Abstract:
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) systems with the same wastewater purification efficiencies. Results from molecular techniques confirm that this improvement in methane production is due to the development in the intermittent system of a microbial population highly adapted to the metabolization of lipids which are the substrates with higher methane yield potential in dairy wastewater.
