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 ...

Mathematical modelling has proven to be very useful in process design, operation and optimisation. A recent trend in WWTP modelling is to include the different subunits in so-called plant-wide models rather than focusing on parts of the entire process. One example of a typical plant-wide model is the coupling of an upstream activated sludge plant (including primary settler, and secondary clarif...

Current mechanistic anaerobic digestion (AD) models cannot accurately represent the underlying processes occurring during food waste (FW) AD. This work presents an update of Anaerobic Digestion Model no. 1 (ADM1) to provide accurate estimations free ammonia concentrations and related inhibition thresholds, model syntrophic acetate oxidation as acetate-consuming pathway. A modified Davies equati...

In order to deal with the environmental problems associated with animal production industrialization and at the same time considering energy costs increasing, a piggery wastewater treatment process consisting of combined anaerobic digestion and biological nitrogen removal by activated sludge was developed. This contribution presents a modelling framework in order to optimize this process. Modif...

The IWA Anaerobic Digestion Model No. 1 (ADM1) was chosen to simulate a two-stage anaerobic digestion lab-scale plant treating domestic wastewater. Initially, the model was preliminary tested using synthetic wastewater. The simulation results were satisfactorily compared to NH4 and chemical oxygen demand (COD) data for the first and second stages, respectively. A transformation method was then ...

In order to calibrate the model parameters, Sensitivity Analysis routines are mandatory rank parameters by their relevance and fix nominal values least influential factors. Despite high number of works based on ADM1, very few related sensitivity analysis. this study Global (GSA) Uncertainty Quantification (UQ) for an ADM1-based Anaerobic Digestion Model have been performed. The modified version...

Pyrolyzing biosolids can decrease volume and increase value of solids while anaerobic digestion gas liquids from the process could overall methane production. Prediction behavior biogas yield through simulation is valuable when considering new substrates for digestion. In this study, pyrolysis were implemented in Anaerobic Digestion Model No 1 (ADM1) together with a stream thermally hydrolyzed ...

Adrenomedullin (ADM) and calcitonin gene-related peptide (CGRP) receptors and their respective ligands play important roles in cardiovascular (patho-)physiology. Functional expression of ADM and CGRP receptors requires the presence of the calcitonin receptor-like receptor (CRLR) together with receptor-activity-modifying proteins (RAMPs). We have characterized the expression patterns of CRLR and...
