Simulation of the secondary settling process with reliable numerical methods
A consistent model for the settling-compression-dispersion process in the secondary settling tank (SST) can be expressed as a partial differential equation (PDE). Reliable numerical methods for simulation produce approximate solutions that converge to the physically relevant solution of the PDE as the discretization is refined. We focus on two methods and assess their performance via simulations for two scenarios. One method is provably convergent and is used as a reference method. The other method is less efficient in reducing numerical errors, but faster and more easily implemented.
