{"id":252,"count":2,"description":"The importance of bicarbonate monitoring\r\nBacteria in anaerobic digesters require a pH value in the range of around 6.5 to 8 in order to produce biogas efficiently. The stabilization of the pH value in this range is mainly achieved (> 85 %) by the release of large amounts of bicarbonate (a buffer substance) from the anaerobic decomposition of organic waste.\r\nProcess interruptions, such as overfeeding, often lead to increased concentrations of free fatty acids (VFA) and decreasing amounts of bicarbonate as these acids consume the bicarbonate.\r\nIf these interruptions continue, the supply of bicarbonate is depleted, leading to a rapid drop in pH and subsequently a reduction in biogas production and, in extreme cases, complete biological breakdown resulting in plant failure.","link":"https:\/\/fitec.com\/en\/product-category\/biology\/","name":"Biology","slug":"biology","taxonomy":"faq_category","parent":0,"meta":[],"_links":{"self":[{"href":"https:\/\/fitec.com\/en\/wp-json\/wp\/v2\/faq_category\/252","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/fitec.com\/en\/wp-json\/wp\/v2\/faq_category"}],"about":[{"href":"https:\/\/fitec.com\/en\/wp-json\/wp\/v2\/taxonomies\/faq_category"}],"wp:post_type":[{"href":"https:\/\/fitec.com\/en\/wp-json\/wp\/v2\/avada_faq?faq_category=252"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
