Similar methane conversion/yield values were obtained for PS and SS, while continuous mixing and 35 degrees C have been evaluated as optimal for methane production in PS digestion. Continuous mixing resulted in 50% increased methane yield (600(+/-100) mL/g VSadd.d. SS sludge digestion produced comparable methane yield at 650(+/-100) mL/g VSadd.d showing no effect due to mixing pattern. Settling and dewaterability characteristics of the stabilized PS were superior to stabilized SS samples. A reverse relationship was obtained between settling characteristics and dewaterability for both sludge types.eninfo:eu-repo/semantics/closedAccessSewage sludgeanaerobic digestionbiosolidsettleabilitydewaterabilitymixingConference Object
