note = {The basic analytical methods for expression, the separation of liquid from solid-liquid systems by compression, are presented from the viewpoint of the flow through compressible porous media. The mathematical models of the Terzaghi model, the Terzaghi-Voigt combined model and a simplified semi-theoretical equation are summarized. On the basis of the theory, constant-pressure expression of both semisolid materials and slurries, and two-dimensional expression on a tubular filter element, are discussed. It is also shown that the constant-rate expression process is well described from calculations based upon constant-pressure expression data. Internal mechanisms of settling sediments are mathematically analysed on the basis of consolidation theory, and the basic differential equations for settling of concentrated suspensions are presented. The hydraulic expression phenomenon in ordinary filter press operation, which depends on a change in filtrate flow pattern, is also described and analyzed.},
