The Role of pdin the Unified Theory on Solid-Liquid Separation: Especially on the Cake Thickness at Hindered Sedimentation, Cake Filtration and Expression

To know the role of `the solid compressive pressure to the first solid layer of a cake, ` in the `unified theory on solid-liquid separation`, we analyzed extremely compressible cake formed with floc for the following three operations with our new concepts. First, the role of was studied in calculating the sediment thickness of floc, and in calculating the cake thickness in cake filtration performed with floc sediment. Second, we calculated the expression procedure using . Finally, the influence of on cake thickness in hindered sedimentation, and on the calculation of the procedure of hindered sedimentation was verified. Thus the possibility of application of `unified theory on solid-liquid separation` and the importance of was verified. Through these processes, new theoretical definitions of the cake filtration, expression and hindered sedimentation was established.
