Cake moisture correction—mass balance

In some cases, particularly in the filtration of highly concentrated suspensions, when working out the mass of dry cake from filtrate volume collected a cake moisture correction has to be applied, which accounts for the presence of moisture in the cake. The relationship that replaces equation 9.9 in such cases is obtained from solids concentration c (kg m ) in the original suspension and from the moisture content of the cake 

Comparison of equations 9.9 and 9.38 may be used to define a corrected concentration Ccorrected, i.e. 

A suspension of incompressible solids at a concentration of 300 kg m of slurry is to be filtered at constant pressure drop. Estimate the filtration area necessary to produce 50kgh of dry solids.
