This work deals with steady-state simulation study of a
process formed by a microalgae-bacteria photobioreactor
(PBR) in an activated sludge configuration. In particular,
the process behavior in terms of variations in the sludge
retention time and carbon dioxide (CO2) injected is
presented. The optimization is done by considering the
total PBR volume as two volumes in series, and aiming
for the minimal substrate concentration in the effluent,
for a given external light and CO2 injected. Results
suggest that it is possible to obtain an optimum volume
distribution of the process that gives a lower effluent
substrate concentration compared to the same process
using a single volume.
