✦ Synopsis

An analysis of the viscous flow of time-independent non-Newtonian fluids in anisotropic compressible porous media has been conducted and applied to the problem of filtration of slurries in which the filtrate is non-Newtonian. The fundamental relationship formulated for filtration, which incorporates recent modifications of Tiller and Shirato, accounting for variations of the superficial velocity of the liquid and of the particles of the cake, associated with cake compaction, has been utilized in the analysis of constant pressure filtration. The efficacy of the concepts and relationships developed for constant pressure filtration in the interpretation and processing of experimental data is demonstrated with data collected in the constant oressure filtration of slurries of calcium carbonate in hydroxyethyl cellulose (Natrosol-25OG) solutions. 1NTRODUCTION 3'.
