Further development of software for the design and simulation of industrial thickeners

In the present work, the software is extended to thickeners having conical bottoms. As model functions, two choices are possible, a solid flux density function for the whole range of solid concentrations or a solid flux density function for concentrations less than the critical and a sediment permeability and an effective solid stress for concentration above the critical. The following outputs can be chosen, the unit area, the cross-sectional area for a given capacity and height of sediment, the plot of sediment height versus thickener area for a given capacity, the plot of sediment height versus capacity for a given thickener area and the concentration profiles and mass balances for any of these cases.
