technology can remove 100% of the algae, microorganisms, bacteria, and E. coli in the municipal water supply, greatly reducing the amount of fungicides, and ensuring the safety of drinking water. This technology has stable effluent quality and is not affected by fluctuations in raw water quality. The process flow is short, the area is small (reduced by ½-⅓ compared to the traditional process); the service life is long, and the water production rate is high. This is the development direction of municipal water supply management.

Ⅰ. Salt water filter system of a fiber company in Nanjing

Project Introduction: The production capacity of the desalinated water system of this project is 240m3/h. The raw water of the desalinated water system adopts the filtered water after mixing the Yangtze River and Chu River, and adopts the process of "dual media filter + activated carbon filter + primary reverse osmosis + mixed bed" to realize the salt water filter.

Project location: Nanjing, Jiangsu province; processing scale: 240 m3/h; process used: dual media + activated carbon + first-level reverse osmosis + mixed bed; influent water quality: surface water; effluent water quality: meet GB-T1576-2008 water quality requirements; operating status: normal operation.

Ⅲ. Boiler make-up water project using membrane filtration technique for a company in Hebei province

Project introduction: Jiuwu Hi-tech cooperated with a company in Hebei in 2018. The membrane filtration technique is used to treat raw water, and the produced water is applied to boiler make-up water and production process water of power plants. The characteristics of membrane water treatment process include advanced technology, high automation, easy operation and maintenance, stable water quality, low operation cost and small footprint, which can create more economic value for enterprises and society.
