Abstract

In this study a new
mathematical model to quantify greenhouse gas emissions (namely, carbon
dioxide and nitrous oxide) from membrane bioreactors (MBRs) is
presented. The model has been adopted to predict the key processes of a
pilot plant with pre-denitrification MBR scheme, filled with domestic
and saline wastewater. The model was calibrated by adopting an advanced
protocol based on an extensive dataset. In
terms of nitrous oxide, the results show that an important role is
played by the half saturation coefficients related to nitrogen removal
processes and the model factors affecting the oxygen transfer rate in
the aerobic and MBR tanks. Uncertainty analysis showed that for the
gaseous model outputs 88–93% of the measured data lays inside the
confidence bands showing an accurate model prediction.
