Intensification of Energy Production in the Anaerobic Digestion Process of Sewage Sludge Using Enzymatic Disintegration
This paper presents results of a study on changes in the physical and chemical properties of papain-disintegrated sewage sludge subjected to methane fermentation and the effect of enzymes on the colony number of <i>Escherichia coli</i>, <i>Salmonella</i> spp. and <i>Leg...

| description | This paper presents results of a study on changes in the physical and chemical properties of papain-disintegrated sewage sludge subjected to methane fermentation and the effect of enzymes on the colony number of <i>Escherichia coli</i>, <i>Salmonella</i> spp. and <i>Legionella</i> spp. Fermentation studies were conducted in five batches, in which papain was introduced in amounts representing 0, 1, 2, 3 and 4% (<i>w</i>/<i>w</i>) by weight of the sludge dry matter content. The use of enzymatic disintegration allowed us to intensify the decomposition of organic compounds in the digestion process up to 31% and increase biogas production up to 41% compared to control sludge. At the same time, an almost complete reduction (99–100%) in the colony number of <i>E. coli</i> and <i>Salmonella</i> spp. could be achieved. Therefore, enzymatic disintegration can be competitive with physical or chemical disintegration methods. |
