“…Although there has been extensive work on the production of VFAs from waste streams [19], the process cannot easily be scaled up to industrial level due to challenges faced during the recovery of VFAs from the system [10]. The recovery of VFAs from the bioreactor is crucial to the downstream processing, and production stability and efficiency [20]. Due to the complex physiochemical nature of the fermentation broth and low concentration of acids in the system, separating the VFAs from the fermentation broth is a challenging task [21].…”

“…This ease of continuous operation guarantees higher productivity rates [26]. Moreover, solid retention time can be controlled independently from hydraulic retention time [20]. Additionally, as the feeding and removal of metabolites can be controlled, metabolites of a specific stage of bioconversion can be removed from the bioreactor to suppress substrate or product inhibition.…”

The significant amount of excess sewage sludge (ESS) generated on a daily basis by wastewater treatment plants (WWTPs) is mainly subjected to biogas production, as for other organic waste streams such as food waste slurry (FWS). However, these organic wastes can be further valorized by production of volatile fatty acids (VFAs) that have various applications such as the application as an external carbon source for the denitrification stage at a WWTP. In this study, an immersed membrane bioreactor set-up was proposed for the stable production and in situ recovery of clarified VFAs from ESS and FWS. The VFAs yields from ESS and FWS reached 0.38 and 0.34 gVFA/gVSadded, respectively, during a three-month operation period without pH control. The average flux during the stable VFAs production phase with the ESS was 5.53 L/m2/h while 16.18 L/m2/h was attained with FWS. Moreover, minimal flux deterioration was observed even during operation at maximum suspended solids concentration of 32 g/L, implying that the membrane bioreactors could potentially guarantee the required volumetric productivities. In addition, the techno-economic assessment of retrofitting the membrane-assisted VFAs production process in an actual WWTP estimated savings of up to 140 €/h for replacing 300 kg/h of methanol with VFAs.

“…Un estudio realizado por Cardeña R et al [33], indican que producciones altas de ácidos volátiles inhiben la producción de hidrógeno, estos autores observaron valores de producción de hidrógeno entre 77 y 87% y valores de AVT entre 21 y 51%, por lo que concluyeron que valores bajos de AVT contribuyen al alto rendimiento en la producción de hidrógeno. Esta misma observación la indican autores como Trad Z et al [34]. Por lo cual, regular la producción de AVT en los reactores anaerobios utilizados para producción de hidrógeno puede ser un indicador para mejorar la estabilidad y rendimiento.…”

ResumenEl objetivo de este estudio es comparar la producción de hidrógeno en un reactor de biomasa fi ja y de manto de lodos y fl ujo ascendente (Hybrid UASB). Se utilizó neumático triturado y anillos de Biopack como material de soporte. Los reactores fueron operados por 35 días con un tiempo de detención hidráulica de 12h y una carga orgánica volumétrica de 11,26gDQO/L.d, usando sacarosa como fuente de carbono. La producción porcentual promedio de hidrógeno fue de 45 y 48% para el reactor de biomasa fi ja y el reactor UASB-Híbrido, respectivamente. Con base en los resultados y análisis estadístico, se determinó que la confi guración del reactor no infl uye en la producción de H 2 . Adicional a lo anterior, se observó estabilidad en el proceso. Palabras clave: ácidos volátiles totales, conversión de la sacarosa, energía renovable, fermentación natural. AbstractThe aim of this study is to compare the hydrogen production on a packed-bed reactor and upfl ow anaerobic sludge blanket (Hybrid UASB). Crumb rubber (recycled tires) and Biopack rings were used as a support matrix. The reactors were operated for 35 days with hydraulic retention time of 12h and an organic volumetric load of 11.26gCOD/L.d, using sucrose as carbon source. The average hydrogen production was 45 and 48% for packed-bed reactor and Hybrid-UASB, respectively. Based on the results and the statically analysis, it was determined that the confi guration of the reactor does not infl uence on the hydrogen production. Moreover, it was observed stability of the process.
