CEBADERO DE TERNEROS at Asturias, Spain – Hong Kong Investment Network
This paper presents the study of co-digestion of two types of organic wastes: Co-digestion of sewage sludge and cattle manure has the advantage of sharing processing facilities, unifying management methodologies, reducing operating costs and dampening investment and temporal variations in composition and production of each waste separately.
The aim of this work was to select suitable operating conditions both composition and temperature of anaerobic co-digestion process of cattle manure and sewage sludge to optimize the process in the biogas generation.
The batch tests have been developed at mesophilic and thermophilic conditions to determine the anaerobic biodegradability of three different mixtures of cattle manure and sewage sludge, both in static or stirring conditions.
The obtained experimental results indicate that the anaerobic biodegradability of raw sludge and cattle manure mixtures df more efficient at thermophilic conditions since a greater elimination of organic matter with a greater methane yield is obtained. Also, it is verified that a higher amount of cattle manure in the mixture means a higher alkalinity and a greater percentage of methane in biogas.
