Abstract

Procédé pour la filtration de pâte à papier au moyen d'un appareil qui comporte un rotor et un stator; l'un des deux, le filtre (1), comporte des perçages de types fentes ou trous et l'autre, le décolmateur, comporte des moyens destinés à générer des pulsations de pression; consistant à contrer le colmatage progressif des perçages du filtre et la floculation progressive de la pâte lors du cheminement de la pâte entre le rotor et le stator en créant des zones de défloculation et/ou d'augmentation de la vitesse relative entre la pâte et le décolmateur.
