Fumiers de bovins, une ressource à fort potentiel pour la filière de méthanisation en France ? [PDF]
Sciences, Eaux & Territoires, 2016 En France, la méthanisation agricole représente l'un des principaux leviers d’action pour atteindre les objectifs « biogaz » dans la production d’énergies renouvelables.

Effect of ultrasonic, thermal and ozone pre-treatments on waste activated sludge solubilisation and anaerobic biodegradability [PDF]
, 2006 In order to enhance the efficiency of anaerobic digestion, the effects of ultrasounds, ozonation and thermal pre-treatment have been studied on waste activated sludge.

Modeling CO2 capture processes by chemical absorption: The case of biogas treatment [PDF]
E3S Web of Conferences, 2021 Our objective through this work is to purify the biogas produced by a methanisation process in order to be valorized in a cogeneration unit. The studied biogas is mainly composed of methane 60% and carbon dioxide 39%.

Production de spiruline à la ferme : produire de la spiruline à la ferme grâce au digestat et à la chaleur excédentaire d’une installation de biogaz [PDF]
, 2015 The development of projects coupling an agricultural anaerobic digestion installation with the production of spirulina is an attractive concept, since the waste streams from the methanisation and from biogas valorization can be used to produce a high ...

Silage of the organic fraction of municipal solid waste to improve methane production
Water Science and Technology, 2021 The silage of the organic fraction of municipal solid waste (OFMSW) is a common practice in biogas plants. During silage, fermentation processes take place, affecting the later methanisation stage.

Journal of Combustion, Volume 2014, Issue 1, 2014., 2014 The updraft gasifier is a simple type of reactor for the gasification of biomass that is easy to operate and has high conversion efficiency, although it produces high levels of tar. This study attempts to observe the performance of a modified updraft gasifier.

Anaerobic Treatment of Concentrated Black Water in UASB Reactor at a Short HRT [PDF]
This research describes the feasibility of applying a UASB reactor for the treatment of concentrated black (toilet) water at 25 °C. On average 78% of the influent load of COD at an HRT of 8.7 days was removed. Produced methane can be converted to 56 MJ/p/

Mathematical Problems in Engineering, Volume 2013, Issue 1, 2013., 2013 This paper shows a study, both analytical and numerical, of a continuous‐time dynamical system associated with a simple model of a wastewater biorreactor. Nonsmooth phenomena and border‐collision local bifurcations appear when the main parameters (dilution and biomass concentration at the inflow) are varied.
