Abstract
Anaerobic digestion (AD) of organic waste requires pretreatment to improve its performance. The substrate chosen for this study is easily degradable it's from a University canteen in Morocco. This process was studied at the laboratory scale, under mesophilic conditions, using a mixed stirred reactor (CSTR: Continuous Stirred-Tank Reactor). The main objective of this research is to study the effect of ultrasonic pre-treatment on methane production. After ultrasonic pretreatment, the waste showed a decrease in VS from 156.2 g/Kg (93.75%) to 134.03 g/Kg (92.95%) and the recorded methanogenic potential was in the order of 461 (NmL CH4/g VS added), which is a 31% improvement compared to the methanogenic potential recorded by an experiment without ultrasonic pretreatment. Thus the process operated under good pH and alkalinity conditions.
