Biomethanation
Biomethanation is a general term for all the biological methods used for the production of methane biogas.
The methods available for biomethanation are:
- Anaerobic Digestion in digestors (most of this web site is devoted to this method and it is also discussed below);
- Methanogenesis in landfills. (For more information visit this Landfill Gas web site.)
- Upflow Anaerobic Sludge Blanket Process (UASB): (More ...)
Biomethanation by Anaerobic Digestion
There are a variety of different Anaerobic Digestion (AD) technologies available and the most well established are described in the standard water treatment textbooks. However, there is a new role for these processes as energy generators.
Historically, the most accomplished in AD Technologies have been the Chinese at the most simple low technology (mostly community and domestic) level - usually for gas supplies for cooking from sewage using AD.
Nowadays, in the large scale commercial Municipal Solid Waste (MSW) to energy market, there are an increasing number of European Companies emerging which have developed AD for MSW, over the past 10 to 20 years, who use variations of the AD process.
