Plate dimensions, pressure filters

The same filter cloth material is to be used in a plate and frame filter press, each frame having dimensions 0.5 m x 0.5 m x 0.08 m, to filter the same slurry. The flow rate of slurry per unit area of cloth during the initial constant rate period is to be the same as that used in the preliminary experiment and the constant rate period is to be followed by constant pressure operation once the pressure reaches 8 x lO Nm". If the volume of cake formed per unit volume of filtrate, v is 0.02, calculate the time required to fill the frame. 

Example 14-2 A 20-frame (plate and frame filter) has dimensions (per frame) of 0.75 by 0.75 m and a thickness of 0.064 m. If this system is used for the slurry of Example 14-1 find the volume of slurry and time for filtration at a constant pressure of 2.76 x 10 pascals. Effective filtering area per frame is 0.87 m. ...
