Resumen:
In the last two decades, complex systems for simultaneous carbon and nitrogen (CN) 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.+-N concentration and transmembrane pressure is obtained.
