Béline, F. / Martinez, J. - 1997Aeration is a widely recognized treatment technique for the purification of livestock slurries. Several processes using this technique have been developed recently for nitrogen removal purposes. The nitrogen abatement could reach 60 to 70 % of the total initial nitrogen content of the raw slurry....Contributeur (s):

Béline, F. / Martinez, J. / Burton, C.H. - 1998Aeration of livestock slurries is a widespread treatment method which can deal with different pollution problems such as (i) control of odours, (ii) the degradation of organic carbon, (iii) the removal of nitrogen by nitrification-denitrification and (iv) the control of pathogens. After a resume of...Contributeur (s):

Béline, F. - 1998In some areas, aerobic treatment can deal with different pollution problem, more particularly with the water pollution by nitrate. During treatment, nitrogen is removed as nitrogen gaseous forms by nitrification and denitrification. However, transformations and transfer of nitrogen of the slurry to...Contributeur (s):

Béline, F. / Martinez, J. / Marol, C. / Guiraud, G. - 1998Different forms of nitrogen : dissolved inorganic-N (or total ammonium-N), suspended organic-N and dissolved organic-N were followed during anaerobic storage of N-15 labelled pig slurry. The kinetics of nitrogen transformations were recorded at 0, 1, 3, 7, 14, 28, 63 and 84 days during a laboratory...Contributeur (s):

Peu, P. / Béline, F. / Martinez, J. - 1999A floating rectangular polyvinyl chloride (PVC) open bottom chamber coupled with a molecular sieve trap was designed to measure the amounts of nitrous oxide gas (N20) emitted during aerobic treatment or storage of liquid animal slurries. A number of outdoor calibration trials, using water and a...Contributeur (s):

the effect of continuous and intermittent aerobic treatment of pig slurry on nitrous oxide emissionsBéline, F. / Martinez, J. - 1999A laboratory treatment system was designed to study the fate of nitrogen during aerobic treatment of pig slurry. Different aeration processes, continuous and intermittent, were evaluated. For each of the four runs evaluated, the nitrogen mass balance was determined including measurement of the...Contributeur (s):

Béline, F. / Martinez, J. / Chadwick, D.R. - 1998A laboratory treatment system was designed to study the fate of nitrogen during aerobic treatment of pig slurry. Different aeration strategies, and more particularly the influence of residence time and aeration level, were manipulated. A series of six experiments was carried out to determine the...Contributeur (s):

Béline, F. / Guiziou, F. / Peu, P. / Martinez, J. - 1999A floating chamber method was designed to measure the amounts of nitrous oxide gas (N2O) emitted during aerobic treatment of pig slurry. Measurement of nitrous oxide emissions from farm scale treatment units was completed by a monitoring of the dissolved nitrous oxide in slurry. The amounts of N2O...Contributeur (s):

Martinez, J. / Béline, F. - 1999This report describe a selection of 50 refereed papers on greenhouse gaseous emissions (CH4, N20) from the livestock sector (animal wastes). Each reference presented is sommarised as a standard form. The presentation include methodology on how to measure the emitted gases and on emissions factors...Contributeur (s):

Martinez, J. / Béline, F. / Peu, P. / Guiziou, F. - 1999Gaseous carbon emissions and particularly methane emissions rates were determined through a series of laboratory experiments comparing during a 50 days kinetic monitoring period, the losses from a range of liquid piggerry slurries, separated solids, poultry manures and compost. From pig slurries,...Contributeur (s):
