A method for washing pulp in a multistage pulp washing operation involves controlling operating conditions so as to maximize the efficiency of the operation particularly in response to determination of the percent consistency off the discharge side of each drum washer. The major variables that are useful to control are vat dilution flow, drum speed, vat level set point, drainage aids or defoamers, press roll pressures, vacuum break position, and temperature of the last stage showers.

Méthode de lavage de la pâte selon une opération multiphases. Elle consiste à contrôler les conditions d'opérations afin de maximiser leur efficacité, particulièrement en réponse à la détermination de la cohérence de pourcentage du côté du déchargement de chaque pile laveuse à tambour. Les principales variables qui sont utiles pour ce contrôle sont : l'écoulement de dilution en cuve; la vitesse de rotation des cylindres; le point de consigne du niveau de la cuve; les séquestrants ou les anti-mousse; la pression des rouleaux de presse; la position de bris du vide; la température des rinçages de dernière étape.
