Comparism Analysis of Energy Content of Biogas and Its Physiochemical Properties

Abstract

The correlations of energy content of biogas and physicochemical properties from cow manure and co-digestible as single and double substrates were investigated in this study. The blend that gives the highest energy, effect of anaerobic digestion on fertilizer values of the input slurry and relationship between the biogas yields were investigated. The experiment was performed at a constant temperature of 400C with a retention period of 16 days. The physicochemical properties of the slurries before and after digestion showed that the percentages of potassium, phosphorus, nitrogen and crude protein contents for all the samples batches increased. The blend of cow dung and plantain wastes in the 1:3 yielded the highest energy content and volume of biogas. This ratio can be effective for biogas production, mitigate the problems of energy shortage, fertilizer and uncontrolled waste disposal.
