Warm Weather turns Waste Water into Biogas
June 7, 2007
Public Utilities Board (PUB) carries out successful experiment
Singapore’s warm weather speeds up the anaerobic waste-water treatment i.e. water treatment without oxygen. Waste water ferments faster and produces a mixture of methane and carbon dioxide (biogas).
Biogas produces power.
The Public Utilities Board (PUB) has been carry out laboratory tests and the results have been promising. PUB hopes to power 25% of its water treatment plant using this method.
The next step is pilot testing and a large-scale test plant. Roll out is still years away.
