This work shows the results of investigations performed with the objective of optimizing methane production from dairy wastewater in anaerobic reactors through the adaptation of microbial populations towards a more complete degradation of high methane yielding substrates. The innovative aspect of this work lies on the use of a novel operating mode – intermittent operation – that allows a raising of methane yield of over 20% in relation to what is obtained with conventional (continuous)...
