Resumen
Flocculation is one of the priority processes for the purification of water; which, being
ineffective, results in lower quality drinking water for downstream treatment processes,
decreasing the quality of the treated water and increasing operating costs. The objective of
this study was to evaluate the hydraulic efficiency of a horizontal flow screen flocculator in
the water treatment plant of the “Bayas-Azogues”. To do this, first the geometric
characteristics of the three zones of the flocculator were measured. Subsequently, the salt
tracer test was performed for the three study flows (6.78, 7.84 and 8.59 l/s). To systematically
predict the real behavior of the flocculator, the Hec-RAS (one-dimensional) and IBER (twodimensional) mathematical models were used. The main results are divided into a first phase
of the study that consisted in obtaining and comparing the experimental and analytical
hydrodynamic factors that determine the operation of this reactor. The second phase
consisted of the study and comparison of the hydraulic results obtained from the models
(Hec-RAS and IBER). As conclusions, the flocculator works predominantly in piston flow,
with the presence of dead zones in a higher percentage in zone 3 of it. From the results of the
IBER model (two-dimensional), it was determined that, in the corners of the flocculator, that
is, where changes in direction occur, there are areas of stagnation due to the very low speeds
reached in those sections.
