Siemens Completes Desalination R&D Project

Siemens has entered the next phase of a project to bring its low-energy seawater desalination technology to market.

The company completed the research and development phase, and the technology is now ready for full-scale testing, the company said July 4.

Siemens began the R&D initiative in Oct. 2008 when it built a demonstration plant in Singapore to bring seawater to drinking water quality. Seawater is becoming increasingly important in replenishing the drinking-water supply in Singapore, Siemens says. But to desalinate it for potable use is an extremely energy-intensive process.

The results, which were presented at Singapore International Water Week, show the new process reduces desalting energy by more than 50%.

Siemens expects to implement a full-scale system by 2013 in cooperation with Singapore’s national water agency.
