 The influence of grease trap sludge sterilization on the performance of anaerobic co-digestion of sewage sludgeA. Grosser, E. Neczaj, Anna Jasinska and P. Celary Renewable Energy, 2020, vol. 161, issue C, 988-997 Abstract: The effect of sterilization of grease trap sludge on the performance of their joint anaerobic digestion with sewage sludge was investigated. The process was carried out in two continuously stirred-tank glass reactors at mesophilic conditions. The hydraulic retention time was 10 days, and the experiment was divided into three stages. In two stages, anaerobic digestion of sewage sludge was carried out. In the first stage, the batch assay was applied to promote the development of an anaerobic community. In the second stage, the reactors were fed with sewage sludge in a semi-continuous regime. Meanwhile, in the next step, grease trap sludge was co-digested with sewage sludge. For the first period of the 3rd stage, grease trap sludge without sterilization was dosed into feedstock. In the last period, waste prior to introduction to the feedstock, was sterilized at 133 °C for 20 min at a steam pressure equal to 3 bars.
