SCHNEIDERS, Danieli et al. Specific Methanogenic Activity (SMA) of industrial sludge from the aerobic and anaerobic biological treatment. Rev. Ambient. Água [online]. 2013, vol.8, n.2, pp.135-145. ISSN 1980-993X.  http://dx.doi.org/10.4136/ambi-agua.1098.

In this study, specific methanogenic activity (SMA) tests were performed on textile sludge and food industry sludge. The textile sludge from an activated sludge was collected at the entrance of the secondary biologic clarifier and the food sludge was collected in a UASB reactor. Once collected, the sludges were characterized and tested for SMA. It was found that the microrganisms present in the food sludge had SMA of 0.17 gCOD-CH4 gSSV.d-1 and 337.05 mL of methane production, while the microrganisms of the textile sludge presented 0.10 gCOD-CH4 gSSV.d-1 of SMA and 3.04 mL of methane production. Therefore, the food sludge was more suitable to be used as a starting inoculum in UASB.

Palavras-chave : Industrial sludge; specific methanogenic activity; methane.
