Abstract
Cake filtration has a variety of applications in wastewater treatment by solid/liquid separation processes. In order to obtain the physical
properties of the filter cake, a Compression–Permeability Cell (C–P Cell) can be used to examine the constitutive relationships among the
solid compressive stresses, porosity and the specific filtration resistance. In this paper, a mathematical model is proposed to study the transient
distribution of stresses, strains and void ratios in the confined cake of a C–P Cell under constant axial loads for dewatering. Simulations have
been carried out using a plasticity model and the sensitivity analysis has revealed the possible contribution a finite plasticity can bring about
the two types of cake examples with either medium or high compressibility.
