Thermophilic versus Mesophilic Anaerobic Digestion of Sewage Sludge: A Comparative Review
During advanced biological wastewater treatment, a huge amount of sludge is produced as a by-product of the treatment process. Hence, reuse and recovery of resources and energy from the sludge is a big technological challenge. The processing of sludge produced by Wastewater Treatment Plants (WWTPs) is massive, which takes up a big part of the overall operational costs. In this regard, anaerobic...
متن کاملAnaerobic Co-digestion of Sewage Sludge with Cheese Whey under Thermophilic and Mesophilic Conditions
Anaerobic digestion of sewage sludge (SS) and co-digestion with cheese whey (CW) was evaluated in batch conditions under mesophilic and thermophilic regimens. Results indicated that the co-digestion can be successfully attained despite some inhibitory stages that may be initially present due to the accumulation of volatile fatty acids. Degradation of the mixture SS-CW followed a similar pattern...
متن کاملOptimization of Anaerobic Digestion of Sewage Sludge Using Thermophilic Anaerobic Pre-Treatment
In this study, we investigated by running continuous stirred tank reactor the effects of different thermophilic temperatures (55, 60, 65, 70, 75 and 80C) for different hydraulic retention times (0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 days, respectively) on the pretreatment of sewage sludge. We found that hydrolysis was mainly determined by temperature instead of hydraulic retention time, i.e. the high...
متن کاملFrom grass to gas: microbiome dynamics of grass biomass acidification under mesophilic and thermophilic temperatures
BACKGROUND Separating acidification and methanogenic steps in anaerobic digestion processes can help to optimize the process and contribute to producing valuable sub-products such as methane, hydrogen and organic acids. However, the full potential of this technology has not been fully explored yet. To assess the underlying fermentation process in more detail, a combination of high-throughput se...
متن کاملDestruction by anaerobic mesophilic and thermophilic digestion of viruses and indicator bacteria indigenous to domestic sludges.
In raw sludges and in mesophilically and thermophilically digested anaerobic sludges, large variations in numbers of viruses occurred over narrow ranges of numbers of fecal coliforms, total coliforms, and fecal streptococci, demonstrating that the bacteria were poor quantitative reflectors of the numbers of the viruses detected. Mesophilic and thermophilic digestion of anaerobic sludges destroy...
