Article
Wastewater treatment using oxygenic photogranule-based process has lower environmental impact than conventional activated sludge process, Bioresource Technology (2020), doi: https://doi. Abstract: The Life Cycle Assessment (LCA) methodology was applied to assess the environmental feasibility of a novel wastewater treatment technology based on oxyge...
Article
Agricultural utilization of organic residues is often included in Life cycle assessment (LCA) studies on livestock and crop production as well as waste and wastewater treatment. A review on the current state-of-the-art practices in agricultural use of organic residues in LCA studies is presented. This reveals that agricultural use of organic residu...

A researcher or practitioner can employ a biofilm model to gain insight into what controls the performance of a biofilm process and for optimizing its performance. While a wide range of biofilm-modeling platforms are available, a good strategy is to choose the simplest model that includes sufficient components and processes to address the modeling...
Conference Paper
Full-text available
The goal of this study was to evaluate the applicability of the framework for good biofilm reactor modelling practice (GBRMP), presented at WWTmod2012, to modelling both MBBR and IFAS systems using a commercial WWTP simulation tool. We tested the previously proposed calibration protocol using data from a pilot-scale MBBR and a pilot-scale IFAS plan...
Article
Full-text available
One-dimensional biofilm models have been demonstrated accurate for modeling specific types of biofilm reactors; in particular those using free-moving submerged biofilm carriers (X carrier). Biofilm reactors containing X carrier are presently the most widely applied biofilm-based system for municipal and industrial wastewater treatment. This paper p...
Article
Full-text available
Algae are an attractive, alternative renewable source for biofuel production compared to biomass from food crops or cellulosic materials. Marine algae do not need fresh water or arable land and, thus, production of marine algae does not compete with food production. In contrast to biofuel production from microalgae, the use of macroalgal biomass as...

Book
This work is a review of Life Cycle Assessment (LCA) studies dealing with agricultural use of fertilizing residues (FR). The majority of the studies were dedicated to LCA of waste and wastewater treatment systems and, in few cases, to agricultural productions. In most of the studies on LCA of waste and wastewater treatment, FR spreading induces tox...
Conference Paper
This study aimed at evaluating the anaerobic digestion performance and biogas production from microalgal biomass grown in high rate algal ponds (HRAP) for wastewater treatment. Experimental results obtained in lab-scale reactors indicated that the methane yield increased with HRT, reaching 0.21 L CH4/g COD when anaerobic reactors were operated at 2...
Book
L'effet de la teneur en solides sur les performances sur la digestion anaérobie a été étudié expérimentalement en faisant varier la teneur en Matières Sèches (MS) allant de 10 à 35%. Une inhibition de la méthanogénèse a été observée pour des teneurs en MS élevées (> 30%). Le modèle de digestion anaérobie ADM1 a ensuite été utilisé pour décrire les...
Article

This paper summarizes part of the research work carried out in the Add Control project, which proposes an extension of the wastewater treatment plant (WWTP) models and modelling architectures used in traditional WWTP simulation tools, addressing, in addition to the classical mass transformations (transport, physico-chemical phenomena, biological re...
Article
Mathematical models are useful tools for studying and exploring biological conversion processes as well as microbial competition in biological treatment processes. A single-species biofilm model was used to describe biofilm reactor operation at three different hydraulic retention times (HRT). The single-species biofilm model was calibrated with spa...
Conference Paper
Full-text available
Many wastewater treatment plant (WWTP) simulators include biofilm reactor modules, enabling a more widespread application of biofilm models in engineering practice. To increase acceptance, and promote proper and effective biofilm model use in practice, a framework for biofilm reactor model calibration and application is needed. A step-wise calibrat...
Conference Paper

This paper summarises part of the research work carried out in the Add Control project, which proposes an extension of the WWTP models and modelling architectures used in traditional WWTP simulation tools addressing next to the classical mass transformations (transport, physico-chemical phenomena, biological reactions), all the instrumentation, act...
Article
Full-text available
Biofilm models are valuable tools for the design and evaluation of biofilm-based processes despite several uncertainties including the dynamics and rate of biofilm detachment, concentration gradients external to the biofilm surface, and undefined biofilm reactor model calibration protocol. The present investigation serves to (1) systematically eval...
Conference Paper
Full-text available
This paper addresses the mathematical modelling of wastewater treatment plants (WWTPs) extending the traditional WWTP models by considering not only the actual treatment processes but also the associated measurement, actuation and control equipment. Thus, a three-layer, component-based modelling architecture replicating a complete WWTP is presented...
Article
Full-text available
Instrumentation, control, and automation (ICA) in wastewater treatment enables the improvement of treatment plant performance without structural modifications of the plant. Even for wastewater treatment plants (WWTPs) meeting all criteria with respect to effluent concentrations and sludge disposal, ICA can be of interest as it can help to reduce en...
Conference Paper
Full-text available
Biofilm reactors are an emerging environmental biotechnology used for the removal of selenium from industrial wastewater. Bioreactor models for selenium removal that are based on the mechanistic description of biofilms are few in number, but a dynamic model that is based on mechanistic principles (chemical and biochemical) and is capable of describ...
Article
Full-text available
In practice, partial nitrification to nitrite in biofilms has been achieved with a range of different operating conditions, but mechanisms resulting in reliable partial nitrification in biofilms are not well understood. In this study, mathematical biofilm modeling combined with Monte Carlo filtering was used to evaluate operating conditions that (1...

Biofilm models are valuable tools for process engineers despite several uncertainties including the dynamics and rate of biofilm detachment, concentration gradients external to the biofilm surface, and undefined biofilm reactor model calibration protocol. The present investigation serves to (1) evaluate two ad hoc model calibration procedures, (2)...
Article
Full-text available
Parameter estimation and model calibration are key problems in the application of biofilm models in engineering practice, where a large number of model parameters need to be determined usually based on experimental data with only limited information content. In this article, identifiability of biokinetic parameters of a biofilm model describing two...
Conference Paper
Full-text available
A modeling study was carried out to evaluate the relevance of inhibition by free ammonia on partial nitrification of ammonium-rich wastewater in combination with competition for oxygen and space by ammonium and nitrite oxidizing bacteria (AOB and NOB) in biofilms. Start-up as well as long-term operation were evaluated with and without considering i...
Article
Full-text available
Two different methods for global sensitivity analysis were compared exemplarily for a biofilm model for two-step nitrification. Especially for biofilm models, local sensitivity analysis is not very useful as parameters can vary over a large range. Parameters that were evaluated included kinetic and stoichiometric parameters, and also biofilm parame...
Article
Full-text available
A systematic approach to estimate and evaluate parameters for deammonification in biofilms from available experimental data was evaluated. Parameter estimation was based on a regional steady state sensitivity analysis to select relevant parameters and design of experiments based on a local identifiability analysis. The calibrated model was evaluate...
Article
A procedure for selecting parameters for identifiability analysis and parameter estimation and for the design of experiments as a basis for parameter estimation was described for a model of deammonification in biofilm systems. A larger number of parameters were identifiable using data from batch experiments than from continuous reactor operation. H...
