Influence of pH on anaerobic digestion of municipal bio-wastes
Municipal bio-wastes-MBW are characterized by their high content of organic matter, humidity, nutrients, and additionally are wastes easily acids, which makes them a source of pollution when are improperly disposed. Anaerobic digestion-AD is a technological alternative for MBW pollution control as well as for methane production as a renewable energy source; however, parameters such as pH can affect the process. This study evaluated at laboratory scale thought Biochemical Potential Methane-BPM assays at a temperature of 30oC during 40 days, the influence of pH on the MBW-AD. The pH values tested ranged from 5.5 to 8.0 units, using as inoculum sludge coming from the sludge anaerobic digestion of a domestic wastewater treatment plant. It was noticed that the acid pH between 5.5 and 6.0 units had the lowest methane production, 70.0 and 71.0mLCH4*gVS-1 respectively; while pH values near to the neutrality achieved the best results, being the highest production of methane corresponding to a pH of 7.0 units, reaching a value of 126.0mLCH4*gVS-1. Similarly, it was found that pH values from 7.0 to 8.0 units had the best buffer capacity, ensuring stability of the anaerobic process and avoiding inhibition phenomena. To achieve this condition, it is necessary to apply pH adjust due to the acid characteristics of the MBW.

Anaerobic digestion-AD is a technological alternative for MBW pollution control as well as for methane production as a renewable energy source; however, parameters such as pH can affect the process. This study evaluated at laboratory scale thought Biochemical Potential Methane-BPM assays at a temperature of 30oC during 40 days, the influence of pH on the MBW-AD.

Los biorresiduos de origen municipal-BOM, se caracterizan por su alto contenido de materia orgánica, humedad y nutrientes, además de ser residuos fácilmente acidificables, lo que los convierte en una fuente contaminante cuando se disponen inadecuadamente. La digestión anaerobia-DA es una alternativa tecnológica para el control de la contaminación de los BOM y la obtención de una fuente de energía renovable, como el metano; sin embargo, variables, como el pH, pueden afectar el proceso. Este estudio evaluó, a escala de laboratorio, mediante ensayos de Potencial Bioquímico de Metano-PBM, a una temperatura de 30oC, durante 40 días, la influencia del pH sobre la DA de BOM. Los valores de pH del sustrato variaron entre 5,5 a 8,0 unidades, utilizando como inóculo lodo, proveniente de la biodigestión anaerobia de lodos, de una planta de tratamiento de aguas residuales domésticas. Se evidenció que los pH ácidos correspondientes a 5,5 y 6,0 unidades, presentaron la menor producción de metano, del orden de 70,0 y 71,0 mLCH4*gSV-1, respectivamente, mientras que los pH cercanos a la neutralidad, lograron los mejores resultados, siendo la producción a un pH de 7,0 unidades la mayor, la cual, fue 126,0mLCH4*gSV-1. Los resultados están acordes con el comportamiento de la capacidad buffer, que fue más adecuada, entre 7,0 y 8,0 unidades, garantizando estabilidad del proceso anaerobio y evitando así la ocurrencia de fenómenos de inhibición. Para lograr estos niveles de pH, se hace necesario adicionar un alcalinizante, debido a las características ácidas de los BOM.
