Given the average, maximum e peak influent flows to the reactor and its basic geometric charateristics, calculates the volumetric hydraulic loads, the hydraulic detention times, the superficial velocities, the velocities in the acess to the settling compartments, the superficial loading rates and the detention times in these chambers and the influence area of each distribution pipe, allowing to compare these values with prof. Chernicharo recommendations.
