Filtration Modeling of a Plate-And-Frame-Press
Plate-and-frame presses are used frequently in solid-liquid separation processes (Avery, 1988). After emptying the cake from a cell of a plate-and-frame press from a prior filtration cycle, a suspension is pumped under pressure into an empty cell. During this period, some filtration occurs. After filling the cell, filtration proceeds as
