Abstract
Des techniques pour déterminer un dosage dagent de floculation et ajuster les paramètres de fonctionnement du procédé pour une opération de déshydratation de résidus fins et épais sont décrites. Les techniques peuvent consister à déterminer les caractéristiques de déshydratation dun échantillon de résidus floculés conditionnés, ce qui comprend la mesure dune libération deau nette à légard des résidus fins et épais et lajustement dau moins un état de fonctionnement conformément à la libération deau nette mesurée. Lessai de dosage de lagent de floculation peut comprendre la détermination dun dosage approximatif de lagent de floculation requis pour transformer un échantillon des résidus fins et épais en un échantillon de résidus floculés conditionnés ayant une libération deau nette mesurée positive en réponse à un conditionnement par cisaillement au-delà dune valeur de limite délasticité statique maximale. De multiples phases et balayages peuvent être effectués afin de permettre à lessai de dosage de lagent de floculation de déterminer le dosage optimal pour la libération de leau.
