Abstract

This study presents a mathematical model examining wastewater pollutant removal
through an oxidation pond treatment system. This model was developed to describe
the reaction between microbe-based product mPHO (comprising Phototrophic bac-
teria (PSB)), dissolved oxygen (DO) and pollutant namely chemical oxygen demand
(COD). It consists of coupled advection-diusion-reaction equations for the microor-
ganism (PSB), DO and pollutant (COD) concentrations, respectively. The coupling
of these equations occurred due to the reactions between PSB, DO and COD to pro-
duce harmless compounds. Since the model is nonlinear partial dierential equations
(PDEs), coupled, and dynamic, computational algorithm with a specic numerical
method, which is implicit Crank-Nicolson method, was employed to simulate the dy-
namical behaviour of the system. Furthermore, numerical results revealed that the
proposed model demonstrated high accuracy when compared to the experimental data.

Keywords Oxidation pond; nonlinear PDEs; PSB; implicit Crank-Nicolson.
