Abstract
The slurry bioreactor system is an effective means for treating highly sali ne food wastes, which may not be recycled as composts. The effect of aerati on rate was investigated in a slurry bioreactor as a major factor affecting the slurry-phase decomposition of food wastes. The aeration rate affected significantly the decomposition performance and the composition profiles of the liquid and solid phases. The decomposed carbon was almost linear with oxygen consumption, indicating that the slurry-phase decomposition of food wastes was limited by oxygen transfer. The oxygen requirement for decomposi ng 1 g organic carbon in food wastes was estimated to be 61.5 g O-2.
