One of the ways to determine the best geometry is by evaluating the uniformity of energy dissipation rate. Since energy dissipation rate is the core parameter that influence the particle collision, flocculation tank with uniform energy dissipation rate will perform better. We investigated different geometric space to come out with a flocculation tank with uniform energy dissipation rate. The optimization method started with an initial condition. We then changed the geometry parameters such as clearance height, baffle spacing and flocculation tank height. If change in geometry resulted in a more uniform energy dissipation rate than the initial geometry, the new geometry is called incumbent. Following this process, investigate the geometry in all possible geometric space and the final incumbent will be chosen as the optimal solution.
