Prediction of leaching and filtration performance of drum filters

White D.A. (1976)


The basic equations of filtration and cake washing are combined together to provide a complete model for a drum filter operating under floodwash conditions. The steady state operating data can be made to yield information on the performance of the unit under changing operating variables. For efficient washing of the cake the importance of vacuum, cake permeability and temperature control are indicated. Under floodwash conditions it is usually advantageous not to mix the feed pulp with excess wash water. © 1976.
