Abstract:
A numerical flow analysis for the design of an oxidation pond was conducted to investigate the optimal flow characteristics. This analysis includes the inflow rate and the shape and depth of the oxidation pond. The total area and maximum depth of the pond were 500 m(2) and 3 m, respectively. We defined the retention time, retention time ratio, homogeneity index, and inflow exchange efficiency in order to choose the optimal conditions. The optimum width to length ratio and depth of the pond were found to be 1:5 and 2 m, respectively.
