“…For Avicel, the hydrolysis rate constant was determined to be 0.36 d -1 . This was consistent with other studies using the same ISR for the digestion of glucose-based substrates that rapidly degrade like Avicel (Raposo et al 2011). Compared with the rate constants reported in studies where lignocellulosic substrates were digested, the investigated DS has distinct advantages.…”

“…The level of biodegradability is expressed as the ratio between the experimental methane yield (BMPExp) and its theoretical value (BMPTh Buswell), which can be calculated from the elemental composition of the sample (Raposo et al 2011). The contents of carbon (C), hydrogen (H), nitrogen (N), and sulfur (S) of the investigated DS samples were determined via elemental analysis.…”

Based on the results of this study, a total energy amount of 3,111 TJ/year can be produced from the anaerobic digestion of deinking sludge (DS) arising from German deinked pulp mills, which can then be used to replace up to 5% of the total energy demand for those mills. The DS examined was generated by flotation deinking at the laboratory scale from selected mixes of paper for recycling (PfR). The results from the batch fermentation tests indicated a strong dependence of the methane potential of the DS on the carbohydrates and lignin contents, which in turn are linked to the original PfR quality. The highest methane yield was observed for DS100 (25.8% carbohydrates; 5.1% lignin) with 280.4 mL/g of volatile solids (VS) added, while DS70 (14.2% carbohydrates; 24.9% lignin) showed the lowest methane yield, with 122.1 mL/gVS. All of the DS samples showed high methane production rates, in the range between 59.4 (DS70) and 118.6 mL/gVS d -1 (DS100), and kinetic constants of 0.66 to 0.79 d -1 . Additionally, no distinguishable lag phases were observed, which strongly indicates the rapid biodegradation of the DS.

Pretreatment of thickened waste activated sludge (TWAS) with high pressure thermal hydrolysis (HPTH) prior to codigestion with primary sludge (PS) in two-stage anaerobic digestion was evaluated at two systems hydraulic residence times (HRTs). Pretreatment increased the soluble COD (SCOD) entering the acidogenic digester and at a 2 day HRT the increase in SCOD through the digester was also enhanced. With a 1 day HRT in the acidogenic digester the increment in SCOD concentrations was smaller in the pretreated reactor than in the control reactor suggesting there is a minimum residence time required to maintain hydrolysis of pretreated TWAS. At the 2 day HRT fermentation to volatile fatty acids (VFA) was similar in both reactors despite the considerably higher SCOD concentrations in the pretreated sludge. In contrast, at the 1 day HRT the pretreated digester VFA concentrations were 36% higher than that of the control digester. The control and pretreated methanogenic digesters operating at an HRT of 13 days had average total COD (TCOD) removal efficiencies of 45 and 52%, respectively which was consistent with an increase in methane yield from 0.19 L CH 4 /g COD for the control system to 0.23 L CH 4 /g COD for the pretreated system. With an HRT of 9 days, the corresponding TCOD removal efficiencies were reduced to 43% in and 48% respectively and the methane yields were 0.14 and 0.16 L CH 4 /g COD, respectively. COD removal to methane was found to be not significantly different between the control and pretreated systems at the reduced HRT.

“…La composición y la concentración del sustrato pueden ocasionar fenómenos de inhibición que influyen sobre el metabolismo de los microorganismos y por lo tanto afectan la cantidad de CH 4 generado. Por esta razón, se deben caracterizar previo al ensayo, tanto en términos de parámetros fisicoquímicos como de su composición elemental [7,16]. Dependiendo del tipo de sustrato, puede requerirse un pretratamiento.…”

ResumenLa digestión anaerobia es un proceso biológico que permite lograr dos propósitos de manera simultánea, el tratamiento de residuos para el control de la contaminación ambiental y el aprovechamiento y valorización de los subproductos generados: el metano como fuente de energía renovable y el material digerido con potencial de aplicación agrícola. Con el fi n de determinar la capacidad de producción de metano, la biodegradabilidad anaerobia de un sustrato orgánico, seleccionar sustratos e inóculos potenciales y predecir el funcionamiento de digestores a escala real, se realizan ensayos a escala de laboratorio en reactores batch como el de Potencial Bioquímico de Metano (PBM). En este artículo se presenta una refl exión sobre diferentes aspectos relacionados con este importante ensayo, como la diversidad en la denominación del experimento, las diferentes modifi caciones en las condiciones operacionales y experimentales, el uso de diferentes unidades de medición, las ecuaciones de cálculo usadas para la cuantifi cación del metano, entre otros, que han dado lugar a diversas propuestas metodológicas las cuales difi eren en factores que condicionan su aplicación y la comparación de los resultados con otros estudios. Con esta refl exión se ratifi ca la utilidad de este ensayo pero también la necesidad de estandarizarlo, por lo cual es recomendable reportar las condiciones experimentales y operacionales y las unidades adecuadas, para evitar confusiones metodológicas y permitir una mayor reproducibilidad. Adicionalmente, se debe profundizar en el análisis metodológico de los diferentes métodos de medición y así obtener resultados comparables. Palabras clave: digestión anaerobia, biodegradabilidad anaerobia, potencial bioquímico de metano -PBM, residuo orgánico. AbstractAnaerobic digestion is a biological process that achieves two purposes simultaneously, waste treatment to control environmental pollution and the recovery and valorization of by-products generated: methane as a source of renewable energy and digestate for agricultural purposes. To determine the methane production capability, the anaerobic biodegradability of an organic substrate, the selection of potential substrates and inoculums and the performance prediction of full-scale digesters, bench scale procedures as Biochemical Methane Potential (BMP) test, are performed. This article shows a refl ection on different aspects related to this important test, such as the diversity in the experiment denomination, the different modifi cations in operational and experimental conditions, the different use of measurement units, 95Cita: Cárdenas-Cleves LM, Parra-Orobio BA, Torres-Lozada P; Vásquez-Franco CH.
