Cake specific

Size a Nutsch filter for processing a suspension containing 15 % solids. The desired cake wetness is 45 % and the filter capacity for the filtrate should be 5 mVhr. The allowable pressure drop is 500 mm Hg. The cake specific resistance is r = 9 X 1011 m and the filter plate resistance is Rf = 2 x 10 ...

Thus if the liquid viscosity, filter area, filtration pressure and mass of dry cake per unit volume of filtrate, either from Equation (2.17) or (2.18), are known, the graphical values can be used to calculate the cake specific resistance and filter medium resistance.

Filtration tests can be carried out with quite simple apparatus where the objectives are principally twofold. Firstly, cake formation rate is required for preliminary equipment selection, and secondly parameters such as cake specific resistance and solids concentration values are needed, ideally as functions of the applied pressure/vacuum, for filter sizing and filtration rate calculations (Tarleton, 1998a,b Tarleton and Wakeman, 1994c, 1999 Wakeman and Tarleton, 1990, 1991a, 1994a). 

Determine the filtrate volume equivalent in resistance to the filter medium and piping (Vj), the specific cake resistance (a), the cake porosity (e), and the cake specific surface (5q).

If Vi is assumed to be zero, then Equation 12.9 results in Equation 12.10. This equation can be used to find the values of cake specific resistance and media resistance from...
