Introduction
With a PhD in process engineering from the University of Rennes 1 (France), Younès Bareha is specialized in the treatment of municipal, industrial and agricultural effluents by anaerobic biological processes. During his Ph.D. and post-doctoral positions, he participated in the effort to understand the transformations of nitrogen and phosphorus during anaerobic processes (anaerobic digestion and dark fermentation) combining an experimental and numerical approach.

Article
Up to half of the organic fraction of an urban wastewater is made up of particulate settleable solids (PSS). In activated sludge process (AS) this material is rapidly adsorbed on to microbial flocs but is only slowly and partially degraded. To better understand and predict the degradation kinetics observed, a determination of the proportion of hydr...
Article
Prediction of organic nitrogen mineralization into ammonium during anaerobic digestion is required for optimizing substitution of mineral fertilizer by digestates. The aim of this study was to understand organic nitrogen biodegradability and to investigate how it can be predicted from carbon biodegradability, and nitrogen bioaccessibility, respecti...
Article
Full-text available
Simulating the fate of nitrogen during anaerobic digestion is required to predict the characteristics of digestates and to improve their exploitation for agricultural uses. The aim of this study was to develop a modified ADM1 model that includes bioaccessibility-based fractionation to accurately simulate the fate of nitrogen during anaerobic digest...
Article
Full-text available
In this paper, nitrogen transformations were studied on 13 substrates from agro-industrial, agricultural or urban sources using a new method. This method was developed to determine the kinetics and balance of nitrogen transformation during anaerobic digestion with high inoculum-to-substrate ratio while avoiding instabilities with nutrients addition...
Thesis
Full-text available
La valorisation des déchets par digestion anaérobie conduit à la production d’un résidu, appelé digestat, qui est composé de la matière organique non biodégradée et présente une forte teneur en azote ammoniacal et organique. De par cette richesse en azote, les digestats présentent un intérêt grandissant pour la substitution aux engrais minéraux. L’...
Article
To reduce greenhouse gas emissions from organic waste, anaerobic digestion has created new opportunities for energy and nutrient recovery from these wastes. However, the use of certain organic wastes in anaerobic digestion is limited due to their atypical physicochemical characteristics (e.g. unbalanced carbon to nitrogen ratio, high ash concentrat...
Article
The increase in anaerobic digestion systems has profoundly affected the waste management of territories, particularly for agricultural systems. Changes in cultural practices and imports of organic waste modify the carbon (C) and nitrogen (N) fluxes on territories where anaerobic digestion is implemented. Successful anaerobic digestion can increase...
Data
L'outil Sys-Metha permet de prédire : (1) les flux de carbone et d’azote sur les filières de méthanisation et (2) les caractéristiques du ou des digestats produits. L’outil a été développé pour les filières de méthanisation en voie liquide et considère les étapes de méthanisation, séparation de phase et stockage. L'outil est composé de quatre modul...
Article
Full-text available
Recycling phosphorus from waste activated sludge has attracted a lot of interest to tackle the problem of phosphorus stocks depletion and the increase in food demand. In this study, the use of fermentation processes was investigated to enhance phosphorus dissolution from waste activated sludge to improve its recycling. Two fermentation processes, b...

Full-text available
The increased demand for fertilizers and the rock Phosphorus (P) depletion has raised the awareness of the scientific community in the last decade, especially in Europe where the rock P is very limited. During this period, several European projects have been set up to find a sustainable solution for Phosphorus demand. The Phos4You* project objectiv...
Conference Paper
Full-text available
Prediction of the ammonium content of digestates is a great challenge to optimize : (i) design and management of the anaerobic process in order to prevent inhibition due to ammonia into the digester; (ii) design and management of digestate post-processings such as ammonia stripping or struvite precipitation. (iii) agricultural recovery of digestate...
Conference Paper
Full-text available
Prediction of the nitrogen properties of digestates is a great challenge to better manage the anaerobic process, post-treatments and agricultural recovery of digestates. The aim of this study is to understand organic nitrogen accessibility and its anaerobic biodegradability in order to better predict nitrogen characteristics of digestates (ammonium...
