Type d’épaississeur constitué essentiellement d’un bac à pâte à l'intérieur duquel baigne partiellement un tambour filtrant rotatif. La pâte épaissie adhère à la surface du tambour tandis que l'eau traverse la paroi de ce dernier sous l'effet de la gravité. 3, record 1, French, - %C3%A9paississeur%20par%20gravit%C3%A9

The process of separating soluble, undesirable impurity components of pulp slurries from the fibers. Normally this is done after cooking, and in and after the bleaching operation by the use of some method of screening combined with the use of fresh water and other liquids. 2, record 2, English, - washing
Record number: 2, Textual support number: 1 CONT
The soluble impurities impede the efficiency of the next bleaching stage by increasing the consumption of chemicals and aggravate brightness reversion if not removed after a final stage. Washing in a bleach plant takes place by dilution, whereby the pulp is alternately diluted and thickened; or by displacement, in which the liquor containing the impurities is displaced by adding a limited amount of water on a thickened pulp mat. 3, record 2, English, - washing

À la fin de chaque stade de blanchiment, le matelas de pâte est lavé afin d’en extraire les impuretés solubles qui se sont formées pendant la réaction de blanchiment. Ces impuretés solubles nuisent à l'efficacité du stade de blanchiment suivant en augmentant la consommation de produits chimiques. De plus, elles accentuent la perte de blancheur après le stade final. Le lavage s’effectue par dilution et épaississement successifs ou par des réactions de substitution qui consistent à déplacer les molécules de la liqueur contaminée par une quantité minimale d’eau dans le matelas de pâte épaissie. 2, record 2, French, - lavage

For simple thickening of very dilute stocks up to 12% consistency, multidisc thickeners ... can be used. A fiber mat forms on the face of each sector as it submerges in the vat of stock. After complete submergence, vacuum is applied and more pulp is deposited while filtrate is drawn through the mat. The initial filtrate is relatively cloudy and can be segregated (by the action of the end valve) for dilution uses. The later (clear) filtrate is sufficiently free of fiber to be used for shower water. Following emergence from the vat, the pulp mat is further dewatered and finally removed from the filter media by a knockoff shower. Multidisc thickeners are most commonly used as save all devices, i.e., to recover fine fibers from white water and reuse the water. 1, record 3, English, - multidisc%20thickener

Pour obtenir un épaississage à une concentration ne dépassant pas 12 %, on peut faire appel à des épaississeurs à disques [...] Un matelas fibreux se forme à la surface de chacun des segments à mesure que ceux-ci plongent dans la cuve de pâte. Après immersion complète, un vide est appliqué qui entraîne un dépôt supplémentaire de pâte, tandis que le filtrat est aspiré à travers le matelas. Le premier filtrat est relativement trouble et peut être isolé(par l'appareil de robinetterie d’extrémité) aux fins de dilution. Le filtrat subséquent(plus clair) possède une teneur en fibres suffisamment faible pour servir d’eau de rinçage. À sa sortie de la cuve, la couche de pâte continue d’être épaissie, puis est enfin détachée du disque filtrant au moyen d’un rinceur de choc. 1, record 3, French, - %C3%A9paississeur%20%C3%A0%20disques

Procédé basé sur la coagulation thermique de la boue. La boue chauffée à des températures comprises entre 150 et 200°C subit une transformation irréversible. Sa structure colloïdale est détruite ainsi que son affinité pour l'eau dont elle se sépare par simple décantation. La boue épaissie et recueillie est facilement déshydratable sur filtres-presses ou filtres à vide. 1, record 4, French, - proc%C3%A9d%C3%A9%20Porteous
