The projected levels of incoming fish to process was not realized and the
decrease in operations resulted in lower flows and longer retention times
through the treatment facility than expected.
aeration system was constructed a year later (September, 1976), hereafter
called the pilot plant, to test lower retention times and higher loadings.
Table 5 summarizes the design criteria for the pilot plant, and Figure 4
shows a diagram of the facility.
