After reading this article you will learn about the design of bio-gas plant with diagram. The bio-gas plant has been diagrammatically represented in the Fig. 11.1. The size varies with amount of cow dung available. If 50kgs of dung is available from three animals, the bio-gas plant consists of a masonry fermentation tank or a digester, 3.6 metres deep and [...]
After reading this article you will learn about the decomposition of various organic compounds. Different organic residues (plants and animals) contain different groups of organic compounds. So different groups of compounds have their different ease of decomposition. In-spite of having different composition in different organic residues, the ultimate end products of decomposition (particularly of aerobic) are more or less similar. [...]
This article throws light upon the three mechanisms of decomposition of organic residues. The mechanisms are: 1. Enzymes and the Biological Reaction 2. Simple Products of Decomposition 3. Decomposition Action Mechanism # 1. Enzymes and the Biological Reaction: An enzyme is a substance, composed of protein that is capable of lowering the activation energy of other selective compounds enough to [...]
