Operational evaluation of rotary drum vacuum filters for brownstock washing using basic filtration parameters

摘要

A calculation procedure was developed for a rotary drum vacuum filter used in brownstock washing.In the model of a rotary drum vacuum filter,brownstock washing is split into a set of basic unit operations.These operations are described,combining mass balance equations with constant-pressure filtration equations.This set of equations is solved using the system/engineering methodology.The results for a typical rotary drum vacuum filter are presented.
