Models and ADM1 for stabilized sewage sludge by anaerobic digestion process

Abstract

Due to the process and model complexity, number of available modelling studies in literature related to anaerobic processes used for the stabilization of sewage sludge are limited. Reliable dynamic modelling approaches provides important information about monitoring the process, prediction of process behavior by better understanding and defining mechanisms of process dynamic, developing the control algorithms and designing easily. In this study, basic substrate characterization models, secondary substrate characterization models and advanced level substrate characterization models are introduced which are used in modelling of stabilization of sewage sludge via anaerobic digestion along with the process of anaerobic digestion. Finally, available studies in the literature are summarized in detail related to Anaerobic Digestion Model (ADM1), ADM1 applications and modifications, and modelling of sewage sludge via ADM1.
