| Abstract
|
The Upflow Anaerobic Sludge Blanket (UASB) is essentially based on a special flow regime allowing the sewage to get into contact with a „sludge blanket“ or “sludge bed” situated in the reactor, and a following 3- phase-separation of water, sludge and gas (methane). Within the sludge bed, the organic matter in the sewage is reduced by bacteria. In the anaerobic milieu of the reactor, the methane is formed due to bacterial activity during the fermentation process, which can be utilised as energy source. In order to achieve the best performance of the reactor, several parameters such as COD (Chemical Oxygen Demand), required retention time and others have to be taken into consideration.
