Modeling of Thermophilic Anaerobic Digestion of Municipal Sludge Waste using Anaerobic Digestion Model No. 1 (ADM1)

Modeling anaerobic digestion of microalgae using ADM1.

The coupling between a microalgal pond and an anaerobic digester is a promising alternative for sustainable energy production by transforming carbon dioxide into methane using solar energy. In this paper, we demonstrate the ability of the original ADM1 model and a modified version (based on Contois kinetics for the hydrolysis steps) to represent microalgae anaerobic digestion. Simulations were ...

biokinetics of anaerobic digestion of municipal waste

a study of the biokinetics of anaerobic digestion of municipal solid waste (msw) was carried out using anaerobic batch digester. from the experimental results, the kinetic parameters (coefficient values) of the digestion of the msw were determined. the maximum rate of substrate utilization (k), saturation constant (ks), endogenous decay coefficient (kd), biomass yield or microbial growth yield ...

Interfacing the Iwa Anaerobic Digestion Model No.1 (adm1) with Manure and Solid Waste Characteristics

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...

Modeling of Anaerobic Digestion of Complex Substrates

A structured mathematical model of anaerobic conversion of complex organic materials in non-ideally cyclic-batch reactors for biogas production has been developed. The  model is based on multiple-reaction stoichiometry (enzymatic hydrolysis, acidogenesis, acetogenesis and methanogenesis), microbial growth kinetics, conventional material balances in the liquid and gas phases for a cyclic-bat...
