In recent years there has been an increasing interest in the development of hybrid biofilm reactors,especially in the upgrading of existing WWTP that are no longer able to respect concentration limits. In fact,today’s challenge is the achievement of a good aquatic state for the receiving water bodies according to theWater Framework Directive requirements, which indeed limit even more the continuous emissions, i.e.coming from WWTP. This paper presents the setting up of a mathematical model for the simulation of ahybrid MBBR system; the model calibration/validation has been carried out considering a field gatheringcampaign on an experimental pilot plant. The main goal is to gain insight about MBBR processes attemptingto overcome main shortcomings in particular referring to the modelling aspects. The model is made up oftwo connected sub-models for the simulation of the suspended and attached biomass. The model is mainlybased on the concepts of the activated sludge model No. 1 (ASM1) for the description of the biokineticprocess both for the suspended and for the attached biomass. The results show a good agreementbetween predicted and observed values both for the attached and for the suspended biomass moreoverthey are encouraging for further researches.
