Abstract :

Anaerobic digestion of goose manure was adopted in semi-continuous stirring tank reactors. The CSTR was run at three different organic loading rates: 1.4 gVS/L/day, 2.9 gVS/L/day and 4.4 gVS/L/day. The organic loading rate of 2.9 gVS/L/day was proved as the optimum loading rate with maximum methane enhancement. At high organic loading rate the anaerobic process inhibition was observed. Overall, smooth methane production was observed by the goose manure without ammonia inhibition. Statistically, the methane production by low TS content CSTR was found more significant as compared with the high TS CSTR anaerobic digestion of goose manure. The highest VS and CODs removal was also belonged to the 6% TS basis CSTRs. The pH was found optimum for the microbial activities during the whole anaerobic digestion period. The total volatile fatty acids (TVFAs), soluble chemical oxygen demand (CODs), pH, total available ammonia (TAN), free ammonia (FA) and alcohol production was recorded at each three days interval during the whole anaerobic digestion period. Due to organic loading management method almost 50% methane enhancement was recorded.
