Generación de lodos y evolución de la biomasa de un reactor UASB a escala real tratando efluente de maltería
The change of an old Imhoff tank into an UASB reactor to treat brewery effluent was carried out based on the results of a pilot‐scale test, and a technical and economic feasibility study. The reactor was inoculated with sludge from an anaerobic treatment pond for meat packing plant effluents, which adapted easily and caused no inconveniences related to its original grease contents. The complete load was achieved in just nine weeks, with a soluble COD removal of approximately 80%. The evolution of the sludge blanket was monitored, including the determination of total and volatile solids content, and the profiles of the solids concentrations at different heights in the whole reactor. The original sludge immediately formed small granules with an average size of 0.7 to 0.85 mm. The loads around 0.2 kg COD/kg VSS.d achieved at the start‐up were relatively low, due to the high amount of a totally expanded sludge, with concentrations between 40 and 50 g TSS/L and 85% of VSS. A value of Y = 0.09 g VSS/g CODrem was obtained for the cellular yield coefficient.

Luego de una experiencia a escala piloto y de un estudio de factibilidad técnico-económica se llevó a cabo la transformación de un viejo tanque Imhoff en reactor UASB para tratar efluente de maltería. El reactor se inoculó con lodo proveniente de una laguna anaerobia de tratamiento de efluente de frigorífico que se aclimató sin problemas ni presentó inconvenientes asociados al contenido graso original. Se alcanzó la carga completa en tan solo nueve semanas, con una remoción en el entorno del 80% de la DQO soluble. Se siguió la evolución de la manta de lodos, incluyendo la determinación del contenido de sólidos totales y volátiles en todo el reactor y los perfiles de concentración de sólidos a distintas alturas. El lodo original formó pronto gránulos pequeños con un tamaño medio de 0.7 a 0.85mm. Las cargas en el entorno de 0.2 kgDQO/(kgSSV.d) que se alcanzaron en el arranque son relativamente bajas debido a la alta cantidad de lodo, que se encuentra totalmente expandido, con concentraciones entre 40 y 55 gSST/L y 85% de SSV. Se obtuvo un valor de Y = 0.09 gSSV/gDQOrem para el coeficiente de rendimiento celular.
