Biogasification of pretreated Reed Sedge peat

OSTI ID:6775280
The anaerobic digestion characteristics of acid treated Reed Sedge peat under mesophilic and thermophilic conditions are described. The effect of acid treatment on methane production from peat is discussed. Types of nutrients used include sewage sludge. Chemical characteristics indicate that anaerobic digestion of peat could be deficient in phosphorus, sodium, potassium, and magnesium. Acid hydrolysis increased gas production and volatile acids. Thermophilic conditions resulted in higher gas and methane yields. Addition of large quantitites of sewage sludge greatly improved methane yield. Diluted digested slurries can be dewatered by vacuum filtration and mechanical pressing into cakes (34% wt solids). (DMC)
