At the heart of biogas plants is the biogas itself, and biogas production process involves bacterial consortium to work along with.
How best to deal with the microbial groups is the art of making biogas that is fine in quality and moderate in quantity; which is always a trade-off: high quantity biogas is usually associated with poorer quality, i.e lower methane per mass or volume of substrate digested.
The balance between biogas quantity and quality is really the main concern of biogas production operators – and for this, a bit of science is required.
The following three books give a clear guide to the anaerobic process as a whole, its monitoring and how to tackle problems commonly occur in an upset anaerobic process. I would always recommend these 3 books for anyone interested to dive deeper into Anaerobic Digestion (AD) as I found these books to be so useful in my day to day experience working on anaerobic process.
Without further ado, here they are:
Those books—along with thorough field observation—would be sufficient to run a balanced and well-maintained process. I can assure you that these books would make you a more knowledgeable personel in this particular field. 😉
