Influence of microwave pre-treatment on sludge solubilization and pilot scale semi-continuous anaerobic digestion.
Anaerobic digestion is widely applied for the recovery of energy from waste activated sludge. Pre-treatment methods are of high interest to increase the biodegradability of the sludge and to enhance the digestion efficiency. This paper studies the application of a microwave pre-treatment. An experimental set-up of two pilot scale semi-continuous digesters was used. During a long term experiment...
متن کاملThermophilic Aerobic Digestion of Activated Sludge; Reduction of Solids and Pathogenic Microorganisms
In the temperature range of 10 to 80 ºC and in a batch digester, a typical activated sludge was digested aerobically. Reaction rate constants were determined by measuring the amounts of volatiles removed from the suspended solids at different time intervals during the process. The maximum value of the reaction rate constant (0.45 d-1) occurred in the temperature...
متن کاملIsolation, identification and utilization of thermophilic strains in aerobic digestion of sewage sludge.
Two representative thermophilic bacterial strains (T1 and T2) were isolated from a one-stage autothermal thermophilic aerobic digestion pilot-scale reactor. 16S rRNA gene analysis indicated that they were Hydrogenophilaceae and Xanthomonodaceae. These isolated strains were inoculated separately and/or jointly in sewage sludge, to investigate their effects on sludge stabilization under thermophi...
متن کاملTransformation and characterisation of dissolved organic matter during the thermophilic aerobic biodegradation of faeces.
We conducted a comparison of the characteristics of dissolved organic matter (DOM) taken from the bio-toilet and other sources. A characterisation of DOM was carried out to assess the stability of the compost generated during the thermophilic and aerobic biodegradation of faeces. In addition, levels of soluble microbial products generated in the bio-toilet composting reactor were compared with ...
متن کاملThermophilic Aerobic Digestion of Activated Sludge; Reduction of Solids and Pathogenic Microorganisms
In the temperature range of 10 to 80 oC and in a batch digester, a typical activated sludge was digested aerobically. Reaction rate constants were determined by measuring the amounts of volatiles removed from the suspended solids at different time intervals during the process. The maximum value of the reaction rate constant (0.45 d ) occurred in the temperature range of 55-60 ̊C. Removal of indi...
