3.1. Process performance
The WWTP presented over 94 and 91% removal rates for COD and
TKN respectively, during the measurement campaign. Some of the process
parameters and influent and effluent characteristics of theWWTP
are presented in Table 1. The operational mode of the bioreactor was
the typical of a plug–flow system, creating a DO gradient across the aerated
zones as detailed in Table 1.
