Modeling and Simulation of a Vertical Hydraulic Flocculator for a Drinking Water Treatment Plant

Objective: The aim of this study is to perform the mathematical simulation of a vertical hydraulic flocculator designed for the Vista Bella water treatment plant in Morelia, Michoacán, with the goal of replacing the mechanical flocculation system. Theoretical Framework: Conventional surface raw water treatment is suitable for waters with high turbidity. This process involves several stages such as coagulation, flocculation, sedimentation, filtration, and disinfection, for subsequent distribution to the population. Flocculation is the mechanism by which suspended solids aggregate to form flocs, and these larger and heavier particles can be sedimented. Method: The methodology adopted for this research included developing and analyzing the model and performing numerical simulation to validate the analytical results obtained in the design of a vertical hydraulic flocculator. Results and Discussion: The results demonstrate the feasibility of constructing the hydraulic flocculator to replace the current mechanical system, which involves high operational and energy costs at the plant. Implications of the research: The findings of this study are important for the development of hydraulic flocculators in water treatment facilities, both for designing new units and for adjusting existing ones, given the limited available information on the subject. Originality/Value: This study presents a methodology for flow analysis in hydraulic flocculator tanks to facilitate the transition from mechanical to hydraulic flocculators, reducing the environmental impact caused by motor energy consumption.
