Tianjin SDIC Project - China’s Largest Desalination Plant case study

China’s SDIC (State Development and Investment Corporation) needed a reliable and sustainable supply of clean water near the Tianjin power plant, 200km northeast of Beijing. The plant provides high quality drinking water for the local population, as well as industrial boiler make up and process water for the power plant.

IDE’s Multi-Effect Distillation solution is a win-win concept. The Tianjin Beijing Power Plant is a mega-size engineering system composed of a power plant, seawater desalination plant and salt production from brine, and is managed as an integrated system in which all three parts are interdependent on one another.


  • Capacity: 200,000 m3/day
  • Technology: Multi-Effect Distillation (MED)
  • Project Type: Engineering-Procurement-Construction (EPC)
  • Location: Hangu, Tianjin, China
  • Footprint: 125m x 160m
  • Commission date: 2010, 2013


Reduced atmospheric heat discharge - the system is powered by waste heat generated by the Tianjin SDIC electricity plant, thereby reducing costs and minimizing the discharge of heat from the plant to the atmosphere

Table salt production - using a new technology, the system recycles post-desalination waste brine to evaporation ponds for production of pure table salt

Reduced environmental impact - a unique closed seawater circulation technology eliminates dependence on external water resources

Trusted long-term partnership - after the successful installation of the first 4 units, SDIC selected IDE to expand the desalination plant and reach a total capacity of 200,000 m3/day
