Simple mass balance controllers for continuous sedimentation
The rational use of water in the mineral processing industry has become an im-portant issue due to the geographical location of many plants. The increase of capacity in manycopper concentrators has lead to an increased effort for recovering the maximum amount ofwater in the solid-liquid separation process. Thickeners work continuously to produce a con-centrated underflow and a w...
متن کاملStatistical theory of sedimentation of disordered suspensions.
An analytical treatment for the sedimentation rate of disordered suspensions is presented in the context of a resistance problem. From the calculation it is confirmed that the lubrication effect is important in contrast to the suggestion by Brady and Durlofsky (Phys.Fluids 31, 717 (1988)). The calculated sedimentation rate agrees well with the experimental results in all range of the volume fra...
متن کاملMultidimensional coupled sedimentation and consolidation theory
Modelling of the sedimentation and consolidation processes requires specialized software and unified theories. This paper discusses the numerical modeling of coupled sedimentation and large strain consolidation. Using the two-phase flow theory, it is possible to unify the theories of sedimentation and consolidation with consistent variables and coordinates, and the one-dimensional unified gover...
متن کاملOperating charts for continuous sedimentation II: step responses
Abstract. The process of continuous sedimentation of particles in a liquid has often been predicted by means of operating charts and mass-balance considerations, where the underlying constitutive assumption is the one by Kynch. Much more complex operating charts (concentration-flux diagrams) can be obtained from a onedimensional model of an ideal continuous clarifier-thickener unit. The enginee...
متن کاملDynamic and Steady-State Behavior of Continuous Sedimentation
Continuous sedimentation of solid particles in a liquid takes place in a clarifierthickener unit, which has one feed inlet and two outlets. The process can be modeled by a nonlinear scalar conservation law with point source and discontinuous flux function. This paper presents existence and uniqueness results in the case of varying cross-sectional area and a complete classification of the steady...
