Abstract
The aim was to evaluate individual volatile fatty acids for their suitability for use in the identification of unbalance in biogas reactors. It was sought to find the acids the concentration of which increases after accidents which lead to unbalance, which were most significantly changed in concentration during unbalance, and which increased in concentration under all forms of unbalance. Tests were made under controlled laboratory conditions, process data from larger plants were evaluated for purposes of comparison, the influence of the individual concentration in the limitation of the biomass conversion process was clarified by batch tests, and information was culled from relevant literature on unbalance and the interrelations of sub-processes of anaerobic digestion. These sub-processes, in other words the interaction of bacteria groups in a balanced anaerobic digestion process producing methane from organic wastes, are described in considerable detail. Graphs, tables and diagrams illustrate the text. (AB) 27 refs.
