Abstract
L'invention concerne des systèmes et des procédés d'épuration par hydrocyclone, permettant d'enlever les impuretés dans une suspension de pâte à papier. Un sous-système (10) utilise des épurateurs à sortie de rejets inférieure conçus pour enlever les impuretés grossières, et alimente directement un autre sous-système (12) conçu pour enlever les impuretés légères. Le sous-système (12) comporte également un épurateur à écoulement traversant qui reçoit le flux de rejets provenant d'un épurateur primaire à sortie de rejets supérieure, les deux systèmes étant reliés à un système de réservoir d'équilibre (15) commun. Ces deux sous-systèmes fonctionnent avec des concentrations faibles ou à rendement élevé alors que l'épurateur primaire à écoulement traversant du sous-système assure une production de sortie dans le système présentant une concentration environ deux fois plus élevée que celle de l'entrée de sorte que l'opération globale permette d'assurer l'épuration de la suspension de pâte à papier et son épaississement.
