Manual bicarbonate monitoring<\/h2>\n

Long-term proven process control for biogas plants – The importance of the bicarbonate parameter<\/strong><\/p>\n

For efficient biogas production, digested sludge bacteria require a pH value in the range of around 6.5 to 8. Stabilization of the pH value in this range is mainly achieved (> 85 %) by the bicarbonate (= buffer substance) released in large quantities during anaerobic decomposition. Process disturbances regularly lead to increased concentrations of free fatty acids (FFA) or to decreasing bicarbonate contents, as the acids consume bicarbonate. However, the buffering effect of the bicarbonate means that the pH value is hardly reduced at first. Only if the disturbance lasts for a long time and the supply of bicarbonate is largely exhausted does a rapid drop in the pH value occur and subsequently a reduction or, in extreme cases, a failure of biogas production.<\/p>\n
