This batch test determined the main indicator for the
behavior of microorganisms under aerobic condition in the system.
According to these values microorganisms in the sludge
sample were more voracious than the normal for the uptake
of phosphorus because these microorganisms release large
amounts of phosphorus in the anaerobic zone in the system,
its ability accumulate phosphorus inside cells becomes more
than traditional, therefore we can conclude that the performance
of uptake operation in case of EM addition was more
active in the aerobic zone.
