Resumen:
This work deals with optimization of a hybrid system for simultaneous bio-hydrogen
production and C-N removal by a combined anaerobic-aerobic treatment method. The
global model couples kinetics, hydrodynamics and bioparticle subsystem for each
reactor model. An existing set of experimental data is used for model validation.
Fluctuating operation conditions such as disturbances in the organic loading rate, feed
and recycle flow rates result in strong numerical discontinuities that are included in the
simulation schedules. Optimization results are based on maximized a pondered function
involving the hydrogen production rate and C-N removal efficiency subjected to (pH,
DO and nitrite) path constraints and interior- and end-point constraints related to the
(COD and nitrogen) pollutant concentration, and manipulating feed, recycle and cations
flow rates using piecewise constant functions. gOPT tool of gPROMS was used to
perform the dynamic optimization.
