AbstractPilot validation trials for the anaerobic digestion of microalgae (Scenedesmus sp) were carried out on a UASB reactor (500 L). The trials took place continuously over a period of 3.5 months (102 days). The obtained biomethane generation efficiency (defined as the volume of biomethane produced per theoretical methane that could be stoichiometrically produced) was found to be above 60% for a hydraulic residence time (HRT) of 3.8 days. Biochemical methane potential (BMP) analysis confirmed the biomethane generation efficiency (both at low and high HRT) obtained with the pilot UASB reactor.
