New perspectives in anaerobic digestion
Water Science and Technology, 2001 The IWA specialised group on anaerobic digestion (AD) is one of the oldest working groups of the former IAWQ organisation. Despite the fact that anaerobic technology dates back more than 100 years, the technology is still under development, adapting novel treatment systems to the modern requirements. In fact, most advances were achieved during the last

Observability and Identifiability Analyses of Process Models for Agricultural Anaerobic Digestion Plants [PDF]
arXiv, 2023 Dynamic operation of anaerobic digestion plants requires advanced process monitoring and control. Different simplifications of the Anaerobic Digestion Model No. 1 (ADM1) have been proposed recently, which appear promising for model-based process automation and state estimation.

Acid digestion and symbiont: Proton sharing at the origin of mitochondriogenesis?
BioEssays, Volume 45, Issue 1, January 2023., 2023 ADMit hypothesis for the origin of eukaryotes. A bacterial symbiont became associated with a protophagocytic host that captured prey with membrane processes. The symbiont cooperated to kill and digest the prey with reactive oxygen species and the acidification of the microenvironment.

Introducing CHAD -- An ADM1 Solver for Direct Linking to Lagrangian CFD Software [PDF]
arXiv, 2023 Standard methods for modeling anaerobic digestion processes assume homogeneous conditions inside the tank and thus suffer from the negligence of hydrodynamics. In this work, we present the software toolbox Coupled Hydrodynamics and Anaerobic Digestion (CHAD), a novel parallelized solver that is capable of utilizing CFD results as the basis for ...

Dynamic optimization of volatile fatty acids to enrich biohydrogen production using a deep learning neural network [PDF]
, 2022 A new strategy was developed to investigate the effect of volatile fatty acids (VFAs) on the efficiency of biogas production with a focus on improving bio-H$_2$. The inoculum used, anaerobic granular sludge obtained from a UASB reactor treating poultry slaughterhouse wastewater, was pretreated with five different pretreatments. The relationship between
