Model Calibration for a Post-Denitrification Moving Bed Biofilm Reactor
Fluidized fixed film technologies, namely IFAS and MBBR, are gaining acceptance due to a combination of current reasons. In order to understand and optimize designs of these systems, process modeling and simulation are powerful tools. However, the need to calibrate these models is not always satisfied, either due to lack of understanding of the complexities or availability of good quality data. A post-denitrification MBBR pilot study was conducted at DCWASA's Blue Plains AWTF during 2008. This paper presents the development and calibration of GPS-X model for this pilot study. The calibrated model is then used to generate dynamic simulations and compare with the plant performance. It can further be used for optimization as well as investigation of process issues such as auto-regulation of biofilm and half saturation coefficients.
