Secondary title:	Comparison of the simulation tools WEST and GPS-X in the case of MBBR reactor
Secondary abstract:	The aim of this work was to evaluate two simulation tools, WEST and GPS-X, by setting a model of MBBR reactor. The evaluation was based on an existing simulations with a model constructed in GPS-X. Within this work, the same simulations were reconstructed by setting a model in WEST. To this end, the data from Central Wastewater Treatment Plant Domžale- Kamnik was used, where the laboratory pilot plant was operating from October 2005 to May 2006. The pilot MBBR was filled with K1 biocarriers, produced by AnoxKaldnes. Using artificial wastewater, good conditions for autotrophic biomass growth were achieved. A mathematical model of the MBBR reactor was built in WEST, which includes typical biochemical processes of wastewater treatment as well as the transport processes of the substrate from the bulk liquid into the biofilm. Using the model we performed three different simulations in WEST. For the first one, the same values of the parameters were used as those in GPS-X, which produced a simulation that differed significantly compared to the simulation obtained with GPS-X. After running the sensitivity analysis, we calibrated some parameters and achieved better (second) simulation, fitting well the simulation, obtained by GPS-X. The aim of the third simulation was verification of the WEST default parameter values. Slight modification of those parameters was needed in order to achieve good fit to the measured values on the pilot plant. Final result of this work is the comparison of the MBBR models applied in GPS-X and WEST and of the parameter values used in both tools. Apart from some conceptual differences of the two models, we also point to the differences in the computational times and to the numerical stability of the simulation tools.
