SEA WATER DESALINATION
Application of our company's "double membrane process" to deeply treat seawater in a seawater desalination plant
Project introduction
A seawater desalination plant uses "double membrane process" to deeply treat seawater. Water production is supplied for city tap water. In recent years, the factory has been using imported film products. At present, the plant has one of the largest municipal drinking water project in China, with a daily treatment capacity of 100,000 tons. After desalination, the sea water enters people's homes through the municipal pipe network.
The process flow
The on-site technological process is shown in the following figure.
