The efficiency of biological wastewater treatment systems is linked fundamentally to the hydraulic performance of each treatment unit. These units should guarantee an adequate contact between the microorganisms and the residual water, and the compliance with the hydraulic retention time established, in order to decrease the number of dead zones or short circuits that may exist inside the reactors. In this work, hydraulic performance was evaluated in seven Expanded Granular Sludge Bed (EGSB) reactors with a useful volume of 3,4 L and constructed in acrylic. The analysis was carried out through the stimulus-response test, using bromide as tracer. Two hydraulic retention times (8 and 24 h) and the effect of the presence of granular biomass were considered. Results were analyzed qualitatively through the construction of curves C, E and F, and quantitatively through the construction of a mathematical model of axial dispersion. The results of the hydraulic performance of the reactors revealed a marked tendency to a complete mix flow pattern, with a low effect of HRT or the presence of granular biomass on their operation.
La eficiencia de los sistemas biológicos de tratamiento de aguas residuales está vinculada fundamentalmente al rendimiento hidráulico de cada unidad de tratamiento. Estas unidades deben garantizar un contacto adecuado entre los microorganismos y el agua residual, y el cumplimiento del tiempo de retención hidráulico establecido, con el fin de disminuir el número de zonas muertas o cortocircuitos que puedan existir dentro de los reactores. En este trabajo, se evaluó el rendimiento hidráulico de siete reactores EGSB (del inglés Expanded Granular Sludge Bed ) con un volumen útil de 3,4 L y construido en acrílico. El análisis se llevó a cabo a través de la prueba de estímulo respuesta, utilizando bromuro como indicador. Se consideraron dos tiempos de retención hidráulica (8 y 24 h) y el efecto de la presencia de biomasa granular. Los resultados se analizaron de forma cualitativa a través de la construcción de las curvas C, E y F, y cuantitativamente a través de la construcción de un modelo matemático de dispersión axial. Los resultados del desempeño hidráulico de los reactores revelaron una marcada tendencia a un patrón de flujo de mezcla completo, con un bajo efecto en su operación por parte de la TRH o la presencia de biomasa granular.
