Tassanee Seedapeng
The cattle manure characterized by total solid of 61.70 gram/litre volatile solid of 46.42 gram/litre was anaerobically fermented by batch operation (250 ml of 1:1 solution). During 12 days, the biogas collected was 41 ml. It was found that the amount of nitrogen increased by 0.18 percent and that phosphorus as P2O5 decreased by 0.09 percent compared to the amount before fermentation. For potassium in the form of K20 it was reduced by 0.16 percent. On the contrary BOD (Biochemical Oxygen Demand) was measured to have increased from the beginning of the fermentation
