Increasing the rate of CH4 in thebiogas is very important in terms of the efficient evaluation of the resources as well as the efficient fulfillment of energy demand. One of the methods that can be used for this purpose, also known as co-fermentation, is to process different organic wastes, at a certain rate. Although the fermentation of organic waste mixtures in the specified amounts contributes to the increase of the CH4 ratio in the biogas content, it may cause the halt of biogas production in excess of the amounts determined in the organic waste mixture ratios. In this study, improvements in biogas plant automation are presented and proposed to prevent digester failure in plants producing biogas with co-fermentation.
