Spain-based technology solutions provider for the energy and environment sectors, Abengoa, has commenced commercial operations at the Qingdao desalination plant in China.
The desalination plant, constructed at a cost of €135m, will use reverse osmosis technology to produce 100,000m³/day of drinking water from seawater to meet the drinking water demands of 7.5 million residents of Qingdao City.
Abengoa will be responsible for maintenance and operations of the plant for a period of 25 years, during which revenue generation from water sales is expected to be over €750m, and will further rise to €25m from technical support operations.
The reverse osmosis technology is used in the desalination plant's pre-treatment stage (ultra-filtration membranes) and in the centralised pumping system.
The Qingdao desalination plant will be energy efficient and can operate at extreme temperatures to produce remineralising desalinated water, which will have the lowest levels of turbidity.
Abengoa began construction of the plant in 2010, while the first desalination project was conducted using a project finance structure totally financed by local Chinese banks.
With the project, Abengoa's installed water desalination capacity will increase to nearly 1.1 million cubic metres per day.
The company has already developed desalination plants in Algeria, Ghana, India, and Spain.
