Abstract
The present invention provides a method () of separating pulp from a feed material within a tank (), the method comprising the steps of () introducing the feed material () into the tank (); () allowing the feed material () to settle in the tank (); () allowing the pulp () to form into aggregates (); () allowing the pulp aggregates () to settle towards the bottom of the tank () and form a networked layer () of pulp; and () causing a disturbance substantially uniformly across a disturbance zone () in an upper region of the networked layer (), so as to disrupt the networked pulp in the disturbance zone within a predetermined period of time; thereby releasing entrained liquid from the networked pulp in the disturbance zone () and increasing the relative density of the pulp below the disturbance zone. The invention also provides a separation device () for separating pulp () from a feed material ().
