China's first large-scale seawater desalination for the municipal pipe network starts in Tianjin on May 26, 2006

The Beijiang project, China's first large-scale seawater desalination for the municipal pipe network, started in Tianjin on May 26, 2006.

Built by State Development & Investment Corp., Ltd. (SDIC), the project was operated in a circular economy mode of "power generation - seawater desalination - salt production with concentrated seawater - land conservation - waste reuse".

To date, four 1000-megawatt ultra-supercritical coal-fired generating units and facilities that can desalinate 500,000 tons of seawater have been put into use, realizing graded energy consumption and making possible zero discharge of waste.

The raw materials of the seawater desalination are waste heat from a generating process and seawater. The main output products are desalinated water and concentrated seawater used to produce salt at Hangu Saltworks.
