In Section 2, we briefly summarize the model describing the settling behaviour of a flocculated suspension in a continuous thickener, which results in the initial–boundary value problem mentioned above. In Section 3we present numerical examples for transient batch and continuous sedimentation processes, and in Section 4, we discuss these results.

Theory and Application of Thickener Design

Continuous sedimentation has an important role in coal preparation plants for clarifying and recycling the process water and reducing thevolume offine refuse for subsequent mechanical dewatering ordisposal. Thesolids flux curve is used to model the process of continuous sedimentation. It is employed mainly in

The first simple but complete model describing the settling of a monodisperse suspension of small rigid spheres is the kinematic sedimentation model due to Kynch, which leads to a scalar nonlinear conservation law. The extension of this model to flocculated suspensions, pressure filters, polydisperse suspensions and continuously operated ...

In spite of the fact that the phenomenological theory of sedimentation is widely accepted, only steady state solutions have been discussed and used for thickener design, as reviewed by Concha and Barrientos (1993). In this work, we present a transient solution to batch and continuous sedimentation of flocculated suspensions.

Sedimentation of a suspension of small particles dispersed in a viscous fluid can be described by a scalar, nonlinear conservation law, whose flux function usually has one inflection point. The identification of the flux function is of theoretical interest and practical importance for plant-scale simulators of continuous sedimentation.
