Béline, F. / Guiziou, F. / Daumer, M.L. / Loyon, L. - 2015In Britanny, land application of livestock wastes from confined animal operations is seen as a major source of nitrogen in agricultural drainage channels. In this context, treatment aiming at removal of nitrogen from livestock wastes, particularly pig slurry, is becoming increasingly common in...Contributeur (s):

Vedrenne, F. / Béline, F. / Bernet, N. - 2015A wide range of ultimate methane yield values are available for each animal specie in the literature. Organic matter compositions, biomass activity and potential inhibitors influence methane productions. Moreover, analytical practices could also have an effect on methane production determination....Contributeur (s):

Thirion, F. / Béline, F. / Saint-Cast, P. - 2015Before spreading, a complete mixing of the tank is necessary in order to apply an homogenous product and provide an even rate of nutrients in the field. The requirement on mixer performances can be determined according to yield velocity for lifting up the settled particles. Therefore manufacturers...Contributeur (s):

Loyon, L. / Béline, F. / Guiziou, F. / Boursier, H. / Peu, P. - 2015/ Ce rapport présente le développement d'un modèle permettant d'estimer les caractéristiques et les quantités de lisier brut porcin. Ce modèle est basé sur un bilan matière journalier dans la fosse de stockage et sur des caractéristiques de lisiers issus de la bibliographie. Les valeurs...Contributeur (s):

Loyon, L. / Guiziou, F. / Béline, F. / Peu, P. - 2015Biological aerobic treatment of pig slurry is one of the measures to limit land-application of manure. This treatment transforms the nitrogen compounds into N2 by nitrification and denitrification. However, this treatment may be a source of other gaseous emissions (NH3, CH4, N2O, CO2) emitted...Contributeur (s):

Loyon, L. / Guiziou, F. / Béline, F. - 2015This article present the preliminary results concerning the quantification of gaseous emissions from biological treatment systems of pig slurry including NH3, N2O, CH4 and CO2. The results relate to the gas emissions observed during the storage in field conditions of the different products of a...Contributeur (s):

Béline, F. - 2015The aim of this work was to develop and evaluate aeration as a strategy to reduce methane emissions during the storage of cattle slurry. For this purpose, a laboratory pilot including 3 storage reactors (9 litres each) was developed. One of them was equipped with an oxydo-reduction potential (ORP)...Contributeur (s):

Béline, F. / Sneath, R.W. / Peu, P. - 2015Estimation of greenhouse gas emissions (GHG) from storage of livestock manure have been made at laboratory or by using chamber techniques, which are point specific and interfere with conditions at the slurry-atmosphere interface. The aim of this work was to developed a method without environmental...Contributeur (s):

Peu, P. / Béline, F. / Martinez, J. - 2015A simple and sensitive liquid chromatography method designed to determine volatile fatty acids (VFA) content in pig slurry sample is proposed. The acids are isolated with a cation exchange column for carbohydrates using an isocratic phosphate eluant coupled with an ultraviolet detector in series....Contributeur (s):

Daumer, M.L. / Béline, F. / Guiziou, F. - 2015This book includes the main available technical knowledge on aerobic biological treatment of pig slurry. After a short introduction of the regimentation, technical informations are presented mainly on: - Pig slurry composition - Manure management before treatment - Separation devices - Biological...Contributeur (s):

Daumer, M.L. / Béline, F. / Guiziou, F. - 2015The fate of phosphorus distribution in the products obtained from biological aerobic treatment of pig slurry, e.g. separated solids, liquid effluent and sludge, was monitored in three different farm-scale units. Samples of raw slurry, solid products, aerated slurry, liquid effluent and sludge were...Contributeur (s):

Boursier, H. / Béline, F. / Paul, E. - 2015In intensive farming areas, the design of biological nitrogen removal plants for piggery wastewater requires the determination of the chemical oxygen demand (COD) fractions of the effluent. For this purpose, an experimental procedure was developed to quantify the inert soluble (SI) and particulate...Contributeur (s):

Boursier, H. / Béline, F. / Paul, E. - 2015To optimise the intermittent aeration process for piggery wastewater, the Activated Sludge Model N°1 needs to be calibrated and adapted to this specific effluent. By combining aerobic and anoxic respirometric tests, biodegradation kinetics of organic fractions in piggery wastewater could be studied...Contributeur (s):

Guiziou, F. / Béline, F. - 2015An experimental technique was developed for measuring gaseous emissions including ammonia (NH3), nitrous oxide (N2O) and methane (CH4) from broiler houses. This technique included the monitoring of the air flow rate and the gaseous concentrations. NH3 was determined using acid trap while N2O and...Contributeur (s):

Thirion, F. / Béline, F. / Saint-Cast, P. - 2015/ Le stockage du lisier a fait l'objet d'importants investissements dans le cadre des programmes de mise aux normes. Le brassage est nécessaire por assurer l'homogénéisation du lisier en vue de l'épandage. Cette étude présente les résultats d'une analyse générale du...Contributeur (s):
