The
average organic loading rate (OLR) was 1.3 kg-COD/m3/d. During
the first 1.5 months of ABR operation (startup), the influent TSS and
COD averaged 1700 ± 1800 mg/L and 2500 ± 2800 mg/L, respectively.
This was attributed to a failure to flush the sampling line
prior to collection. During this time, effluent TSS levels were low, at
47 ± 19 mg/L, and effluent COD (440 ± 50 mg/L) was very similar to
the two year average of 410 ± 60 mg/L. The first two months of data
were not included in the performance analyses.
