Abstract (EN): In this work it is shown that, using a simple technique it is possible to simulate in detail the dynamics of a shallow-layer gravity settler. Although a promising approach based on the population balance equation has been proposed long ago (Ruiz, 1985), currently acknowledged models for the shallow-layer gravity settler apply only to specific equipments at steady state and laboratory scale, Hartland and Jeelani (1994), Rommel et al. (1992). To our knowledge, no study has ever addressed the dynamic simulation of a gravity settler. In this paper a direct numerical technique is presented for computing the thickness and drop-size composition of the dispersion band formed in a shallow-layer settler under steady-state and transient conditions. This technique is an extension for the settler of the one used on the stirred vessel by Ribeiro (1995). The drop interaction model used is the one proposed by Ruiz (1985). Imperfections were detected in Ruiz’s model and a possible alternative is suggested.
