Comparing sludge production under aerobic and anoxic conditions

The results of 32 batch tests demonstrate a significant difference in biomass yield under anoxic and aerobic conditions using a variety of soluble substrates. An anoxic yield of 0.402 mg particulate COD/mg consumed COD was calculated which is 62% of the corresponding aerobic yield of 0.645 mg particulate COD/mg consumed COD. Batch tests were performed under anoxic and aerobic conditions using a seed of either activated sludge from one of two …
