Simulate the Effect of Configuration and Number of Baffles in the Hydraulic Efficiency of Chlorine Contact Tanks

Chlorine contact tanks are commonly used to disinfect drinking water before distribution. These tanks are usually open compartments that are divided by a series of baffles. The separation of the compartments helps to control the flow of water through the tanks and improves the process of disinfection of the chlorine. The main purpose of chlorine contact tanks provides a suitable residence time for both micro-organisms and disinfectants to achieve the desired degree of inactive germs (Angeloudis, 2014).In this study, the simulation of the 3D model of the CT-1 contact memory model using the ComsolMultiphysics 5.3a software is presented. The experimental model of this tank is located at the Hyder Lab of the Water and Environmental Research Center at Cardiff University of England (Fig. 1) (Angeloudis, 2014).
