Estudo da atividade metanogênica específica de diferentes lodos anaeróbios

Abstract: RESUMO O estudo da atividade metanogênica específica (AME) constitui uma importante ferramenta para o controle operacional de reatores anaeróbios, pois apresenta parâmetros de monitoramento da eficiência e estabilidade de um reator biológico. Nesse sentido, o presente trabalho visou determinar a AME de lodos provenientes de reatores anaeróbios de fluxo ascendente (UASB - upflow anaerobic slugde blanket) de duas indústrias cervejeiras (lodos A e B), uma de processamento de grãos (lodo C), uma leiteira (lodo D) … Show more

“…The specific methanogenic activity (SMA) is a key for assessing the methane producing ability of sludge for a particular substrate, where substrate availability is not limiting [ 29 ]. Determining the SMA during the reactor start-up phase helps to establish the appropriate initial organic loading rate, while monitoring it throughout various stages provides insights into sludge development [ 30 ]. In this study, the SMA was measured before reactor start-up, after phase I, and after phase III.…”

“…De este modo se puede determinar que en la mayoría de los casos la generación de biometano está alrededor de 350L/kgSV, con un 70% aproximadamente de metano (Lorenzo et al, 2005). Otros estudios muestran valores diferentes atribuidos a las propiedades de la materia prima biodegradada (Leturia et al, 2015), condiciones de la biodigestión (Farid et al, 2019), o el tipo de inóculo empleado (Longaretti et al, 2019).…”
