Influence of Added Co Substrates, Technical and Technological Factors on the Fermentation Process of Municipal Wastewater Sludge

The potential of the sewage sludge as energy resource is not exploited. There are studies that confirm that it is possible to increase the yield of the fermentation process if the conditions are appropriate. This paper presents the specific factors that need to be modified in order to improve the efficiency as well as the materials and the methods that have to be used to achieve the improvement.
