Wave Propagation Phenomena in the Theory of Sedimentation

Mathematical theory of gravitational solid-liquid separation processes

  • Chapter
Numerical Methods for Wave Propagation

Part of the book series: Fluid Mechanics and Its Applications ((FMIA,volume 47))

Abstract

Sedimentation processes are employed in a variety of industrial applications in which a suspension, a mixture of a fluid and fine solid particles, is separated into its solid and liquid components under the influence of gravity. In the mining industry, large vessels, so-called thickeners of up to 100 m in diameter and 6 m in depth with a slightly conical bottom, are used for the settling of the suspension and for the consolidation of the sediment. In a continuous thickener, the control operations (feeding of fresh suspension, discharge of the concentrated sediment at the bottom and overflow of the supernatant clear liquid) take place continuously. Fig. 1 shows a schematic cross-section of a continuous thickener [14].
