The CFD study of mechanical circulators for water treatment is a computational fluid dynamics analysis that simulates and optimizes flow, mixing and oxygenation in effluent tanks and lagoons. This technology makes it possible to predict the behavior of fluids before physical installation, ensuring maximum energy and operational efficiency of the agitation system, avoiding rework and unnecessary costs in the plant.
In water treatment plants (ETA) and sewage treatment plants (ETE), adequate homogenization is vital for the success of chemical and biological reactions. Using cutting-edge software, we design the ideal positioning and geometry of the Mechanical Circulator Agitators blades. Although AGIMIX mechanical circulators were developed to optimize the sugar cooking process, their mechanical robustness and high mass movement capacity make them perfectly adaptable to the density and requirements of industrial and municipal effluent treatment.
Agimix has been in the industrial agitation and mixing solutions market for 15 years, supplying agitators, tanks, reactors, mixers, dispersers and related equipment, serving the industry in general with excellence. For the sanitation sector, which uses reservoirs of gigantic proportions, we highlight that we exclusively supply the complete circulation and agitation system, custom-designed to be installed directly in the concrete tank or geomembrane that the customer already has in their infrastructure.
Investing in an agitation project with CFD simulation eliminates dead zones at the bottom of the tanks and prevents unwanted decantation of suspended solids. Our engineers analyze current lines, shear rate and gas dispersion, delivering industrial mixing equipment that reduces electrical energy consumption and significantly increases the oxygen transfer rate in activated sludge, optimizing the entire treatment cycle.
The simulation guarantees complete movement of the fluid, avoiding the accumulation of sludge at the bottom and improving the homogenization of effluents.
The optimized positioning of the Mechanical Circulator Agitators increases the oxygen transfer rate to microorganisms.
The fluid dynamic study scales the exact power of the engine, avoiding electrical waste in continuous treatment operations.
Hydrodynamic force analysis protects the circulator shaft and propellers against excessive vibrations and premature wear.
Each water treatment CFD simulation is adapted to the customer's specific tank geometry, ensuring accurate and reliable results.

Direct answers to the most common questions about this equipment and its application.
The CFD (Computational Fluid Dynamics) study is a virtual simulation that analyzes how water and effluents behave under the action of an agitator. This technology allows the flow, speed and dispersion of particles to be visualized before the equipment is manufactured. With this, we guarantee the perfect sizing of the mixing system for your plant.
Simulation is crucial because it prevents the formation of dead zones and decantation of solids in large tanks. By predicting hydrodynamic behavior, the study ensures that microorganisms receive oxygen and nutrients homogeneously. This results in a much faster, more stable and efficient biological treatment.
No, Agimix exclusively supplies the circulation and agitation system for these large-scale projects. Our equipment is custom designed to be installed in basins, lagoons or concrete tanks that the customer already has in their treatment plant.
The Mechanical Circulator Agitators works by moving large masses of liquid from the surface to the bottom, and vice versa. This strong circulation current increases the contact time of air bubbles with the effluent, maximizing the transfer of dissolved oxygen necessary for aerobic bacteria.
No, although AGIMIX mechanical circulators were originally developed to optimize the sugar cooking process, their robust engineering is highly adaptable. Through CFD-validated rotation and blade profile adjustments, they offer excellent performance in the homogenization of dense effluents and activated sludge.
The study mainly optimizes the fluid velocity profile, engine power consumption and shear rate. We also evaluate the ideal positioning of the equipment within the basin to ensure that the entire liquid mass is moved with the lowest possible energy expenditure and without causing structural damage.
Time varies depending on the complexity of the tank geometry and fluid properties, but typically a CFD simulation project takes two to four weeks. This deadline includes 3D modeling, processing mathematical calculations in specialized software and issuing a detailed technical report.
Yes, reducing electrical consumption is one of the biggest benefits of fluid dynamic analysis. By identifying the exact angle of the blades and the ideal rotation, we avoid oversizing the engine, ensuring that the plant uses only the energy strictly necessary to keep the sludge suspended and oxygenated.
