Improving biogas generation from pulp mill sludge by pretreatment
The effectiveness of thermal, caustic, and sonication pretreatment methods was examined in improving anaerobic conversion to biogas of secondary sludge samples obtained from a kraft mill and a sulfite mill. All three methods improved the anaerobic digestion rate and the biogas yield of the sludge samples. Thermal pretreatment was the most effective, followed closely by caustic pretreatment, and sonication the least. The total biogas productions per unit of chemical oxygen demand of sulfite sludge and kraft sludge samples were respectively 1.2 and 3 times higher with pretreatments than without. Also, the biogas production from the untreated sulfite mill sludge was 4 times higher than that from the untreated kraft mill sludge.The soluble carbohydrate content in sludge correlates well with the biogas yield and can be used to predict the biogas production potential of the secondary sludge.(Tappi J, June 2010)
