Description:
The unbalanced nutrients of algal sludge (low C/N ratio) were regarded as an important limitation factor to anaerobic digestion process. Adding high carbon content of waste paper in algal sludge feedstock to have a balanced C/N ratio was undertaken in this study. The results showed adding 50% (based on volatile solid) of waste paper in algal sludge feedstock increased the methane production rate to 1170+/-75ml/lday, as compared to 573+/-28ml/lday of algal sludge digestion alone, both operated at 4g VS/lday, 35^oC and 10 days HRT. The maximum methane production rate of 1607+/-17ml/lday was observed at a combined 5g VS/lday loading rate with 60% (VS based) of paper adding in algal sludge feedstock. Results suggested an optimum C/N ratio for co-digestion of algal sludge and waste paper was in the range of 20-25/1.
