pH control in biotechnological processes like anaerobic digestion is one of the key factors to ensure a high efficiency biogas production process. pH decrease occurs during digestion process due to the rapid acetogenesis which lead to the inhibition of the methanogenesis and further digestion process is limited. The efficiency of anaerobic digestion reactor decreases dramatically and production of methane ( CH 4) in digester stops if pH level drops under pH 6.6. Such problem is common for batch and single-stage digesters with high biomass solid content
