Summary: The study proposes a systematic procedure for successive model simplification based on the ADM1 for anaerobic digestion plants. It presents five model variants with different characteristics, simplifying the nutrient degradation and biogas formation. The complex model structures describe individual degradation pathways and intermediates during acido- and acetogenesis, while evaluating the stoichiometric methane potentials and microbial biomass yields of the underlying degradation pathways in detail.

Summary: A modified mathematical model was established to simulate the anaerobic bioconversion process of vegetable crop residues, with a focus on crystalline cellulose. The model successfully predicted methane production data of different VCRs, but further modifications and validations are needed for simulating other types of lignocellulosic waste.

Summary: Modification of the production chain is a common tactic in the biogas generation industry. Mathematical modeling provides great support in selecting the right reactor configuration and operational parameters. In this study, a simplified version of the Anaerobic Digestion Model No. 1 was adapted to a system with an external pump. The new model showed higher accuracy compared to previous models, and it was successfully applied in realistic scenarios.

Summary: This study investigated the role of sludge rheology in anaerobic digestion (AD) and found that rheological properties increased with the increase of solid content, resulting in a negative effect on methane production. An extended ADM1 model revealed that enhanced sludge rheological properties increased mass diffusion resistance and reduced uptake rate of acetate.

Summary: Anaerobic co-digestion is an effective method to overcome limitations in individual substrate digestion, but finding suitable substrate combinations requires extensive experimentation. In this study, a probabilistic framework using Anaerobic Digestion Model No. 1 was developed to estimate methane production potential from mixed substrates, and the framework was validated using agricultural residues as a case study. The results showed that co-digestion can increase mean methane content by up to 8% compared to mono-digestion. However, the predicted probability distributions were multimodal, highlighting the need for a probabilistic approach in anaerobic digestion modeling for accurate decision making.

Summary: In this study, Global Sensitivity Analysis (GSA) and Uncertainty Quantification (UQ) were conducted on an ADM1-based Anaerobic Digestion Model focused on municipal solid waste digestion. The model introduced a surface-based kinetic approach to better model the disintegration step of complex organic matter. GSA and UQ were essential for further improvements and a deeper understanding of the main processes and input factors.

Summary: Wastewater treatment plants (WWTPs) are crucial for maintaining water quality. This study presents an optimal operation approach for WWTPs considering quantitative and qualitative influent variables. The proposed method involves developing and calibrating a simulation model, classifying the influent using the k-means clustering method, and determining optimal operation parameters using the AMOEA-MAP optimization algorithm. The approach was implemented on a WWTP in Tehran, Iran, resulting in improved pollutant removal performance. Using this method, the effluent achieved reductions of 11-41% in COD, 17-20% in ammonium, and 15-34% in nitrate.
