This article provides a state-of-the-art review on the different turbulence and multiphase
models for the sedimentation tank studies of both water treatment plant (WTP) and …

The recent progress in numerical modelling techniques applied to sedimentation tanks in
wastewater treatment is reviewed to determine their usefulness. The models reviewed range …

A numerical model for the computation of turbulent flows in sedimentation tanks is
presented. Based on a nonorthogonal grid formulation, it can handle fairly arbitrary two …

A mathematical model for predicting the velocity field and suspended solids transport in
secondary rectangular settling tanks is presented. The model is applied to investigate the …

Numerical results from a computer model for the prediction of the neutrally buoyant flow
within sewage treatment plant settling basins are compared with results of several new …

A numerical model is presented for simulating the flow and the settling performance of
primary clarifiers. The model consists of 2 parts: a flow model providing the velocity and …

In this study, the effect of different numbers of baffles is investigated using computational
simulation. Laboratory measurements using different numbers of constant height baffles in a …

The numerical simulation of the disinfection processes in a contact tank involves
determining both the flow and solute transport distributions. In this study it has been …

A numerical model for an idealized circular tank with no baffle is used to investigate the
relative importance of inlet solids concentration and inlet flow on the removal of solids field …

Circulation regions always exist in the settling tanks. These regions reduce the tank's
performance and decrease effective volume of the tank. Recirculation zones would also …
