“…The rates were normalized to account for slight differences in biomass concentration between samples, because a new sample was obtained for each phenol injection. This technique was similar to the method of Aitken and McCoy (1993). The test was also performed while a concentrated (fed-batch) feed was continuously delivered to the biomass sample.…”

“…Because of the partial batch nature of SBRs, reactor concentrations of poorly degradable substrates may gradually increase during the cycles and potentially attain inhibitory levels. As a result, poor removal of inhibitory wastewaters has been noted in SBRs, particularly when attempts were made to increase the loading rates (Aitken and McCoy, 1993). When daily loadings are maintained at constant levels, the accumulation of substrates above inhibitory levels can be prevented by either extending the reactor feed period or by increasing the cycle frequency.…”

“…Aitken (1993) evaluated the biological treatment of inhibitory substrates in a batch-operated process, such as the sequencing biological reactor (SBR), and presented an operational strategy for optimizing inhibitory substrate removal. Aitken and McCoy (1993) studied the treatment of nitrosophenol with a SBR and concluded that degradation occurred by co-metabolism in the presence of phenol. Competitive inhibition of the nitrification process was observed in the startup of a pilot-and a full-scale facility treating a biochemical manufacturing waste stream (Nowak and Svardal, 1993).…”
