Energy-neutral used water treatment – developed in Singapore

02 Jul 2012  


Increasing energy production while decreasing energy demand: this vision will soon become reality for used water treatment plants retrofitted with a novel concept developed by Singapore researchers in cooperation with international collaborators from Denmark and France. Hitting the spot in times of global warming, rising energy prices and increased urbanisation, the revamped plants shall not only become energy self-sufficient, but even generate excess energy.

On July 4, the international partners of the project signed a Research Collaboration Agreement formalising the alliance at the Singapore International Water Week (SIWW) 2012, the global platform for the sharing and co-creation of water solutions.

The Energy+-concept uses a two-step approach: A range of process manipulations help reducing the energy intensive conventional activated sludge process. At the same time, controlled anaerobic digestion allows to maximize the production of biogas, which can then be reused in the plant.

“With new and stricter international requirements on energy consumption and greenhouse gas emissions, the water sector has put energy efficiency high on the agenda”, explains Martin Andersen, Head of the Environmental Technology Department at DHI Singapore and Principal Investigator for the project. “There is an enormous market in minimising energy consumption of existing plants and making them, at least, energy neutral."

Event details:
The signing ceremony has taken place in the ‘Singapore International Water Week’ -Water Expo at Booth no. 32 (SUEZ ENVIRONNEMENT) - on Wednesday 4th July at 12.30 pm. Contact us to learn more about our fruitful collaboration and Energy+.
