Abstract
The treatment efficiency of waste stabilization pond is directly related to its hydraulic regime. The
hydraulic efficiency of the pond is dependent on parameters such as the pond geometry, the location of
inlet and outlet and the inlet flow velocity. Poorly designed or specified hydraulic parameters may lead
to short circuiting and dead regions within the pond. This in turn impacts the dispersion coefficient.
Drogue and tracer studies are often used to get actual dispersion coefficients; however, tracer studies
can be costly and are therefore not practical to do frequently. The objective of this paper is to obtain the
actual dispersion coefficient using computational fluid dynamic (CFD) approach (using Fluent). The
CFD results are validated using an actual tracer test.
