In this study, the IWA anaerobic digestion model N°1 (ADM1) was used to simulate and predict the dark fermentation process of a complex organic substrate: household waste. Since ADM1 does not account for metabolic products such as lactic acid, ethanol and some volatiles fatty acids like caproate, that appear during the dark fermentation process, the structure of ADM1 was modified to include the...

Anaerobic digestion of organic waste plays an important role for the development of sustainable energy supply based on renewable resources. For further process optimization of anaerobic digestion, biogas production with the commonly used substrates, grass, maize, and green weed silage, together with industrial glycerine, were analyzed by the Weender analysis/van Soest method, and a simulation s...

First-order and ADM1 modeling approaches were compared to evaluate the effects of a novel pretreatment technique, autohydrolysis, in the anaerobic digestion of waste activated sludge (WAS). Hydrolysis constant rates were calibrated using data from biochemical methane potential (BMP) tests and validated using data from continuous digesters fed with raw and pretreated WAS. Results indicated that ...

Anaerobic digestion model No.1 (ADM1) was applied and expanded in this study to model and simulate anaerobic digestion (AD) of an industrial carbon capture reclaimer MEA (monoethanolamine) waste (MEAw) together with easily degradable organics. The general structure of ADM1 was not changed except for introducing state variables of MEA and complex organics (CO) in the waste and biochemical reacti...

OBJECTIVE To investigate grey (GM) and white matter (WM) abnormalities and their effects on cognitive and behavioral deficits in a large, phenotypically and genotypically well-characterized cohort of classic adult (aDM1, age at onset ≥ 20 years) or juvenile (jDM1, age at onset <20 years) patients with myotonic dystrophy type 1 (DM1). METHODS A case-control study including 51 DM1 patients (17 ...

The IWA Anaerobic Digestion Model No.1 (ADM1) was presented in 2002 and is expected to represent the state-of-the-art model within this field in the future. Due to its complexity the implementation of the model is not a simple task and several computational aspects need to be considered, in particular if the ADM1 is to be included in dynamic simulations of plant-wide or even integrated systems....

Improving anaerobic digestion of sewage sludge through pretreatment techniques is a suitable solution for better sludge management. In this sense, modeling may present itself as an important tool to assess and predict process performance and pretreatment effects. In this study, the feasibility of using biochemical methane potential (BMP) tests data for calibrating the Anaerobic Digestion Model ...

The IWA Anaerobic Digestion Model No.1 (ADM1) was presented in 2002 and is expected to represent the state-of-the-art model within this field in the future. Due to its complexity and stiffness the implementation of the model is not a simple task and several computational aspects need to be considered, in particular if the ADM1 is to be included in dynamic simulations of plantwide or even integr...

An interface to ADM1 was developed to estimate the solid waste composition from its practical characteristics. The interface was based on COD, elemental, charge and covalent bond balances to conceal any error in collected characteristics from different sources. The interface was validated by reported characteristics of manure and food wastes and determined with relevant accuracy the wastes’ com...
