Development of a model combining ASM and ADM using the interfaces approach : N and COD mass continuity

Abstract : In order to deal with the environmental problems associated with the industrialization of the animal production and at the same time considering energy costs increasing, a piggery wastewater treatment process consisting of combined anaerobic digestion and biological nitrogen removal was developed. This contribution presents a modelling framework in order to optimize the whole process. Modified versions of the well-established ASM1 and ADM1 models have been used. The ADM1 was extended with biological denitrification and pH calculation and liquid gas-transfer were modified to take into account the effect of associated components. Finally, two interfaces (ADMtoASM and ASMtoADM) were built in order to combine both models. These interfaces set up the COD, nitrogen, alkalinity and charge fractionation between both models. However, for the mass continuity between both models, some hypotheses were considered and evaluated.
