Tianjin Dagang, China

What is it?

A 100,000m³/d seawater reverse osmosis plant in Dagang that has been supplying industrial grade and potable water to Tianjin Province since August 2009.

Who is responsible?

Hyflux developed the plant on a BOO basis, utilising energy recovery technology supplied by Energy Recovery Inc. The off-taker is the Tianjin Dagang District Government.

What makes it special?

• Tianjin Dagang is the largest RO seawater desalination plant in China and the first major project delivered by a foreign private developer in the country.

• The project includes a number of neat engineering solutions, such as the use of power station cooling water to increase the feedwater temperature. This enables a minimum intake structure, and increases operating efficiency even in the icy Tianjin winter.

• Dagang has the largest UF seawater pretreatment system currently in use anywhere in the world.
