Date of Defense 1976-09-15 Availability restricted AbstractEvaluation of the data from the series of batch experiments has led
to the following conclusions:
l. Currently used methods of quantifying oxygen uptake rate,
especially for batch reactors, yield values of oxygen
utilization considerably lower than those predicted by
mass balance considerations for these three wastes. In
the face of Blok's published data indicating much better
results with a short run reactor, it must be assumed
that the length of run selected was at least partially
2. While quantitatively unsatisfactory, the methods for
determining oxygen uptake used in these experiments
seem to be of some use as monitors of biological
systems. Changes in slope of the oxygen utilization
curve were found to be more apparent at lower loadings.
