ABSTRACT:
A method and apparatus for effecting washing, bleaching, or thickening, etcetera of paper pulp or the like utilizes stationary screens, yet provides efficient treatment without significant screen clogging. Pulp introduced into the bottom of a cylindrical upright vessel is caused to flow in particular radial segments and channels. Introduction of pulp into all channels of a particular radial segment, extraction of withdrawn liquid from the radial segments, removal of treated pulp from the top of the vessel, and the introduction of treating liquid between the stationary screens, are coordinated so that uniform treatment of the upwardly flowing pulp results.
