This is a FLOW-3D HYDRO simulation of a circular contact tank with concentric baffles. A scalar is introduced at the inlet in the center and we can see the dispersion as the flow travels through the tank, with the fluid colored to show the percentage of scalar present. The graph on the lower left corner is giving us the percentage of scalar at the outlet pipe, also known as a residence time distribution (RTD) curve. This information can be useful to understand and improve contact tanks designs: making sure there is optimal mixing, no dead zones and no short circuiting. Down the line, improving efficiency helps save on operational costs. Learn more about FLOW-3D HYDRO's water treatment modeling capabilities at flow3d.com/products/flow-3d-hydro/water-treatment/.
