dc.descriptionIn this research was evaluated the degradation of activated sludges from a brewing industry located in Zulia State (Venezuela) under mesophilic condition (MC) to 37º C and termophilic condition (TC) to 55º C throughout the use of an anaerobic digester of suspended growth and complete mixture of 3.5 L, that worked with discontinuous flow. Hydraulic retention times (HRT) of 30, 25 and 15 days were evaluated. The highest removals were obtained by applying the volumetric organic load (VOL) of 1 kg COD m3 /d (30-day HRT), where 32% of the CODtotal were removed, 10% of total solids (TS) and 29% of the volatile solids (VS) for the MC and 59%, 32% and 43% for CODtotal, ST and SV respectively in the TC. The methane concentration in biogas was around 60% for both conditions, and the volatile fatty acid concentration (VFA) stayed always smaller than 35 mg/L indicating that all the acidified COD was transformed to methane.en-US
dc.descriptionEn esta investigación, se evaluó la degradación de lodos activados provenientes de una industria cervecera ubicada en el Estado Zulia (Venezuela) bajo condiciones mesofílicas (CM), a 37º C y condiciones termofílicas (CT), a 55º C mediante el uso de un digestor anaerobio de crecimiento suspendido y mezcla completa de 3,5 L, que trabajó con flujo discontinuo. Se evaluaron tiempos de retención hidráulicos (TRH), de 30, 25 y 15 días. Las mayores remociones se obtuvieron al aplicar la carga orgánica volumétrica (COV), de 1 kg DQO m3 /d (TRH de 30 días), en la cual se removió el 32% de la DQOtotal, 10% de sólidos totales (ST), y 29% de sólidos volátiles (SV), para la CM y 59%, 32% y 43% para DQOtotal, ST y SV respectivamente en la CT. La concentración de metano en el biogás estuvo cerca al 60% para ambas condiciones, y la concentración de ácidos grasos volátiles (AGV) se mantuvo siempre menor a 35 mg/L, indicando que toda la DQO acidificada fue transformada a metano.es-ES
