In this study, the internal phenomena that occur during cake filtration, expression and hindered sedimentation were calculated and experimented using the ‘unified theory on solid-liquid separation’ with new boundary conditions. The expression procedure, the variation of pressure distribution in a compressible and incompressible cake were calculated. The procedure of hindered sedimentation was calculated with the new boundary conditions from ‘unified theory on solidliquid separation’ and experiments against various concentration.
