Resumen:
In the last two decades, complex systems for
simultaneous carbon and nitrogen (C- N) removal have been proposed. Various
configurations of anaerobic and aerobic reactor systems were applied including
submerged membranes to obtain an excellent effluent quality. However, in this
systems membrane fouling is still a major problem that hinders their more
widespread and large-scale application. The aim of this work is modeling the
C-N removal and physical separation in a combined anaerobic-aerobic membrane
bioreactor (MBR) system. An example based on a combined anaerobic upflow bed
filter- aerobic MBR system for the treatment of a synthetic high-strength C-N
wastewater was selected to illustrate the model application. A good agreement
between experimental and predicted values of COD and NH4+-N
concentration and transmembrane pressure is obtained. The accurate description
of the macroscopic variables by the proposed model has an additional worth due
to the fact that the kinetic and stoichiometric parameters of the model were
obtained from the literature. The modeling task provides a useful tool for
simulation and optimization of operational strategies and design of these
hybrid systems.
