MULTI-STEP EULERIAN METHOD FOR MULTICOMPONENT TRANSPORT IN WATER NETWORKS

ABSTRACT The contamination within the distribution system can be protected through the maintenance of specified residual chlorine. The organic matter and bacterial content present in the water govern the concentration of residual chlorine levels. Interactive behavior of these substances can be represented through well-defined processes represented through set of differential equations and are solved using multi-step Eulerian computational scheme. The application of the model is illustrated for a real life distribution network. The chlorine concentrations are found to be dependent on the substrate content, and wall reaction parameter. For the network studied, it is observed that more the substrate higher is the biomass growth resulting in lower chlorine concentrations. The model presented in this paper is of immense help to thec water supply authorities.
