Numerical modelling of sedimentation processes

This paper considers the well-documented theory for the design of sedimenta tion tanks. The difference in this treatment is that a numerical model is u sed to do the necessary calculations for the limiting flux and the equation s to do this are put in a dimensionless format. The model for a cylindrical settler is extended to the case of a conical settling geometry. It is show n that the conical settler can handle a wider range of solids loading. Fina lly, calculations are reported to estimate the characteristics of batch set tling experiments for conical settlers and the results are compared with ex perimental data.
