Abstract

An improved method for treating cellulosic material recovered from a discrefiner in a mechanical pulp making process. Latency removal is conducted at a medium consistency of from about 8 to 15 percent in a medium consistency pump after which the suspension is removed at the same consistency to the storage tank. Screening and cleaning then take place at a low consistency. The method affords efficiencies in the nature of reduced capital costs and energy consumption.
