Abstract
This current research used HPAs model for sedimentation process and HPAd model for disinfection process to make formulation of mathematical model of flow velocity, NFr and Nre patterns and to analyze the effect of hydrodynamic to contaminant. Transport mechanism in pollutant dispersion was analogized to pollutant transport phenomenon in river. This research aims to study mathematical models of velocity, NRe, NFr, E.coli distribution and residual chlorine patterns in baffle channel disinfection tanks based on the hydrodynamic model (HPAd Model) mathematical formulation and the suspended particles and turbidity in sedimentation tank based on the hydrodynamic model (HPAs Model). Research includes the formulation of mathematical models which results have been visualized by Mathlab, the acquisition of primary data using physical models, testing the model using Mathlab with the primary data input. The parameters flow velocity pattern (u), Reynolds numbers (NRe) and Froude numbers (NFr), but E.coli distribution and residual chlorine didn’t influenced the pattern flow velocity and Froude Number. However, pattern flow had influenced turbidity and settling floc sedimentation. Dosage and type of disinfectant and coagulant influenced the pattern of Reynold Number due to effect of acceleration and dragging flow correlated to dispersibility.
