Abstract : Water crisis is one of the major issues that the world is facing today. The available water is to be treated as a solution to the issue. The treatment that determines the water quality involves very important chemical process and is to be controlled. In this work, a mathematical model for the water treatment plants is developed so that new control methods can be applied to obtain effluent water of required standards. The major challenge in modelling water treatment processes is to establish the nonlinear relationships between the inputs and outputs of each process. This work presents a model based on the principle of material balance and simulation, for a water treatment system that consisting of rapid mixing system and a flocculation system ahead of the sedimentation tank. The developed model gives the dependencies of the pH and turbidity of treated water to the chemicals added. Simulation is performed to draw the effect of coagulant dosage on pH, surface charge and turbidity. The relationship between raw water alkalinity, coagulant flow and turbidity of effluent water is also simulated. This work further investigates the effectiveness of various configurations of Hammerstein-Wiener model for the water treatment system, to choose the best configuration. This chosen model can be suggested for resolving the problem of optimal coagulant dosing thereby resulting in cost reduction and improving water quality through automatic coagulant dosage rate control.
